Foreword

Manual material handling (MMH) work contributes to a large percentage of the over
half a million cases of musculoskeletal disorders reported annually in the United States.
Musculoskeletal disorders often involve strains and sprains to the lower back, shoulders,
and upper limbs. They can result in protracted pain, disability, medical treatment,
and financial stress for those afflicted with them, and employers often find themselves
paying the bill, either directly or through workers’ compensation insurance, at the same
time they must cope with the loss of the full capacity of their workers.

Scientific evidence shows that effective ergonomic interventions can lower the
physical demands of MMH work tasks, thereby lowering the incidence and severity
of the musculoskeletal injuries they can cause. Their potential for reducing injury-
related costs alone make ergonomic interventions a useful tool for improving a
company’s productivity, product quality, and overall business competitiveness. But
very often productivity gets an additional and solid shot in the arm when managers
and workers take a fresh look at how best to use energy, equipment, and exertion to
get the job done in the most efficient, effective, and effortless way possible. Planning
that applies these principles can result in big wins for all concerned.

This booklet will help you to recognize high-risk MMH work tasks and choose
effective options for reducing their physical demands.

Illustrated inside you will find approaches like:
• Eliminating lifting from the floor and using simple transport devices like carts or dollies
• Using lift-assist devices like scissors lift tables or load levelers
• Using more sophisticated equipment like powered stackers, hoists, cranes, or
vacuum assist devices
• Guiding your choice of equipment by analyzing and redesigning work stations
and workflow

NIOSH and Cal/OSHA are dedicated to finding the bottom line in state-of the-art-
research and turning the results into practical guidance for improving the safety and
health of all workers. We hope you find the MMH booklet a useful and effective
example of our efforts.

Improving Manual
Material Handling in Your
Workplace

Improving Manual Material Handling in Your Workplace

What Manual Material Handling Is
According to the U.S. Department of Labor, handling is defined as:

Seizing, holding, grasping, turning, or otherwise

working with the hand or hands. Fingers are involved

only to the extent that they are an extension of the hand,

such as to turn a switch or to shift automobile gears.

In this publication, handling means that the
worker’s hands move individual containers
manually by lifting, lowering, filling, emptying, or
carrying them.

Why Improve Your Workplace

Manual handling of containers may expose workers to physical conditions
(e.g., force, awkward postures, and repetitive motions) that can lead to injuries,
wasted energy, and wasted time. To avoid these problems, your organization can
directly benefit from improving the fit between the demands of work tasks and the
capabilities of your workers. Remember that workers’ abilities to perform work tasks
may vary because of differences in age, physical condition, strength, gender, stature,
and other factors. In short, changing your workplace by improving the fit can benefit
your workplace by:
• Reducing or preventing injuries
• Reducing workers’ efforts by decreasing forces in lifting, handling, pushing, and
pulling materials
• Reducing risk factors for musculoskeletal disorders (e.g., awkward postures from
reaching into containers)
• Increasing productivity, product and service quality, and worker morale
• Lowering costs by reducing or eliminating production bottlenecks, error rates
or rejects, use of medical services because of musculoskeletal disorders, workers’
compensation claims, excessive worker turnover, absenteeism, and retraining

8

What to Look for

What to Look for
Manual material handling tasks may expose workers to physical risk factors.

If these tasks are performed repeatedly or over long periods of time, they can lead

to fatigue and injury. The main risk factors, or conditions, associated with the

development of injuries in manual material handling tasks include:

• Awkward postures (e.g., bending, twisting)
• Repetitive motions (e.g., frequent reaching, lifting, carrying)
• Forceful exertions (e.g., carrying or lifting heavy loads)
• Pressure points (e.g., grasping [or contact from] loads, leaning against parts or
surfaces that are hard or have sharp edges)
• Static postures (e.g., maintaining ﬁxed positions for a long time)

Repeated or continual exposure to one or more of these factors initially may lead
to fatigue and discomfort. Over time, injury to the back, shoulders, hands, wrists,
or other parts of the body may occur. Injuries may include damage to muscles,
tendons, ligaments, nerves, and blood vessels. Injuries of this type are known as
musculoskeletal disorders, or MSDs.

In addition, poor environmental conditions, such as extreme heat, cold, noise, and
poor lighting, may increase workers’ chances of developing other types of problems.

Types of Ergonomic Improvements
In general, ergonomic improvements are changes made to improve the ﬁt between the
demands of work tasks and the capabilities of your workers. There are usually many
options for improving a particular manual handling task. It is up to you to make informed
choices about which improvements will work best for particular tasks.

There are two types of ergonomic improvements:
1. Engineering improvements
2. Administrative improvements

1. Engineering Improvements

These include rearranging, modifying, redesigning, providing or replacing tools,
equipment, workstations, packaging, parts, processes, products, or materials
(see “Improvement Options”).

9


2. Administrative Improvements

Observe how different workers perform the same tasks to get ideas for improving
work practices or organizing the work. Then consider the following improvements:

• Alternate heavy tasks with light tasks.
• Provide variety in jobs to eliminate or reduce
repetition (i.e., overuse of the same muscle groups).
• Adjust work schedules, work pace, or work practices.
Your
• Provide recovery time (e.g., short rest breaks).
power zone
• Modify work practices so that workers perform work
within their power zone (i.e., above the knees, below
the shoulders, and close to the body).
• Rotate workers through jobs that use different
muscles, body parts, or postures.

Administrative improvements, such as job rotation, can help reduce workers’
exposures to risk factors by limiting the amount of time workers spend on “problem
jobs.” However, these measures may still expose workers to risk factors that can lead
to injuries. For these reasons, the most effective way to eliminate “problem jobs” is
to change them. This can be done by putting into place the appropriate engineering
improvements and modifying work practices accordingly.

Training
Training alone is not an ergonomic improvement. Instead, it should be used together with
any workplace changes made. Workers need training and hands-on practice with new
tools, equipment, or work practices to make sure they have the skills necessary to work
safely. Training is most effective when it is interactive and fully involves workers. Below
are some suggestions for training based on adult learning principles:
• Provide hands-on practice when new tools, equipment, or procedures are
introduced to the workforce.
• Use several types of visual aids (e.g., pictures, charts, videos) of actual tasks in
your workplace.
• Hold small-group discussions and problem-solving sessions.
• Give workers ample opportunity for questions.

10

A Proactive Action Plan

Manual material handling jobs require movement and physical
activity. But how do you find out:
• Why workplace problems are occurring?
• Which work tasks may be causing injuries or production
bottlenecks or decreasing product and service quality?
• What to do about problems once you find them?
• How to reduce your workers’ compensation costs?

One way to answer these questions is to be proactive in your problem
solving. Being proactive simply means finding the problems first
by looking thoroughly around the workplace rather than waiting for
problems to occur. Then improve the fit between the work and the
worker by putting the appropriate changes into place.

The process includes involving workers, observing jobs, making
decisions on effective options, and then taking action. It is important
to involve workers, managers, and supervisors throughout the process.

There are four steps to a proactive action plan:
1. Look for clues.
2. Prioritize jobs for improvements.
3. Make improvements.
4. Follow up.

Step 1: Look for Clues

a. Review written records (e.g., OSHA Log 300, past worker reports
or complaints, and workers’ compensation reports). Your workers’
compensation insurance carrier may offer risk-management services
that can provide workplace assessment surveys.

11


b. Observe work activities. Talk to workers, supervisors, and managers about where
problems exist. Look for warning signs, such as:
• Risk factors in work tasks (e.g., awkward postures, repetitive motions, forceful
exertions, pressure points, staying in the same position for a long time)
• Worker fatigue, discomfort, or reports of related problems
• Workers exhibiting “pain behaviors” (e.g., not moving body parts, self-restricting
their movements, or massaging hands, arms, legs, necks, or backs)
• Workers modifying tools, equipment, or workstations on their own
• Increase in absenteeism, worker turnover rates, or customer complaints
• Decrease in product or service quality or employee morale
• Increase in error rates, rejects, or wasted materials
• Production bottlenecks
• Malfunctioning equipment
• Missed deadlines
• Unnecessary handling and duplication of material and product movement

Make sure to talk to your workers about their ideas for altering work processes,
operations, tools, or equipment. Ask them how they would make their jobs less
physically demanding and more efﬁcient.

c. Use assessment tools - To determine where problems may arise in work tasks, you
may want to use some of the following simple “tools” (see Appendix B):
• NIOSH Manual Material Handling Checklist
• NIOSH Hazard Evaluation Checklist for Lifting, Pushing, or Pulling
• The Awareness Worksheet: Looking for Clues
• Ergonomics Checklist - Material Handling

If the problems are complex, more sophisticated methods may be needed for
addressing your workplace MSDs. More detailed assessment tools for speciﬁc
problems include the following (see Appendix C):
• NIOSH Lifting Equation
• American Conference of Governmental Industrial Hygienists (ACGIH) Threshold
Limit Values (TLVs) for Manual Lifting
• University of Michigan 3D Static Strength Prediction Program
• Ohio State University Lumbar Motion Monitor
• Snook’s Psychophysical Tables

12


Step 2: Prioritize Jobs for Improvements

After detecting the problems, decide which tasks to improve and then set priorities.
Consider:
• The frequency and severity of the risk factors you have identified that may
lead to injuries
• The frequency and severity of complaints, symptoms, and/or injuries
• Technical and financial resources at your disposal
• Ideas of workers for making improvements
• Difficulty in implementing various improvements
• Timeframe for making improvements

Step 3: Make Improvements

The goal of making changes is to improve the fit between the demands of
work tasks and the capabilities of your workers. Combine operations and
processes whenever possible to reduce or eliminate unnecessary manual
handling of materials and products. Depending on the characteristics of
the work and the workers, there may be some changes that will improve a
particular task.

For suggestions on how to improve your work tasks, see “Improvement Options.”

Appendix D contains a tool to help evaluate the improvements
you are considering.

If you need additional help with improvements, consider the following:
• Talk to various employees. Brainstorming with engineers, maintenance
personnel, managers, and production workers is a great way to generate ideas.
• Contact others in your industry. They may have solutions that could also apply
to your problem, saving you time, money, and effort.
• Look through equipment catalogs. Focus on equipment dealing with the types
of problems you are trying to solve.
• Talk to equipment vendors. They may be able to share ideas from operations
similar to yours.
• Consult with an expert in ergonomics. An expert can provide insights into
available improvements, the cost, and the potential value.
• Call Cal/OSHA Consultation Service (only for businesses located in California).
It provides free on-site consultation and advice on occupational safety and health.
• Search the Internet (e.g., Material Handling Industry of America,
www.mhia.org, Material Handling Equipment Distributors Association,
www.mheda.org). See Appendix E for a list of resources on handling materials.
13


Step 4: Follow Up

It is important to follow up in order to evaluate if your improvements have worked.
After a reasonable adjustment period, set a date to follow up on the changes made.
Make sure to evaluate each improvement separately for effectiveness. The following
questions may be helpful:

Has each improvement:
• Reduced or eliminated fatigue, discomfort, symptoms, and/or injuries?
• Been accepted by workers?
• Reduced or eliminated most or all of the risk factors?
• Caused any new risk factors, hazards, or other problems?
• Caused a decrease in productivity and efﬁciency?
• Caused a decrease in product and service quality?
• Been supported with the training needed to make it effective?

If you determine that your improvements have not worked, modify them or try
something different until the risk factors have been reduced or eliminated.

NIOSH Lifting Equation

The Revised National Institute of Occupational Safety and Health (NIOSH) Lifting Equation
(1994) provides guidelines for evaluating two-handed manual lifting tasks. It defines a
Recommended Weight Limit (RWL) as the weight of the load that nearly all healthy workers
can lift over a substantial period of time (e.g., eight hours) without an increased risk of
developing lower back pain. The maximum weight to be lifted with two hands, under ideal
conditions, is 51 pounds. The RWL is based on six variables that reduce the maximum weight
to be lifted to less than 51 pounds.

Consult the Revised NIOSH Lifting Equation (1994) for information to help assess complex
lifting tasks (see Appendix C).

Note: The lifting guidelines suggested by the Revised NIOSH Lifting Equation
are not Cal/OSHA regulatory requirements and are not part of Title 8 of the California
Code of Regulations.

Management Guidelines for Safer Lifting

• Plan the workflow to eliminate unnecessary lifts.
• Organize the work so that the physical demands and work pace increase gradually.
• Minimize the distances loads are lifted and lowered.
• Position pallet loads of materials at a height that allows workers to lift and lower within their power zone.
• Avoid manually lifting or lowering loads to or from the floor.
- Store materials and/or products off the floor.
- Arrange materials to arrive on pallets, and keep materials on pallets during storage.
Use a forklift to lift or lower the entire pallet of material, rather than lifting or lowering the
material individually.
- Arrange to have material off-loaded directly onto storage shelves. Store only lightweight or
infrequently lifted items on the floor.
- Use mechanical devices (e.g., lifts, hoists ) whenever possible.
- Avoid designing jobs that require workers to lift or lower materials to or from floor level.
• For loads that are unstable and/or heavy:
- Tag the load to alert workers.
- Test the load for stability and weight before carrying the load.
- Use mechanical devices or equipment to lift the load.
- Reduce the weight of the load by:
> Putting fewer items in the container.
> Using a smaller and/or lighter-weight container.

- Repack containers so contents will not shift and the weight is balanced.
- Use team lifting as a temporary measure for heavy or bulky objects.
• Reduce the frequency of lifting and the amount of time employees perform lifting tasks by:
- Rotating workers in lifting tasks with other workers in non-lifting tasks.
- Having workers alternate lifting tasks with non-lifting tasks.
• Clear spaces to improve access to materials or products being handled. Easy access allows
workers to get closer and reduces reaching, bending, and twisting.

Employee Guidelines for Safer Lifting

• The use of stretching is appropriate as part of a comprehensive ergonomic program.
Stretching must not be used in place of engineering and/or administrative improvements.
• Check for tags on loads.
• Before lifting, always test the load for stability and weight.
• For loads that are unstable and/or heavy, follow management guidelines for:
- Equipment use
- Reducing the weight of the load
- Repacking containers to increase stability
• Plan the lift:
- Wear appropriate shoes to avoid slips, trips, or falls.
- If you wear gloves, choose the size that ﬁts properly. Depending on the material the gloves
are made of and the number of pairs worn at once, more force may be needed to grasp and
hold objects. For example, wearing a single pair of heat-resistant gloves can reduce your grip
strength up to 40 percent. Wearing two or more pairs of gloves at once can reduce your grip
strength up to 60 percent.
- Lift only as much as you can safely handle by yourself.
- Keep the lifts in your power zone (i.e., above the knees, below the shoulders, and close to the
body), if possible.
- Use extra caution when lifting loads that may be unstable.
• When lifting:
- Get a secure grip.
- Use both hands whenever possible.
- Avoid jerking by using smooth, even motions.
- Keep the load as close to the body as possible.
- To the extent feasible use your legs to push up and lift the load, not the upper body or back.
- Do not twist your body. Step to one side or the other to turn.
- Alternate heavy lifting or forceful exertion tasks with less physically demanding tasks.
- Take rest breaks.

Improvement Options

Avoid lifting from the floor whenever possible. If you must lift from the
floor, do not bend at the waist. The techniques shown below help the
worker to keep the spine in a safer position while lifting from the floor.

Section 1. Easier Ways to Manually Lift, Lower, Fill, or Empty Containers

Use team lifting as a temporary measure until a more permanent
improvement can be found. If possible, try to ﬁnd a co-worker of similar
height to help with the lift.

!
Caution:
Team lifting
can increase
the risk of a
slip, trip, or
fall accident.

Team lifting can reduce the load in half.
Discuss your lifting plan so you
don’t make surprise movements.

Use a scissors lift, load lifter, or pneumatic lifter to raise or
lower the load so that it is level with the work surface.Then
slide the load instead of lifting.

Easier Ways to Manually Carry Containers

• Improve your grip.
• Reduce stress on your back and shoulders.
• Reduce contact pressure on your shoulders and hands.
• Reduce the effort and force needed to perform
work tasks.

Management Guidelines for Safer Carrying

• Plan the workﬂow to eliminate unnecessary carrying.
• Slide, push, or roll instead of carrying, when appropriate.
• Organize the work so that the physical demands and work pace increase gradually.
• Reduce the distances that loads are moved to a minimum. If long trips are required, use equipment.
• For loads that are unstable and/or heavy:
- Tag the load to alert workers.
- Test the load for stability and weight before carrying the load.
- Use mechanical devices or equipment to carry or move the load.
- Reduce the weight of the load by:
> Putting fewer things in the container.
> Using smaller and/or lighter weight containers.
> Dividing the load between two containers and carrying one in each hand.
- Repack the containers so contents will not shift and the weight is balanced.
- Use team carrying as a temporary measure for heavy or bulky objects.
• Reduce the frequency and amount of time workers carry materials by:
- Rotating workers in carrying tasks with other workers in non-carrying tasks.
- Having workers alternate carrying tasks with non-carrying tasks.

Employee Guidelines for Safer Carrying

- Avoid carrying large or bulky loads that limit or obstruct your vision.
- Slide, push, or roll instead of carrying when appropriate.
- When there is a choice, push instead of pull.
- Carry only as much as you can safely handle by yourself.
- Try to avoid slopes, stairs, or other obstacles that make carrying materials more difficult.
- Beware of and try to avoid slippery floors (e.g., liquids, ice, oil, and fine powders).
- Use extra caution when moving loads that may be unstable.
• When carrying:
- Keep loads close to your body.
- Make sure you have a clear view of the path.
- When carrying containers with one hand, alternate hands.
- Whenever appropriate, use two hands to carry containers.
- Alternate heavy or forceful exertion tasks with less physically demanding tasks.
- Take rest breaks.

Improvement Options

Redesign the container so it has handles, grips, or handholds.

Hold the container close to the body.

Alternatives to Manual Handling of
Individual Containers
• Change the container.
• Use a tool.
• Use non-powered equipment.
• Use powered equipment.

Guidelines for Equipment Use

Equipment
• Know your load and buy equipment of appropriate capacity. Remember, lighter-weight
equipment is easier to move.
• Choose equipment appropriate for the material(s) being handled, the layout and design of your
workplace, and the work tasks being performed (see Appendix B).
• Consider using powered equipment —rather than non-powered— when pushing and pulling
forces are excessive (see Appendix C, Snook’s Psychophysical Tables).
• If available, select equipment with vertical handles so workers’ hands can be in their
power zone.
• Choose wheeled equipment which minimizes start forces (inertia) and reduces rolling
resistance. The amount of force required to move loads with wheeled equipment depends on a
number of factors including the:
- Weight and shape of the load
- Type and condition of the ﬂoor surface (e.g., smoothness, density, and other factors)
- Route taken (e.g., slopes, obstacles, and other factors)
- Type of wheels (i.e., the materials they are made of)
- Size of wheels (larger wheels a minimum of 6 inches in diameter move more easily over
holes, bumps, and ﬂoor irregularities)
- Maintenance of wheels; it is important to clean, lubricate, and/or replace wheels on a
regular basis.
• Ground all electrically operated equipment
• Make sure equipment alarms and warning devices are audible and working properly.
• Inspect and maintain equipment according to manufacturers’ recommendations.
• Follow all manufacturers’ recommendations for proper equipment use.

Work Environment
• Clear the aisles and doorways for safe passage and maneuvering of equipment.
• Set barriers that prevent employees from coming close to or beneath supported or
moving loads.
• In tight spaces, use equipment with four swivel casters or wheels. Loads are easier to
turn and control.

Work Practices
• Train employees on proper equipment use and appropriate work practices.
• Push and pull equipment with the entire body instead of with just the arms and shoulders.
• When pushing or pulling use both hands when feasible.
• To move heavy loads over long distances, either reduce the load or use powered equipment.
• Inspect pallets before loading or moving them.

Section 3. Alternatives to Manual Handling of Individual Containers

Change the container

Instead of lifting and pouring from the drum, insert a siphon or
a pump.

!
Caution: To prevent cross-contamination, chemical
incompatibility, and ﬂammability hazards, do not interchange
pumps or siphons among different containers.

Appendix A Administrative Improvements
Administrative improvements include changing work practices or the way work
is organized. Administrative improvements require continual monitoring by
management and employee feedback to make sure the improvements are effective.

Provide variety in jobs

There are a couple of ways to increase variety in jobs. Job rotation means rotating
employees through different jobs. Job enlargement means increasing the variety by
combining two or more jobs or adding tasks to a particular job. To be effective, both
improvements rely on changing jobs and tasks so that they differ in the:
• Muscles or body parts used
• Working postures
• Amount of repetition
• Pace of work
• Amount of physical exertion required
• Visual and mental demands
• Environmental conditions

Adjust work schedules and work pace

New workers who are not used to the physical demands of the job or those returning
from long absences should be gradually introduced to a normal work pace and
workload like an athlete in spring training.

Provide recovery time

Recovery periods (i.e., muscle relaxation periods) can help prevent fatigue and injury
to muscles. Several short breaks can reduce the frequency and duration of physically
demanding activities. Ask employees for their ideas for the best rotation or break
schedules to reduce the physical demands of their jobs. Their suggestions can help
you integrate the physical demands of jobs with the environmental and organizational
demands of the workplace.

50

Appendix A. Administrative Improvements

Modify work practices

Pay close attention to how the work is being performed. Employees should be
encouraged to be comfortable, change positions, and stretch during work periods.
The human body is stronger, more efﬁcient, and less prone to injury when work is
performed in midrange postures and within the power zone.

Midrange postures mean postures in which the joints of the neck, back, legs, arms,
and wrists are not bent in extreme positions. The power zone is above the knees,
below the shoulders, and close to the body. The principle of the power zone is that
in this area workers have the greatest power to perform heavier work tasks with less
bending, stooping, or reaching.

Appendix C Analysis Methods
The following methods are comprehensive tools designed to provide a detailed
analysis of various types of manual material handling tasks. They can be used to
evaluate lifting, lowering, pushing, pulling, carrying, and other activities.

NIOSH Lifting Equation

The NIOSH Lifting Equation is a tool used to evaluate manual lifting tasks. This
equation allows the user to insert the exact conditions of the lift (e.g., height, distance
lifted, weight, position of weight relative to body, etc.). This equation accounts for
asymmetrical lifts and objects that are difﬁcult to grasp.
http://www.cdc.gov/niosh/94-110.html

ACGIH Threshold Limit Values (TLVs) for Lifting

The American Conference of Governmental Industrial Hygienists (ACGIH)

recommends guidelines for safe lifting. The Threshold Limit Values (TLVs) for lifting

recommend upper and lower limits based upon frequency, duration, and other risk

factors associated with lifting.

The following ACGIH Publications may be helpful:

University of Michigan 3D Static Strength Prediction Program

3D Static Strength Prediction Program software predicts static strength requirements
for tasks such as lifts, presses, pushes, and pulls. The program provides an
approximate job simulation that includes posture data, force parameters, and male/
female anthropometry. The results include the percentage of men and women who
have the strength to perform the described job, spinal compression forces, and data
comparisons to NIOSH guidelines. The user can analyze torso twists and bends
and make complex hand force entries. Analysis is aided by an automatic posture
generation feature and three-dimensional human graphic illustrations.

Appendix C. Analysis Methods

Ohio State Lumbar Motion Monitor

Traditionally, most workplace ergonomic assessments have focused on joint loading
in static postures. However, epidemiologic studies have shown that three-dimensional
dynamic motion is associated with an increased risk of occupational injury and
illness. The Biodynamics Lab has developed a unique research program that focuses
on the study of occupational joint loading under realistic dynamic motion conditions.
The program’s goal is to obtain a better understanding of how much exposure to
realistic risk factors is too much.

Snook’s Psychophysical Tables

These tables are based on psychophysical data and provide the maximum acceptable
weights and forces for various common tasks including lifting and lowering weights,
pulling and pushing forces, and carrying objects. Values are given for different lift
heights, number of lifts per minute, and percentiles of male and female populations
capable of the task.

Appendix D Improvement Evaluation “Tool”
As you evaluate possible improvement options, keep in mind the requirements that
are most important in your particular workplace. Then, ask the following general
questions for each improvement option under consideration:

Will this improvement:
• Reduce or eliminate most or all of the identified risk factors?
• Add any new risk factors that have not been previously identified?
• Be affordable for our organization (e.g., is there a simpler, less expensive
alternative that could be equally effective)?
• Affect productivity or efficiency?
• Affect product or service quality?
• Provide a temporary or permanent “fix”?
• Be accepted by employees?
• Affect employee morale?
• Be able to be fully implemented (including training) in a reasonable amount of time?
• Affect the rate of pay or any collective bargaining agreements?

If you are thinking about new equipment for handling material, additional questions
need to be answered. An evaluation will help to ensure that you choose the most
appropriate piece of equipment to improve the “fit” between the task and the worker.
For each improvement option under consideration, ask yourself if this particular piece
of equipment will:
• Reach far enough to cover the work area?
• Handle the weight and shape of the product?
• Re-orient the load as needed for production (e.g., to empty or pour contents)?
• Be easy to load or unload?
• Require much force or energy to push it, steer it around corners, or stop it
at the destination?
• Be heavy or large?
• Handle the load in a safe and controlled manner? Is the load held securely and is
it well balanced? Will cables or chains allow too much movement compared with
rigid links?
• Allow an adequate field of view for the operator?
• Slow workers down too much to meet production requirements?
• Interface with existing equipment and structures? Will weight-bearing columns,
shelving, or other structures block the movement of the equipment?
60 • Need an additional power supply beyond what is currently in place?
