Riggers must be physically fit, trained in safe lifting equipment use, and able to properly signal crane operators. Rigging forms the link between the crane and load, and riggers must understand load ratings and inspection criteria for slings and hardware to ensure safety. Proper lifting techniques include using tag lines and avoiding excessive included angles when attaching slings. Riggers should inspect all equipment before each use and replace anything damaged or worn.

- 1. SAFE LIFTING
- 2. RESPONSIBILITIES OF RIGGER • To Qualify as a slinger / Bansk man, the person should be medically and physically fit (have a good eye sight, hearing) • Have been trained in the safe use of lifting equipment. Ability to select and use the lifting tackles as per load configuration. • To be able to provide necessary signals for crane operators. • To locate load in away, to ensure safety of load and working personnel. • To understand his companies, rules and regulation, color coding and certification of lifting tackle. • To be able to communicate with radio where the crane operator Is out of range.
- 3. Definition of Rigging • Rigging is part of the lifting operation which forms the link between the crane and the load. • Safe working load (SWL) is the load that can safely be lifted provided your lifting equipment is in good condition and has three(3) items marked on it i.e. • S.W.L. or WLL • Identification No. • Color code If does not have these (3) items marked on it, Change it for items that do have these (3) items marked on it.
- 4. SWL Identification No. SLING MARKING current Color code
- 5. Hardware Application When the included angle is greater than 90 degree use a shackle to attach the sling legs to the hook. Hook Inspection Hook must be removed from service when any of the following conditions exist. •Cracks, nicks or gouges • Twist exceeding 10% from plane of unbent hook. • Latch engagement, damage or malfunction. • Throat opening exceeding 15%. • Wear exceeding 10% of original dimension. • Damage from heat. •Unauthorized repairs.

- 7. Safety Precautions Check the sling before use, if any damage don't use. Higher elevation rigger should wear safety harness. Objects lifting time use tagline to avoid rotate the objects. Use proper type of slings, size of slings for the objects.
- 8. Shackle Application Shackle Application Never replace a shackle pin with a bolt. the strength of an ordinary bolt is much less than that of a shackle pin. Hardware Shackles Inspection Absence of capacity or identifying marks. Bent or distorted pin and/ or body. Nicks, gouges or cracks. Heat or chemical damage. Body spread. Reduction in diameter of pin and/ or body greater than 10% .
- 9. Sling Inspection Rigging equipment shall not be loaded in excess of its indicated recommended safe load, and shall be inspected prior to each lifting operation. In case of wire slings, the working load shall be based on the size and load chart, as marking is not practical.
- 10. Inspections shall be carried out for every lifting device or accessory before use. In addition, yearly inspection and load test shall be carried out by a competent inspection agency. Wire ropes used for slinging will not be used with sling eye formed by knotting the wire rope or the use of wire rope bolted clips.
- 11. CRANE APPLICATION Wind speed for mobile crane, Maximum from 32 / 35 km/h
