• #2: 1926 Subpart N – Cranes, Derricks, Hoists, Elevators, and Conveyors This presentation is designed to assist trainers conducting OSHA 10-hour Construction Industry outreach training for workers. Since workers are the target audience, this presentation emphasizes hazard identification, avoidance, and control – not standards. No attempt has been made to treat the topic exhaustively. It is essential that trainers tailor their presentations to the needs and understanding of their audience. This presentation is not a substitute for any of the provisions of the Occupational Safety and Health Act of 1970 or for any standards issued by the U.S. Department of Labor. Mention of trade names, commercial products, or organizations does not imply endorsement by the U.S. Department of Labor. Other standards and references used for this presentation are as follows: Mobile Hydraulic Crane Standards - PCSA Standard NO. 2 - Power Crane and Shovel Association 2. USA Standards - Safety Code for Cranes, Derricks, Hoists, Jacks and Slings - Crawler, locomotive and truck cranes - USAS B30.5-1968

• #78: COMMONLY USED CRANES - primary examples used in this presentation Hydraulic rough terrain crane Crawler lattice boom friction crane Several significant differences between these cranes, primarily in boom hoist and load line controls. The somewhat smooth operation of the boom control adjustments on the hydraulic cranes may falsely suggest that it is simple to operate. The lattice boom friction cranes’ movement in its boom or its adjustment in load position tend to be a little jerky requiring more skill and experience to operate smoothly. Another difference is their load charts. Due to the fixed boom lengths, the lattice boom friction crane has a more simplified load chart. This requires extensive motion control and anticipation of boom movement to accurately lift or place loads. The hydraulic crane’s load charts are more extensive making them complicated due to variations in boom length, so more training in multiple charts is required The differences between these cranes are significant enough to require specific training on each type of crane. Crane operators cannot expect to be totally knowledgeable and proficient in the operation of the many diverse types of cranes available today. They cannot be expected to move from one type of crane to another without adequate education and training on specifics of each piece of equipment.
