Crane and Derrick Basics
Introduction
Moving large, heavy loads is crucial to today's manufacturing and construction industries.

New technology has been developed to achieve these challenging equipment move. Additionally, careful training and extensive workplace precautions have been developed to protect against the associated hazards.
There are significant lifting-device safety issues related to the operation of cranes and derricks. Crane and derrick operators, and other workers exposed to working cranes and derricks, need to have a good understanding of these hazards. This course is a starting point for gaining a greater understanding about cranes and derricks, their operation, and associated hazards.
OSHA's standard 1926.1400 Subpart CC - Cranes and Derricks in Construction, applies to power-operated equipment used in construction work that can hoist, lower, and horizontally move a suspended load, unless such equipment is specifically excluded from coverage.
- articulating cranes (such as knuckle-boom cranes)
- crawler cranes
- floating cranes
- cranes on barges
- locomotive cranes
- mobile cranes (such as wheel-mounted, rough-terrain, all-terrain, commercial truck-mounted, and boom truck cranes)
- multi-purpose machines when configured to hoist and lower (by means of a winch or hook) and horizontally move a suspended load
- industrial cranes (such as carry-deck cranes)
- dedicated pile drivers
- service/mechanic trucks with a hoisting device
- a crane on a monorail
- tower cranes (such as a fixed jib, i.e., "hammerhead boom"), luffing boom and self-erecting)
- pedestal cranes
- portal cranes
- overhead and gantry cranes
- straddle cranes
- sideboom cranes
- derricks
- variations of such equipment
- power shovels, excavators, wheel loaders, backhoes, loader backhoes, and track loaders
- automotive wreckers and tow trucks when used for clearing wrecks and hauling vehicles
- digger derricks used for pole work
- vehicle-mounted aerial devices used for lifting personnel
- self-propelled elevated work platforms
- telescopic/hydraulic gantry systems
- stacker cranes
- powered industrial trucks (forklifts)
- mechanic's trucks with a hoisting device
- dedicated drilling rigs
- tree trimming and tree removal equipment
- helicopter cranes
