Cranes, Derricks, and Rigging

Cranes, derricks, and hoists are pieces of equipment used to lift heavy loads. They are commonly used in construction and clean-up operations.

Some dangers related to cranes, hoists, and derricks are obvious. For example, an improperly balanced load could fall and injure employees. Always observe the following guidelines:

• Never hoist, lower, or travel while an employee is on the load or hook.
• Never carry loads over people.
• Never use a ladder when hands are occupied with other encumbrances.
• Lower (do not carry) anything that cannot be placed in pockets or belts while going down a ladder.
• Always store personal items in crane cabs (never leave items out where they can impede operation or cab access).
• Place tools, oil cans, and other articles in the tool box (never leave loose in the cab).
• Make sure fire extinguishers meet all requirements.
• Covers or guardrails must be present to protect workers from hazards (such as open pits, tanks, vats, and ditches).
• Develop safe communication operation systems whenever any part of a crane/derrick may be within the working radius of another crane/derrick.

Always make sure that you are using the proper equipment by paying attention to the following:

• Required clearance levels
• Load ratings
• Load handling instructions
• Inspections (for comprehensiveness and frequency)
• Manufacturer guidelines
• Maintenance schedule compliance
