13 Dec Overhead Crane Safety – Safe Lifting and Load Handling

Overhead Crane Safety – Safe Lifting and Load Handling

Overhead crane safety is essential whenever cranes are used to lift and move heavy materials through shops, warehouses, manufacturing facilities, or other work areas. A suspended load can create serious struck-by, caught-between, and crushing hazards for both the operator and nearby workers.

Only trained and authorized employees may operate overhead cranes. Operators must understand the crane controls, rated capacity, inspection requirements, warning devices, and safe operating procedures for the equipment they use.

Before Operating an Overhead Crane

Before beginning work:

• Inspect the crane and applicable components as required before use.
• Check hooks, wire rope or chain, controls, brakes, limit devices, and other safety devices for obvious defects.
• Inspect slings and rigging equipment before use.
• Verify that the load does not exceed the rated capacity of the crane, hoist, or rigging equipment.
• Confirm that the load can be properly balanced and securely rigged.
• Check the intended travel path for workers, equipment, structures, and other obstructions.
• Make sure the operator has a clear view of the load and travel path or uses an appropriate signal person when necessary.
• Report defects and remove unsafe equipment from service as required.

Never operate a crane when required safety devices are missing, damaged, bypassed, or malfunctioning.

Lifting and Moving Loads

Before lifting, make sure the hook is positioned over the load to minimize swinging.

• Use only properly rated and inspected rigging.
• Make sure the load is balanced and securely attached before raising it.
• Take up slack gradually and make a controlled test lift when appropriate.
• Lift, lower, and travel smoothly; avoid sudden starts, stops, or changes in direction.
• Keep the load under control and avoid unnecessary swinging.
• Never exceed the crane’s rated capacity.
• Never use the crane to side-pull or drag a load unless the equipment is specifically designed and approved for that purpose.
• Use taglines when necessary and safe to control the load.
• Never ride on a load, hook, sling, or other lifting device unless equipment is specifically designed and approved for personnel lifting.

Stay Clear of Suspended Loads

A suspended load should always be treated as a serious hazard.

• Never stand, walk, or work beneath a suspended load.
• Do not move loads over employees whenever it can be avoided.
• Keep employees clear of the load’s travel path and landing area.
• Keep hands and other body parts away from pinch and crush points.
• Never place yourself between a suspended load and a fixed object.
• Use established warning signals or communication methods to alert workers before crane movement.
• Stop crane movement if personnel enter the danger area.

Workers should never assume an operator can see them simply because they can see the crane.

Controls and Communication

Crane controls should be clearly identified, and operators must understand the function and direction of each control before use.

When a signal person is required, the operator and signal person must understand the signals being used. If communication is lost or a signal is unclear, stop crane movement until communication is restored.

The operator must obey a stop signal regardless of who gives it.

Pinch Points and Moving Equipment

Overhead cranes contain moving components that can create caught-between and entanglement hazards.

• Stay clear of bridge and trolley travel areas.
• Keep hands and feet away from pinch and crush points.
• Secure loose clothing, jewelry, and long hair when exposure to moving equipment exists.
• Never bypass guards, limit switches, interlocks, or other safety devices.

Maintenance and Lockout/Tagout

Maintenance, adjustment, or repair work can expose employees to electrical, mechanical, gravitational, and other hazardous energy.

Before performing work that requires hazardous energy control:

• Follow the company’s lockout/tagout procedures.
• De-energize and isolate applicable energy sources.
• Lower or otherwise secure suspended components and loads.
• Prevent unintended bridge, trolley, or hoist movement.
• Verify isolation before beginning work.
• Restore guards and safety devices before returning the crane to service.

Only trained and authorized personnel may perform maintenance or repairs.

When the Crane Is Not in Use

When crane operations are completed:

• Do not leave a suspended load unattended.
• Lower and safely land the load.
• Raise the hook to an appropriate location where it will not create a hazard.
• Place controls in the designated off or neutral position.
• Follow established shutdown and parking procedures.

Remember

Overhead crane safety depends on the operator and everyone working nearby. Inspect the equipment, know the capacity, rig loads correctly, maintain communication, and keep everyone away from suspended loads and pinch points.

Never place yourself beneath a suspended load or between a moving load and a fixed object.
