Overhead Crane And Gantry Crane Operation

Hoist operators must inspect equipment daily before use.

Do not operate a crane or hoist if limit switches, steel ropes, chains or other components are worn or in disrepair.

Replace nylon or web slings immediately if excessively worn.

Associates in the direction of travel should be warned to move and remain clear of a lifted load at all times.

Loads should not be suspended over personnel below.

Under no circumstances may anyone ride the hook or load.

Directional movement should be made smoothly and deliberately. Avoid rapid movements in any direction.

Do not exceed the rated load capacity of the crane, hoist,chain, cable, slings, or other component.

Slings, load chains and other lifting devices must be fully and securely seated in the hook before moving a load. Remove slack from the sling, chain, or cable before lifting a load.

Use the following practices to avoid swinging loads:

1.  Locate the hoist directly above the lifting point of the load before lifting.
2. Lower loads directly below the hoist.
3. Keep hoisting ropes vertical. Do not pull or push the load.
4. Maintain two full wraps of cable on the hoisting drum.

When lifting loads at or near capacity, test the hoist brakes by returning the master switch or push button to the “OFF” position after raising the load a few inches off the floor. If the brakes do not hold, lower the load to the floor slowly and do not operate the crane. Report the situation immediately and do not use until repaired.

Ensure that all loads are lifted high enough to clear obstructions before moving the bridge or trolley. Whenever possible, maintain a minimum clearance of one foot above loads and to the sides. Raise the load only to the height necessary to clear lower objects.

Never pull a hoist by the cable.

Never leave the controls unattended while a load is suspended. If it becomes necessary to leave the controls, lower the load to the floor.

Familiarize yourself with the location of the disconnect switch.

If loss of electrical power occurs, place controls in the “OFF” position to prevent unexpected start-up upon restoration of power.

Disconnect power to a hoist that is unsafe or in need of repair. Arrange to have the disconnect switch locked and the control panel tagged with an “Out Of Order” or “Do Not Operate” tag. Never operate a hoist that has been tagged with an “Out Of Order” or “Do Not Operate” tag.
