Overhead crane inspection checklist
Overhead cranes need to be inspected by the operator. (cranes 2 image by Gudellaphoto from Fotolia.com)

Overhead cranes come in many forms. The crane can run on rails, gantries or just hang on a beam attached to a wall. Cranes can be controlled by an attached handset, from a cab or by a remote control device. No matter what style of crane, the operator must inspect it before use.

Electrical Inspection

The crane operator can easily check the electrical operation of a crane. Each crane has controls that move up and down, east and west, north and south. The control labels tell the operator which direction the crane will move once that button is pushed. Inspect the crane to ensure it moves the same direction the buttons say it will move. Another electrical part to inspect is the upper and lower limits of the crane. The upper limit stops the pulley and block from moving after it reaches its top limits; the same is true with the lower limit stop. Check to ensure the pulley and block stops in both positions.

Mechanical Inspection

A crane is made up of movable components that cause friction. This friction causes wear to the movable parts. The hooks, sheaves, pulley and stops are all parts of the crane that need inspection before every use. Visually look for excessive wear on any of these component parts and determine if the crane is safe to use. Check to see if the crane moves smoothly across the rails and that the brakes work. An experienced operator can listen to the operation of the crane as he inspects it and hear any problems.

Rope Inspection

One of the most important parts of a crane inspection is the rope inspection. Before each use, run the crane block and tackle all the way to the bottom limit and look at the wire rope. During this inspection, look for any kinks, breaks or fraying of the wire rope. If you find any of these deformities, inspect closer to ensure the damage does not affect the load capacity of the crane.

Safety Inspection

Inspect all the safety features on a crane. These will include any safety lights that go on as the crane operates. The safety stops ensure the crane will travel no farther than it is intended to travel; these stops include the upper and lower limit switches mentioned earlier. Inspect the emergency shut-off switch to ensure it works properly. Inspect any other special safety device installed on the crane.
