What is the operation process of an overhead crane?

All overhead crane operators must be familiar with the starting direction of operation buttons, the functions of various safety devices, and the correct methods of hanging and bundling. Otherwise, operation is prohibited. Before work, inspect the overhead crane and lifting tools (such as hooks, lifting rings, wire ropes, etc.) to ensure they are safe and reliable. Operation is only permitted when no issues are found. Ensure that the object to be lifted is securely and stably hung before hoisting. During lifting, it is prohibited to use more than two movements simultaneously or to pull or drag obliquely.
When operating overhead cranes in the workshop previously, I always prioritized safety procedures. Before starting, I would consistently check whether the hooks were secure, inspect cables for wear, and verify the proper functioning of limit switches. The operating environment needed to be cleared, with no debris on the ground to avoid collisions with obstacles during movement. Wearing a safety helmet and anti-slip shoes was mandatory. After activating the controller, I would first test the no-load operation to ensure smooth travel and trolley movement, only proceeding with lifting loads after confirming everything was normal. When using it to lift engines or transmissions during automotive repairs, I made sure the lifting position was properly aligned and operated with slow, controlled movements to avoid sudden stops. Throughout the operation, I constantly monitored load stability and would immediately pause to make adjustments if any deviation occurred. After completion, I would reset the equipment and report any abnormalities. This procedure prevented accidents, which is particularly crucial in automotive services since crane-related incidents involving heavy loads can easily cause injuries or vehicle damage. Remember, safety comes first – never skip inspections for the sake of convenience.
I personally find operating the overhead crane quite straightforward—it's a step-by-step process without confusion. First, turn on the power switch and confirm the controller responds normally. Then, control the movement directions of the trolley and bridge as needed, such as forward, backward, or rotation. When hoisting a load, I secure the hook properly, slowly lift it to the desired height, and then smoothly move it to the target position for lowering. In the auto repair shop, I often use it to handle wheels or chassis components, maintaining a steady speed to minimize sway. During operation, I keep a close eye on the load height and surrounding environment to ensure no collisions with people or equipment. After finishing, I turn off the power and make a brief record. This workflow is simple and easy to learn, suitable for beginners—with a few more practice sessions, one can become proficient. The key is not to rush, staying steady to avoid mistakes.
