An overhead crane or bridge crane is commonly used for loading, unloading small or heavy-duty materials. It consists of the bridge, traveling mechanism, lifting mechanism, and electric parts. Overhead crane safety is closely related to many factors, such as operation habit of operators, crane quality, and crane accessories, etc. Each factor can greatly impact the crane safety. To avoid accidents while operating an overhead crane, it is vitally significant for operators to learn some tips.
Essential safety tips for overhead crane operation
- It is important and significant for operators to learn the operation manual and trained enough before operating a crane.
- Make sure the crane suitable for the planned hoisting project. Ensure it has enough span length and capacity.
- Daily inspection of the crane before use. Make sure each part or accessory of the crane is in good condition.
- Loading and unloading items smoothly. Make sure the stability or minimize load swing of cranes.
- Do not leave the crane(or the load) unattended when the load is suspended.
- It is not allowed that other personnel operate the crane, use tagging and lockout procedures.
- Do not lift loads over anyone. Warn all people in the load lift area before starting the lift, and ensure that the path of the load is clear of obstructions and persons.
- Before loading, lift the crane above the load to prevent the load from swinging.
- Keep fingers and hands from being trapped when slack is taken out of a sling. Step away before the load is started.
- Choose the right sling for each lift. Do not use defective or damaged slings. Do not splice broken slings. Inspect slings and other rigging hardware before use for the stretch, wear, or other damage.
- Set loads down on blocking, never directly on a sling. Do not push or pull loads out from under the hoist.
- Secure unused sling legs. Do not leave loose materials on a load or drag slings being hoisted.
- Only qualified or experienced overhead or gantry crane operators can use a crane.
- Ensure the hook is high enough to avoid accidents before moving a bridge or a trolley.
- Frequent inspection of the control systems, brakes, limit devices, operating mechanisms, etc.
