As we all know that overhead cranes have much working pressure. So if we want to ensure the service life of our bridge cranes, what need we do? Today Nucleon crane's engineer will tell us that we should do as the following:
1). The appearance of the bridge crane: sweep the exterior thoroughly so that there will be no dust and no yellow robes. Check for cracks and open welds.
2), carts, trolleys: check and tighten the drive shaft seat, gear box, coupling and shaft, keys are loose; check and adjust the brake wheel gap to make it uniform, sensitive and reliable.
3) Check whether the overhead speed reducer of the bridge crane mainly depends on whether it leaks oil. When there is abnormal noise in the cabinet during operation, the lid inspection must be opened. Generally caused by bearing damage or gear backlash is too large, severe tooth surface wear and other reasons.
4) Lifting and hoisting: Check whether the wire rope, hook, and pulley are safe and reliable. If the wear exceeds the specified value, replace it; Check and adjust the brake to make it safe, sensitive and reliable.
5) Inspection of bridge crane wire rope. Commonly used varieties are phosphate coated steel wire ropes, galvanized steel wire ropes and smooth steel wire ropes. The inspection of steel wire ropes should focus on the observation of broken wires, wear, kinks, and rust. For some locations where wear and broken wires are more serious but have not exceeded the standards, it is necessary to do so. Markings to focus on rechecking. Pay attention to check whether the safety limiter of the wire rope in the reel is valid, whether the wire rope pressure plate on the reel is pressed and whether the number of the pressure plate is proper.
