Bridge crane Currently, this is the most widely used and extensively applied type of crane, commonly found in indoor and outdoor warehouses, factory buildings, docks, and open-air storage yards. The lifespan of specialized machinery equipment primarily depends on the quality of the equipment itself, followed closely by how well it is maintained—maintenance can be categorized into daily upkeep, monthly servicing, and annual inspections. For detailed maintenance guidelines, refer to the following methods:
1) Bridge crane exterior maintenance: Clean off surface dust and inspect for cracks or weld fractures.
2) Vehicle Maintenance: Inspect the transmission shaft bracket, gearbox, couplings, and shafts/keyways for any looseness; tighten them if necessary. Also, check and adjust the brake wheel clearance to ensure it is uniform, responsive, and reliable.
3) The maintenance of the gearbox primarily involves checking for oil leaks.
4) Elevator and Hoist Maintenance: ① Inspect the wire rope, hook, and pulley for safety and reliability; replace them immediately if wear exceeds the specified limits. ② Check and adjust the brake mechanism to ensure it operates safely, smoothly, and reliably.
5) Inspection and Maintenance of Steel Cables: Pay close attention to conditions such as wire breaks, wear, kinks, and corrosion. For areas with significant wear or wire breaks that haven’t yet exceeded the allowable limits, mark them clearly for focused monitoring and follow-up inspections.
6) Lubrication and Maintenance: Check the oil quality and level in all components, and add or replace lubricants as required.
7) Bridge Crane Pulley Maintenance :The focus is on whether the groove bottom wear exceeds the standard and whether cracks are present in the cast-iron pulley.
8) Electrical Maintenance: Check whether all limit switches are sensitive and reliable; verify that all electrical components in the control box operate smoothly and reliably; inspect motors, bells, and wiring for safety and proper functionality; and ensure signal lights are working properly.
9) Check all coupling joints of the bridge crane for looseness or even "key rolling." Pay particular attention to any abnormal wear on the elastic rubber rings of the flexible pin couplings, and carefully inspect the gear teeth of gear-type couplings for signs of wear.
Daily maintenance is especially crucial for bridge cranes—beyond effectively extending their service life, it also allows for the early detection and resolution of potential safety hazards, helping to prevent accidents altogether.
