What are the fault handling methods of bridge crane

Bridge crane is an indispensable equipment in modern industrial production. It is widely used for lifting, transportation, loading and unloading, installation and other operations of various goods. It plays an important role in improving labor productivity. In the process of using bridge crane, it is inevitable to encounter some faults and can not work normally. Common crane troubleshooting methods are listed below:

1.  Brake failure: repair electrical components; Replace the brake pad lining; Replace the main exhaust spring and adjust the brake according to the technical regulations.
2.  Brake cannot be opened: remove obstacles; Adjust the main spring to meet the specification; Adjust or replace the brake screw; Replace the coil.
3.  The brake lining smells of coke and smoke, and the lining is seriously worn: adjust the brake to reach the average clearance, and the lining can separate the brake wheel during operation; Replace the auxiliary spring; Repair the working surface of the brake wheel.
4.  Unstable energy generating torque: adjust the concentricity to make it consistent.
5.  Hook set falling: repair the lifting limiter immediately. Overload is strictly prohibited. Replace the new rope.
6.  Unstable rotation of coupler head: replace thrust bearing.
7.  Periodic jitter and noise of reducer: replace the damaged gear.
8.  The reducer vibrates on the bridge and the sound is too loud: tighten the bolts, adjust the concentricity to make it meet the specifications, strengthen the support structure and increase its stiffness.
9.  Slip when driving: adjust the up and down position of the axle, increase the wheel pressure of the driving wheel, and adjust the height difference of the track.
10.  Large wheel rail gnawing: check the key connection state of the transmission shaft, the meshing state of the gear coupling and the bolt connection state of each part, and remove the excessive clearance to make the transmission at both ends coordinated; Adjust the accuracy of wheel device: adjust the track of large lane.
11.  Motor overheating during operation: reduce the starting frequency of the crane, reduce the load or replace the motor corresponding to the task type.
12.  Motor vibration during operation: replace the damaged bearing.
13.  Host card in task: change contact.
14.  Reason why the main contactor does not pull in: the power supply has no voltage; Fuse open circuit; The main control handle is not in the zero position; Emergency switch and interlock contact are not closed; The coil of the main contactor is burnt out.
15.  Reasons for one-way operation of crane: poor contact of limit switch and disconnection of connecting line in sections; Poor contact or disconnection of corresponding interlocking contacts in the main control; Poor contact of the reverse coil or poor contact of the normally closed contact of the auxiliary on the other side.
16.  Reasons for lifting failure of auxiliary hook: lifting limit switch is disconnected, poor contact and sliding rope is disconnected.

The above are the handling methods for common faults of bridge crane. I hope it will be helpful to you. If you have relevant product requirements, please Связаться с нами at 13273721681.
