Common fault handling methods of single beam bridge crane

Single beam bridge crane is an indispensable equipment in modern industrial production. It is widely used in the lifting, transportation, loading and unloading, installation and other operations of various goods. It plays a great role in improving labor productivity. In the process of using bridge crane, it is inevitable to encounter some fault problems and can not operate normally. The following are the common treatment methods for cranes:

1.  Braking failure: maintenance of electrical components; Replace the brake bushing; Replace the main 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 achieve the average clearance. When driving, the lining can remove the brake wheel; Replace the auxiliary spring; Repair the working surface of the brake wheel.
4.  Unstable energy moment: adjust the concentricity to make it consistent.
5.  Hook group falling: repair the limit device immediately; Overload is strictly prohibited; Replace the rope with a new one.
6.  Crooked hook head and inflexible rotation: replace the thrust bearing.
7.  Periodic jitter and noise of reducer: change 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 the 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 rail height difference.
10.  Large wheel rail gnawing: check the key connection state of the transmission shaft, the meshing state of the gear coupling and the connection state of the bolts of each part, remove the excessive clearance and make the transmission at both ends coordinated; Adjust the accuracy of the wheel device: adjust the large lane track L
11.  Motor overheating: slow down the starting frequency of the crane, slow down the load or replace the motor according to the type of task.
12.  Vibration during motor operation: replace damaged bearings.
13.  Master the jammed state of the controller in the task: change the contact.
14.  Reasons why the main contactor does not draw: the power supply has no voltage, the fuse is open, the main handle is not in the zero position, the emergency switch and interlocking contact are not closed, and the coil of the main contactor is burned.
15.  Reasons for trolley one-way operation: poor contact of limit switch and disconnection of connecting section; The corresponding interlocking contact in the motherboard is in poor contact or disconnected; Poor contact of the reverse coil or normal closing contact, the other side of the auxiliary.
16.  Reasons why the auxiliary hook cannot be picked up: the limit switch is disconnected, the contact is poor, and the sliding wire is broken.

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