Routine Maintenance Of Electric Bridge Cranes in Manufacturing Industry

Routine maintenance of electric bridge cranes in manufacturing industry

The crane is a kind of machinery that is easy to wear and tear. Because it is often used in production operations, it is necessary to pay attention to the maintenance of the electric bridge crane.
The following is a brief introduction to the daily inspection items of the main structural components of the 10 ton electric bridge crane.

First check whether the reducer of the electric bridge crane is leaking oil.
If there is abnormal sound in the box, open the box cover to check. It is usually caused by bearing damage, excessive meshing clearance, severe tooth surface wear and other reasons. Check the function and condition of the electric overhead crane brakes.

The brake is an important part of the 15 ton electric bridge crane, which directly affects the precision and reliability of each organization. Therefore, it is necessary to carefully check the braking condition of the lifting luffing mechanism, observe the opening of the brake shoe and the wear condition of the brake leather of the friction element.
For band brakes, pay attention to check whether there are cracks in the rear lining of the brake band, whether the brake transmission is flexible, whether the brake frame is intact, and whether the elasticity of the main and auxiliary springs meets the requirements.

Check out Electric Single Girder Overhead Crane Wire Rope.
The inspection of the wire rope should focus on observing the fracture, wear, kink and corrosion of the wire rope. For steel wire ropes that are seriously worn or broken but do not exceed the standard position, they should be marked and re-inspected.
Pay attention to check whether the safety limiter of the wire rope in the reel is effective, whether the wire rope pressed on the reel is tightened, and whether the number of compression tools is appropriate.

Check out the pulleys of electric overhead traveling cranes.
The key is whether the wear of the groove bottom is overrun and whether there are cracks in the cast iron pulley. The abnormal movement of the balance wheel of the lifting mechanism pulley block is easy to be ignored.
Therefore, it is necessary to check the flexibility of rotation before installation.
Otherwise, during the installation process, the balance wheel cannot automatically adjust the length and tension of the left and right wire ropes, which increases the difficulty and operational danger of the entire high-altitude air conditioner lifting wire ropes.

Check to see if the coupling of the electric bridge crane is loose, or even a "tumbling key".
Special attention should be paid to the abnormal wear of the elastic rubber ring of the elastic pin coupling. Because the entire ring between the two rings is worn, when the error is large. If this situation arises in an ascending organization, serious accidents may occur.

The function and failure rate of lifting equipment are closely related to the daily maintenance of the crane, and the single-girder crane is no exception as a type of crane.

The protection of the single-girder crane can play the following roles:

it can ensure the good work of each component of the single-girder crane, and effectively improve the operating efficiency and safe work of the lifting equipment, because the single-girder crane is a relatively large machine. Any damage may cause the single-girder crane to fail to work normally. Therefore, only by ensuring the normal operation of the parts can we contribute to the production work of the enterprise.

It can detect potential problems in the single-girder crane in time, ensure that the connecting parts are not damaged, and avoid the impact of equipment failure on normal operation.

The maintenance of the single girder crane can effectively extend the service life of the crane. Why do some companies use cranes for more than ten years, and some companies go bankrupt in a few years.

On the one hand, the quality of the crane is a quality problem, on the other hand, it should be properly protected.
