How to properly maintain the bridge crane? 

There are many things to pay attention to in the maintenance of large-tonnage overhead cranes. One of the more important points is to carry out regular cleaning. Regular cleaning can keep the overhead crane in good working condition, not only to avoid dirt all over the body, but also to prevent its internal Some parts are damaged by impurities etc.

Before cleaning the bridge crane, it is necessary to remove some impurities and sludge to ensure that the impurities on the outside and in the gap are removed. After cleaning the impurities on the bridge crane, you can also wash it with an appropriate amount of water. Strict anti-rust treatment should be carried out on the overhead crane, so as to maintain the good appearance and overall performance of the crane.

Regular cleaning of overhead cranes is the key to improving the operation quality and service life of hoisting machinery.

In addition to regularly cleaning the outside of the bridge crane, always pay attention to the upper end of the runway girder and girder of the bridge crane to ensure that there are no foreign objects, dirt or debris on the crane runway girder and girder that may hinder the progress of the bridge crane.

When the bridge crane is running, dust or debris is often scattered on the track surface and surrounding areas of the crane, which affects the safe operation of the bridge crane. Not only can these foreign objects, dirt, or debris damage equipment (including wheels, axles, and bearings), they can also derail the wheels, causing them to fall off the runway or frame, creating a hazard.

While it's mounted in front of the wheels, make sure they touch (and knock off) any dirt, debris, or other objects they may encounter before the wheels do.

However, there will still be some dirt, debris or other objects that cannot be avoided (the existing rail cleaners for large wheels are all made of angle steel, and the distance between the bottom of the angle steel and the rail tread is about 10mm), so be sure to check the runway regularly. rails and girders to ensure they are free of foreign objects, including the rails themselves.

Every year, rail cleaners should be carefully inspected to ensure they are not bent, damaged or broken. In addition, each sweep rail connection to the bridge end truck and trolley should be inspected to verify that they are properly aligned and securely attached. Any damage or misalignment should be reported immediately to the supervisor or crane owner and required maintenance or replacement performed promptly.
