What does the maintenance of overhead crane safety devices include? In factories, cranes and hoists are common equipment, but they are also often involved in safety accidents. Therefore, regular maintenance of hoists is essential and should be given sufficient attention. The following shares what the maintenance of overhead crane safety devices includes.

Using on-site buildings or facilities to install cranes. For example, using factory building structures to install bridge cranes. This method is often used for taller factory buildings and the installation of large bridge cranes. Using derrick crane equipment to install mobile cantilever cranes. Divided into single-column and gantry columns, it is widely used in the installation of various large and medium-sized cranes.

For the maintenance and repair of crane transmission mechanisms, carefully check whether the wire rope fixing devices of the crane meet the requirements, whether the crane hooks are worn, peeled, cracked, or twisted, whether the relevant pins and bushings are severely worn, and whether the rope grooves and rims of the pulleys are broken, worn, or cracked.

Regularly check the condition of the pulleys and maintain an appropriate gap between the pulleys and the outer contours of other objects. If the gap is too small, the cover plate will be worn by the pulley. If the gap is too large, the wire rope will loosen out of the groove or be pinched between the cover plate and the pulley rim. At the lifting balance beam and the wedge shell outlet of the closing mechanism pulley group, there is a risk of biting or cutting the wire rope. The roundness and smoothness of the wedge shell outlet should be checked frequently. If it is rough or has worn sharp edges, the rounded corners must be re-filed smooth.

The cantilever crane double-beam gantry crane jib crane is a new type of material handling equipment developed on the basis of the wall-mounted cantilever crane. The crawler device of this machine is on the cement columns in the workshop and can move longitudinally along the crawler. The electric hoist can complete horizontal movement and linear lifting along the cantilever. This machine greatly expands the working scale, makes better use of factory space, and is more ideal to use.

Hoisting machinery installation parts are indispensable mechanical equipment on hoisting machinery. During the use and operation of hoisting machinery, there will inevitably be some wear and tear on the equipment. Over time, parts will also wear out. Sometimes, problems with the quality of mechanical equipment and maintenance difficulties puzzle users.
