The working characteristics of the crane are intermittent motion, that is, the corresponding mechanisms for taking material, moving, and unloading in a working cycle work alternately. Each mechanism is often in the working state of starting, braking and running in forward and reverse directions. Cranes can be divided into: bridge cranes: because its two ends are located on the supports of tall cement columns or metal rail beams, the shape is like a bridge (overpass).

Cranes mainly include hoisting mechanism, running mechanism, luffing mechanism, slewing mechanism and metal structure. The hoisting mechanism is the basic working mechanism of the crane. Most of it is composed of a hoisting system and a winch, and some lifts heavy objects through a hydraulic system. The running mechanism is used to move heavy objects longitudinally and horizontally or adjust the working position of the crane, and is generally composed of a motor, a reducer, a brake and a wheel.

Due to the frequent use of crane accessories, and the environment may be relatively humid, this will cause the appearance of rust. In this case, it will not only affect its appearance, but also affect its performance. To avoid this If such a situation occurs, you can do a good job of painting. Let's briefly talk about the anti-rust measures for lifting accessories using paint.
