Belt conveyors are a kind of friction-driven machinery that transports materials in a continuous manner. They are mainly composed of a frame, a conveyor belt, rollers, a transmission roller, a tensioning device, a transmission device, etc. It can form a material conveying process from the initial feeding point to the final unloading point on a certain conveying line. It can convey both bulk materials and pieced items. Rollers are an important part of belt conveyors. During the use of belt conveyors, when rollers are worn to a certain extent or bearings are damaged, they need to be replaced. When replacing rollers, the heavy conveyor belt presses on the rollers. Since there are no auxiliary support tools, the rollers can only be removed, installed and replaced by people carrying them on their shoulders. In some areas with small spaces or heavy conveyor belts, it is necessary to use a chain to lift the belt conveyor to operate. The labor intensity is very high and the work efficiency is very low. If you are not careful, personal injury accidents may occur. There are high safety hazards and operational risks.
