Plate chain bucket elevator in the mechanized continuous transport system is a commonly used vertical conveying equipment. Mainly used to enhance the powder, granular, small pieces of non-abrasive and abrasive materials (such as cement, coal, sand, grain, wood, ore, coke, silicate, aluminum magnesia, refractories, fertilizers , Chemicals, etc.). According to the needs of the production process, with feeder, belt conveyor, screw conveyor and other forms of transportation equipment, can be arranged into different processes to form a variety of transportation systems. Plate chain bucket elevator is generally split into parts sent to the user. Sub-drive device, the upper chassis, the middle chassis, lower chassis, traction parts, hopper several major components. Plate chain bucket elevator chassis is a frame structure, occupy a large space, the requirements of transport flat, four corners tied in a fixed position, to avoid collision with each other when transporting, trailers and hopper separate packaging shipments. A machine sometimes need to assemble dozens of chassis, technical requirements are more complex, single-section chassis is also very strict technical requirements. Stored when the shell flange must be flat, vertical floor, to avoid skew caused by the case, affecting the machine performance.
