Guide-rail hydraulic lift freight elevator, a non-scissor type hydraulic lift freight elevator, is a very widely used vertical transportation equipment for goods. It uses a motor to drive an oil pump and relies on an oil cylinder to drive a heavy-duty chain to drive the hydraulic lifting freight elevator to move horizontally. Due to the use of hydraulic pressure as the lifting power, it has the characteristics of large load capacity and smooth lifting. It is widely used in vertical transportation of goods between high-rise buildings. Features of the guide rail type hydraulic lift freight elevator The guide rail type hydraulic lift freight elevator uses heavy-duty chain transmission and oil wire ropes for insurance. The guide rail type hydraulic lift freight elevator uses hydraulic explosion-proof oil pipes and is equipped with safety devices to prevent overloading. It is equipped with multiple limit switch protection and has door-opening power-off protection. The device is equipped with a leakage protection device and a multi-story interactive chain. Therefore, the safety factor of the guide rail hydraulic lift freight elevator is much higher than that of ordinary freight elevators. The guide rail hydraulic lift freight elevator uses oil cylinders and chain transmission and has fewer moving parts, so the maintenance workload is smaller than that of the scissor type. Hydraulic lifts require fewer loads. Guide-rail hydraulic lifts are compact and use fewer bearings than scissor-type hydraulic lifts. Their service life is much longer than scissor-type hydraulic lifts. Guide-rail hydraulic lifts use hydraulic transmission, so their load capacity is relatively large. The transmission height of the rail-type hydraulic lift freight elevator is much higher than that of the scissor-type hydraulic lift freight elevator, and the stability is better than that of the scissor-type hydraulic lift freight elevator. The economical hydraulic lift freight elevator uses a programmable controller to realize intelligent control and display, while the circuit is simple and the failure rate is low. According to the different lift structures, it is divided into scissor lifts (fixed scissor lifts, mobile lifts) cylinder-type lifts, aluminum alloy (column) lifts, curved arm lifts (replacements of the folding arm type), cylinder straight top lifting device guide rails Chain lift (elevator cargo lift) steel cable hydraulic lifting device
