Rail freight elevator hydraulic lift a non-hydraulic scissor lift freight elevators, is the use of a very wide range of goods vertical transportation equipment. It is driven by a motor pump, relying cylinder drive chain driven hydraulic lift heavy lift freight elevator level, the use of a hydraulic lifting power, with carrying capacity, smooth movements and other characteristics, widely used in the vertical transport of goods between the high-rise buildings. Rail freight elevator hydraulic lift characteristics of rail freight elevator hydraulic lift heavy-duty chain drive, oil rope for insurance, rail freight elevator hydraulic lift with hydraulic oil pipe explosion, with a safety device to prevent overloading with multiple limit switches protection, set There are open power protection devices with leakage protection device with multi-story interactive chain, so the safety factor of rail freight elevator hydraulic lift is much higher than the average freight elevators; rail freight elevators using hydraulic lift cylinder and chain drive, moving parts less so than the maintenance of hydraulic scissor lift freight elevators less; rail freight elevators compact hydraulic lift, used scissor hydraulic bearing ratio will be less than the life of its hydraulic scissor lift freight elevators much longer ; rail freight elevator hydraulic lift hydraulic transmission, so load is relatively large; transfer rail freight elevator hydraulic lift height than the hydraulic scissors lift freight elevator is much higher, up to tens of meters, stability than the hydraulic scissors lift freight elevators good; rail freight elevator hydraulic lift fell adopt its own weight and cargo weight, and therefore to the economy than ordinary freight elevators run; hydraulic lift freight elevators using plc programmable controller, to achieve intelligent control and display, while the line is simple, low failure rate. (A) in accordance with the structure of the different sub-lift: scissor lift (fixed scissor lifts, mobile lifts), sets of cylinder lift, aluminum (column) lift, Boom Lift (folding arm replacement ), cylinder straight top-lifting device, rail chain lifts (elevators, freight elevators), cable hydraulic lifting device.
