The maximum bearing capacity is 100 tons, realizing multi-point control and interactive interlocking of upper and lower floors to achieve safe use; The lifting height is high, and the side oil cylinder or double measuring oil cylinder is adopted, which is stable in operation, noiseless, convenient in maintenance and long in service life; Manual descent and emergency stop buttons for power failure are convenient, fast and practical; The landing door can be connected, and the inside and outside of the plant can be poked open, which is convenient and space-saving; It is especially suitable for 2-6 floors of steel structure plant, and can be used inside and outside; The pump station adopts imported pump station and domestic pump station. If the speed requirement is too high, the domestic customized pump station is adopted to meet the ideal delivery requirements. The oil cylinder and seal are imported parts to solve the problem of unstable oil pressure and oil leakage of parts. The development of elevators is at a peak. Because most manufacturers or individuals choose multi-storey buildings to improve the utilization rate of the site, a device is also needed to facilitate the lifting and lowering of goods. Because of the high cost and low bearing capacity of ordinary elevators, they are not suitable for loading dozens or hundreds of tons of goods, so hydraulic elevators with high bearing capacity have been developed to assist production and goods transportation. The elevator is both safe and has huge load capacity, and it is easy to maintain, which makes this special industry develop faster.
