The disadvantage of the hydraulic lifting freight elevator is that the stroke receives the limitation of the longitudinal bending strength of the hydraulic cylinder. It is not suitable for buildings with too high. What are the differences between the elevator and the hydraulic freight elevator? The disadvantage of the hydraulic lifting freight elevator is that the stroke receives the limitation of the longitudinal bending strength of the hydraulic cylinder, which is not suitable. Too high a building is generally suitable from six to eight floors. In addition, the platform does not have a balance weight. The entire weight of the platform table needs to be absorbed by the hydraulic pressure, so the power consumption is large. During the operation of the hydraulic platform, the cylinder is in operation. When the high pressure oil is input, the platform rises; when the hydraulic oil is removed from the cylinder, the platform drops due to its own weight, so changing the flow rate of the oil supply or the oil discharge can adjust the speed at which the platform rises or falls. The quick stacking door has many functions such as heat preservation and cold preservation, insect and wind prevention, dust insulation and sound insulation. Widely used in underground parking lots, industrial plants, food, textiles, electronics, printing and packaging, automotive assembly, precision machinery, logistics and warehousing and other places.
