Operation principle and installation environment of rail type lifting freight elevator
Rail-type lifting freight elevator is a non-scissor type hydraulic lifting mechanical equipment. It is used for the goods transmission between the second and third floors of industrial plants, restaurants and restaurants. The height is 150-300mm, suitable for the work place where the pit can not be excavated. And there is no need for an upper lifting point, and the form is diverse (single column, double column, four column). The chain rail type lifting freight elevator runs smoothly, the operation is simple and reliable, and the goods transmission is economical and convenient.
The operating principle of the rail-type lifting freight elevator is because of its hydraulic power, so its load capacity is large, and it can achieve layered control between floors. The side oil cylinder or double side oil cylinder is adopted. , The oil cylinder works upward under the pressure effect of the hydraulic oil, driving the chain upward. The chain is fixed on the cargo table to make the cargo table rise; under the effect of the self-weight of the table when descending, the hydraulic oil of the oil cylinder is returned to the oil tank through the solenoid valve, so that the table falls smoothly.
The rail-type lifting freight elevator has lower requirements for the installation environment, does not require deep excavation of the foundation, and can be installed under the condition of less space, and does not require a machine room above the hoistway, which is convenient for repair, strong in stability, and saves space. Compared with elevators and freight elevators, its cost is relatively low, which has become one of the important reasons why many customers like it.
The failure rate of the rail type lift freight elevator is low: because the advanced hydraulic system is adopted and the control method is outstanding, the elevator operation failure rate can be as low as possible. Low power consumption: When the hydraulic elevator goes down, it is driven by the pressure generated by its own weight, which greatly saves energy.
Only need to dig a dozen centimeters of pits to ensure the convenience of goods in and out, and facilitate the installation and use of equipment.
Hydraulic cylinders, special heavy chains, wire ropes, and multiple maintenances ensure the safety of equipment operation and use.
