Features of rail type hydraulic freight elevator

The rail type hydraulic freight elevator is a non-scissor type lifting platform, and it is called a rail type lifting platform because it adopts a rail chain type lifting structure. The rail-type lifting platform is mainly used in places where pits cannot be dug, and there is no need for a machine room above the hoistway, which greatly saves construction costs. The rail-type lifting platform has stable lifting, stable operation, low noise, multi-point control and long service life due to its unique rail chain structure. The product is mainly used for cargo transmission between the second and third floor industrial plants, restaurants, and restaurants. It has various forms such as single column, double column, and four column. It has stable movements and simple and reliable operation. It is the most ideal hydraulic pressure to replace electric hoist Lifting freight elevator equipment . 3 Advantages of Hydraulic Freight Elevator Editing Safety and Stability Advantages In addition to the safety devices of traditional traction elevators, hydraulic elevators are also equipped with:
(1) Overflow valve: It can prevent the system pressure from being too high during upward movement. (2) Emergency manual valve: When the power fails, the car can be lowered to the nearest floor emergency position to open the hall and car door, so that the passengers can get out safely Car (3) Manual pump: when the system fails, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position;
(4) Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and falls, it can automatically cut off the oil path to stop the decline.
(5) Oil tank oil temperature protection: When the oil temperature in the oil tank exceeds the standard setting value, the oil temperature protection device generates a signal to suspend the elevator, and the elevator can be started only after the oil temperature drops. Civil engineering advantages (1) No machine room is needed above the hoistway, and the top floor can be installed above 3.5 meters.
(2) The machine room can be set within a range of 15 meters in the radius of the hoistway, occupying an area of ​​only 3-4 square meters.
(3) The hydraulic elevator is not equipped with a counterweight device to improve the utilization rate of the shaft area.
(4) The load and load of the hydraulic elevator directly act on the foundation pit through the oil cylinder, the strength of the shaft is low, and the brick structure or brick-concrete structure shaft can be used. Advantages of operating costs (1) Low failure rate: Due to the use of advanced hydraulic systems and good control methods, the elevator operation failure rate can be approached.
(2) Low power consumption: when the hydraulic elevator goes down, it is driven by the pressure generated by its own weight, which greatly saves energy.
