Hydraulic lifting freight elevator

The rail-type lifting work platform is a non-scissor fixed lifting work platform, which is a new product that has only appeared in recent years. It adopts electro-hydraulic lifting. When working, the cargo platform moves vertically along the guide rail. When ascending, the electric motor drives the hydraulic oil pump to rotate at high speed, and the hydraulic oil is driven into the hydraulic oil cylinder by the action of the hydraulic oil pump. The upper sprocket drives the chain movement, and the bottom end of the chain is connected to the cargo platform, thereby driving the lifting operation platform to rise. When the lifting platform descends, through the electrical control, the lowering electromagnetic oil return valve is opened. Under the action of the lifting operation platform and the gravity of the cargo itself, the lifting operation platform naturally descends without the need of a motor.


Rail-type freight elevators are mainly used to transport goods up and down between various working floors; three- and three-story garages and underground garages, pits where excavations cannot be excavated, and top-floor heights where the required height cannot reach the required narrow spaces, Shandong Xintai will make every effort to create a highly efficient delivery platform tailored for you. The hydraulic system of the product is equipped with anti-dropping and interactive doors on the upper and lower doors. Operation buttons can be set on each floor and the work surface of the lifting platform to achieve multi-point control. The product structure is sturdy, the load capacity is large, the lifting is stable, and the installation and maintenance are simple and convenient. It is an ideal cargo conveying device for economical and practical replacement of elevators in low floors. According to the installation environment and use requirements of the lifting platform, different optional configurations can be selected to achieve better results. This product is mainly used in chemical, high temperature, high pressure, power plants, nuclear industry bases, explosives and other explosion-proof enterprises.
The maximum load is 10 tons, which realizes multi-point control, and interlocking up and down floors to achieve safe use;
● High lifting height, using side oil cylinder or double measuring oil cylinder, it runs smoothly, noiseless, convenient for maintenance, and has a long service life;
● Manual power down and emergency stop buttons for power failure, convenient, fast and practical;
● The depth of the pit is generally 15cm-30cm, and the height of the top layer is not limited. It can be customized according to the site environment;
● The landing door can be penetrated, and the inside and outside of the plant can be opened to each other, which is convenient and saves space;
● Particularly suitable for 2-3 storey steel structure workshops, which can be used both inside and outside;
● The pump station uses imported pump stations. If the speed requirements are too high, import custom pump stations are used to achieve the ideal delivery requirements.
● The oil cylinder and seal are made of imported parts, which can solve the problems of unstable oil pressure and oil leakage.
● Electrical parts are optional, (Shanghai People's Electric, Schneider, France, Siemens, Germany)
Security and stability advantages:
The hydraulic elevator is equipped with the safety device of the traditional traction elevator, and also has:
● Overflow valve: can prevent system pressure from being too high during upward movement
● Emergency manual valve: When the power fails, the car can be lowered to the nearest floor position to open the door.
● Manual pump: When the system fails, the manual pump can be operated to release high-pressure oil to raise the car to the nearest floor position;
● Pipeline rupture valve: when the hydraulic system ruptures and the car stalls and drops, it can automatically cut off the oil circuit and stop the descent
● Fuel tank oil temperature protection: When the oil temperature in the fuel tank exceeds the standard set value, the oil temperature protection device generates a signal to suspend the use of the elevator. When the oil temperature drops, the elevator can be started.
Operating cost advantages:
● Low failure rate: due to the use of advanced hydraulic systems and good control methods, the elevator operation failure rate can be minimized.
● Low power consumption: When the hydraulic elevator descends, it is driven by the pressure generated by its own weight, which greatly saves energy.
