Working principle of hydraulic lifting platform:

Hydraulic oil made certain pressure vane pump, the oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, balance valve into the lower cylinder, the hydraulic cylinder piston upward movement, improve the weight, the upper cylinder oil return by the flameproof electromagnetic directional valve back to the fuel tank, the rated pressure through the overflow valve adjustment, observing the pressure gauge pressure gauge reading values.The piston of the cylinder moves downward (i.e. the weight drops).The hydraulic oil enters the upper end of the cylinder through the explosion-proof electromagnetic reversing valve, and the oil from the lower end of the cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve and flameproof electromagnetic reversing valve.In order to make the weight drop steadily and brake safely and reliably, a balance valve is set on the oil return road to balance the circuit and maintain the pressure so that the fall speed will not be changed by the weight. The throttle valve regulates the flow and controls the lifting speed.In order to make the brake safe and reliable, to prevent accidents, increase the hydraulic control one-way valve, that is, the hydraulic lock, to ensure that the accidental burst in the hydraulic pipeline can be safe self-locking.Overload acoustic control alarm is installed to distinguish overload or equipment fault.


Hydraulic lift platform is widely used in automotive, container, mold manufacturing, wood processing, chemical industry and other kinds of industrial enterprises and filling production line, meet the demand of the rise and fall of various working height, at the same time can be equipped with all kinds of mesa form (e.g., ball, roller, wheel, steering, tilting, scale), with all kinds of control mode (points, linkage, explosion-proof), are characterized by their smooth lifting characteristics of accurate, frequent start, large capacity, effectively solve all kinds of lifting operation difficulties in industrial enterprises, make the production operation.


1. The machine has light weight, good mobility and is suitable for single operation

2. Special regulating wheel device between mast posts, which can lift and lower smoothly and freely;Micro hydraulic power unit

3, compact structure, small size of transportation state, can enter the general elevator car and can pass through the door and narrow passage;4, double protection leg structure, more safe work, and can be close to the work face lifting operation;Double column aluminum alloy elevator is a new generation of products, the overall use of high strength aluminum profile refined because of the high profile strength, so that the lifting platform deflection and oscillation is minimal.Double mast structure is adopted, with large load, large platform area, excellent stability, flexible operation and convenient implementation.Its lightweight appearance allows it to maximize lift in a very small space.The lift is widely used in factories, hotels, buildings, shopping malls, stations, airports, stadiums and so on.It can be used for installation and maintenance of electric power lines, lighting appliances, elevated pipelines, etc.

Hydraulic lifting platform operating procedures: industrial hydraulic power plant

1. The hydraulic lifting platform has been repaired and debugged before delivery, and all the technical indicators have reached the design requirements. Only the ground wire needs to be connected when using it.Hydraulic electrical system does not need adjustment.

2. The platform shall carefully check the hydraulic and electrical systems before use, and shall not be used until there is no leakage or exposure.

3. When the platform is in use, the four legs should be firmly supported on solid ground (subject to the walking wheel leaving the ground). Sleepers can be used when necessary.

4. The platform can be transported by air for 1-3 times before loading operation.

5, the center of gravity of the load should be as far as possible in the center of the table surface position.

6. Movable doors at both ends of the protective railing should be closed firmly and locked before operation.
