Composition of a stationary scissor lift

The stationary scissor lift is a special hydraulic lift used for transporting goods between building floors. The loading capacity of the stationary scissor lift can vary from 100 kg to 30 tons depending on the height of the lifting platform, and the height of the lifting platform can be customized according to user needs.

Scissor lift is a kind of lift. The working principle of scissor lift is similar to or the same as the working principle of scissors, except that the manual drive is changed to the cylinder drive, and then, again With some guiding devices, a scissor lift table and its working principle can be formed. The scissor lift has a scissor mechanical structure, which enables the lifting platform to have a higher stability, a large working platform and a higher load-bearing capacity, so that the high-altitude operation range is larger, and it is suitable for multiple people to work at the same time. It makes work more efficient and safer.

--The rising process of the scissor lift table:

In the hydraulic system of the scissor lift, when the hydraulic oil forms a certain pressure through the vane pump, it enters the lower end of the cylinder through the oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control check valve, balance valve and other components , And at the same time make the piston of the oil cylinder move upward, so as to achieve the purpose of rising the table.

--The descending process of the scissor lift table:

When the piston of the cylinder moves downwards, the hydraulic oil enters the upper end of the cylinder through the explosion-proof electromagnetic reversing valve, and the oil return from the lower end of the cylinder passes through the balance valve, hydraulic control check valve, throttle valve, and explosion-proof electromagnetic reversal The valve returns to the tank.

In order to ensure the safety and stability of the falling of the heavy objects, the lifting platform is equipped with a balance valve on the oil return path to balance the pressure between the circuits, so that the speed of the table surface does not change due to the change of the weight. In order to prevent accidents, the hydraulic system of the lifting platform is also specially added with a hydraulic control one-way valve, which can safely self-lock when the hydraulic pipeline explodes accidentally. At the same time, the purpose of installing an overload alarm is to prevent overloading the equipment from causing safety accidents.

The electric control component of the scissor lift is to control the rotation of the motor by operating the button in the electric box, so as to realize the lifting, lowering, and pause functions of the lifting platform.
