Hydraulic Lifting Platform
Hydraulic Lifting Platform introduce
Lifting platform is a kind of lifting machine for vertical transportation of people or things. It also refers to the equipment for vertical transportation in factories, automatic warehouses and other logistics systems. The lifting platform is often also equipped with various flat conveying equipment as a connecting device for different height conveying lines. Generally used hydraulic drive, so called hydraulic lifting platform. In addition to being used as different heights of goods transport, it is widely used in the installation and maintenance of high altitude operations. Lifting platform free lifting characteristics have been widely used in municipal maintenance, docks, logistics center cargo transportation, construction and decoration, etc., installed with a car chassis, battery car chassis, etc. can walk freely, the working height space has also changed, with light weight, self-propelled, electric start, self-supporting legs, simple operation, large operating surface, can cross the barrier for aerial work, such as 360 degrees of free rotation advantages.
Lifting platform equipment working principle.
Hydraulic oil from the vane pump to form a certain pressure, through the oil filter, flame-proof electromagnetic reversing valve, throttle valve, hydraulic control check valve, balance valve into the lower end of the liquid cylinder, so that the piston of the liquid cylinder upward movement, lifting heavy objects, the upper end of the liquid cylinder back to the tank through the flame-proof electromagnetic reversing valve, its rated pressure through the relief valve for adjustment, through the pressure gauge to observe the pressure gauge reading value.
The piston of the liquid cylinder moves downward (both the weight drops). Hydraulic oil enters the upper end of the cylinder through the explosion-proof electromagnetic reversing valve, and the lower end of the cylinder returns to the tank through the balance valve, liquid-controlled check valve, throttle valve, and explosion-proof electromagnetic reversing valve. In order to make the weight fall smoothly, safe and reliable braking, set up a balance valve on the return oil circuit, balance the circuit, maintain pressure, so that the speed of fall does not change by the weight, the throttle valve to adjust the flow, control the lifting speed. In order to make the brake safe and reliable, to prevent accidents, increase the liquid-controlled check valve, that is, hydraulic lock, to ensure that the hydraulic line accidental burst can be safe self-locking. Installed overload acoustic alarm, to distinguish between overload or equipment failure.
