How is MORN Scissor Lift Working

Hydraulic MORN scissor lift table is mainly used to transfer goods between different levels. Hydraulic system with heavy loading capacity and smooth working features. The lift table could be equipped with Operate Buttons at each floor, even on the working platform, it could be controlled at each level. Scissor structure is stable, it is easy and convenient to do installation & maintenance. So it is an ideal material handling equipment for short distance. Furthermore, scissor lift platform could be customized according to actual application and individual request, equipped with different Optional Configuration, to fit under each specific circumstance

Working Principle of Hydraulic Lifting Platform from MORN LIFT

When the motor start, it will generate pressure to oil tank, the oil will be pressed  into the cylinder through the oil pipe. The cylinder will stretch accordingly, and will raise the platform up. When lift touch the limit switch, the power will be cut off. At this time, platform is at the max. height, and stop raising. When platform lowers down, the solenoid valve on motor will open, which allow the hydraulic oil go back to the oil tank. When the lift touch the limit switch, power will be cut off. At this time, platform at the min. height, and stop decline.


The hydraulic oil pump station generate a certain pressure by the vane pump station, and enters the lower end of the cylinder through the oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve, so that the piston of the cylinder moves upwards and lifts the weight. The oil return from the upper end of the hydraulic cylinder is returned to the fuel tank through the flameproof electromagnetic reversing valve, and its rated pressure is adjusted through the overflow valve, and the pressure gauge reading value is observed through the pressure gauge.


The piston of the hydraulic cylinder moves downward (that is, the weight drops). The hydraulic oil enters the upper end of the cylinder through the explosion-proof electromagnetic reversing valve, and the return oil from the lower end of the cylinder returns to the tank through the balance valve, hydraulic control check valve, throttle valve, and explosion-proof electromagnetic reversing valve. In order to make the heavy objects fall smoothly and brake safely and reliably, a balance valve is installed on the oil return line to balance the circuit and maintain the pressure so that the descending speed is not changed by the weight. The throttle valve adjusts the flow rate and controls the lifting speed. In order to make the brake safe and reliable, and prevent accidents, a hydraulic control check valve, namely hydraulic lock, is added to ensure that it can lock itself safely when the hydraulic pipeline bursts accidentally. An overload sound-activated alarm is installed to distinguish overload or equipment failure.


MORN hydraulic lifting platform is widely used in various industrial enterprises and production lines such as automobiles, containers, mold manufacturing, wood processing, chemical filling, etc., to meet the lifting needs of different working heights, and can be equipped with various table tops (such as balls, rollers, Turntable, steering, tilting, telescopic), combined with various control methods (division, linkage, explosion-proof), has the characteristics of stable and accurate lifting, frequent starting, large load capacity, etc., effectively solving various difficulties in lifting operations in industrial enterprises, making Production operations are effortless.
