Hydraulic cylinder piston downward movement (both heavy falls). -Oil explosion-proof solenoid valve into the cylinder upper end, a lower end of the hydraulic cylinder return oil through balancing valve, check valve, throttle valve, explosion-proof solenoid valve to the tank. In order to decrease the weight stable aluminum hydraulic lift platform, safe and reliable braking, set the balancing valve, balancing loop back to the oil on the road, keeping pressure on the rate of decline from the weight change, the throttle valve flow control lift speed. For the safe and reliable braking aluminum lift platform manufacturers, to prevent accidental aluminum lift platform, increase the check valve, namely hydraulic lock, ensure that when unexpected burst hydraulic line can be safely self-locking. Overload installed voice alarm, to distinguish overload or equipment failure. 7. scissor lift: is extensive use of aerial work equipment. Its scissor mechanical structure Dalian aluminum lift platform, the lift station lift have high stability, large platform and a higher carrying capacity, so that a greater range of operations at high altitude, and for many people simultaneously. It enables high-altitude operations more efficient, safer and more secure. 8. The chain lift: Due cylinder drive chain to enhance chain-lift to give the name. Double-masted aluminum lift platform, Dandong aluminum lift platform, aluminum lift blue card from Jinan blue sky Lifting Machinery Limited. Jinan blue sky Lifting Machinery Co., Ltd.
