Enterprises in the purchase of the lifting platform, the first since the weight and other factors into consideration for the enterprise scope, frequency of work, utilization, rated, select the appropriate requirements of the unit working-level lift. According to the proposed technical parameters, Weihai mobile lifts, conduct market research. Suppliers of choice, the first condition is the need to look at the manufacturer's reputation, then there are service capabilities. As long as product quality, excellent performance, mobile lift platform, safety devices, complete the lifting platform, at a reasonable price, the mobile lift offer, it can be used as the selected object. -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, 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 regulates the flow, control the lifting speed. For the safe and reliable braking, to prevent accidents, increase check valve, namely hydraulic lock, ensure that when unexpected burst hydraulic line can be safely self-locking.
