When carrying out security operations worker, walking back and forth will cause shaking platform. Country this requirement is if the device's high-altitude operations yaw rate is less than 5 degrees, then belong to the normal range of shaking. Jinan Dragon Machinery Manufacturing Co. production of aluminum alloy lift in full accordance with national standards of production, ease of purchase using ...... 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 steady, aluminum hydraulic lift, safe and reliable braking, the exhibition with aluminum lift, balancing valve in the oil return path is set, the balance circuit, keeping pressure on the rate of decline from the weight change, Bristol aluminum lift, regulate the flow by the throttle, self-propelled aluminum lift, lifting speed control. 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. Overload installed voice alarm, to distinguish overload or equipment failure. Xiantao aluminum lift, blue sky brand aluminum lift, hydraulic aluminum lift provided by the Jinan blue sky Lifting Machinery Co., Xiantao aluminum lift, blue sky brand aluminum lift, hydraulic aluminum lift Jinan blue sky Lifting Machinery Co. (www.ltsjpt.com) (www.xcsjj.com) this year introduced a new upgrade, the above picture is for reference only, please call Tel or pictures on this page, for the latest information, contact: Mr. Wang.
