Hydraulic cylinder piston downward movement (both heavy fall). Explosion-proof hydraulic oil through solenoid valve into the upper end of the hydraulic cylinder, hydraulic cylinder through the lower back to the oil balance valve, check valve, throttle, explosion-proof solenoid valve to the tank. In order to decrease the weight stable, safe and reliable braking, car set balancing valve hydraulic lifting platform supply balance loop back to the oil on the road, keep up the pressure, so that the rate of decline from the weight change, the throttle valve regulates the flow control lifting speed. In order to secure the brake hydraulic lifting platform car manufacturers, to prevent accidents, increase check valve, hydraulic lock that hydraulic lifting platform, to ensure that when unexpected burst hydraulic lines can safely self-locking. Installed voice alarm overload, overload or equipment failure to distinguish. Duct clamps, mainly by the fixed arm, telescopic arm with soft grip, arm and clamping cylinder components. Fixed arm length remains unchanged, as a supporting duct side, while the other clamping elements for fixing. Telescopic divided into two, according to the duct diameter, can easily adjust the length of the structure by means of the screw, as another side to support the duct. Flexible soft zone is divided into two sections, long sections connected by a spring to the rocker arm, short segments are connected to the telescopic boom truck-mounted hydraulic lifting platform offer, buckle connection between the two sections, the length is adjustable. When the cylinder extends, the soft end of the spring is fixed with one end fixed and telescopic boom, then retract cylinder clamping duct. When the hydraulic cylinder retracts St. Branch, vehicle-mounted hydraulic lifting platform price, Hebei hydraulic lifting platform consists of Xinxiang City, St. Branch snorkels Machinery Limited. Xinxiang City, St. Branch Hydraulic Lifting Machinery Co., Ltd. (www.skyyjx.com) located Changyuan Wei Zhang Zhuang Town. Scraps and development in the wave of market economy, the current St. Branch has a high profile in the hydraulic loading and unloading equipment, and enjoys a good reputation. St. Branch Hydraulic get the whole network business alliance certification, marking our service and management level has reached a new height. St. Branch Hydraulic staff willing to work with all people of insight and common development, for a better future.
