Tianjin Nankai Tianjin Nankai lift lift truck rental rental rental Tianjin Nankai Tianjin Nankai Aerial ladder truck rental leasing [Beijing] works a lift trucks, aerial vehicles take to take power plant by power plant pumps, power take off, flexible shaft cable composition . Power output for the car to pumps, hydraulic energy become. It is a safe and a half by car cab handle the action, by making PTO shafts pull within PTO output gear and automotive transmission gear engaged or disengaged, allowing the pump to work or stopped Note: cars, PTO The PTO is teeth should disengage the pump does not work. 2. Aerial slewing mechanism rotary mechanism by a hydraulic motor, planetary gear reducer, slewing bearings and other components, and its working principle is: pinion hydraulic motor reducer, reducer output shaft rotary push slewing ring, turntable rotation . 3. Aerial central rotary joint central rotary joint, installed in the center of the turntable rotation, working to solve the sub-frame stationary relative to the ground, the upper swing, achieving up oil and electricity by passing off the car, because of the slip ring role, hydraulic lines and wires are not kinked. 4, truck hydraulic system hydraulic system consists of a main pump oil supply system working pressure 14Mpa, flow 25L / min, the working pressure set by the relief valve. How it works: When the PTO gear engaged, drive the main pump operation, the oil tank through the pump output to reach for the valve leg after leg operation is completed, will allocate appropriated handle on the car, then the hydraulic oil on the legs Switching to the oil in the car, on the train part of the work can be carried out.
