Main technological innovation points 1)The vehicle hopper tilting is driven by double hydraulic cylinder, which has large driving force and stable operation 2)Hydraulic components are concentrated in the design of the rear part of the device,keep away from heat source,and increase the reliability of equipment operation. 3)Using remote electrical control which can achieve shut down and emergency power off freely. 4)Small equipment volume,save space,convenient operation,flexible application. 5)The hopper is made of cambered pressed-steel plate wholly,increases the strength and reduces the resistance of scrap steel while tipping over (the traditional hopper is made of welded steel plate, but the disadvantage is that too much welding seam reduces the strength and the welding stress causes large deformation, and too much welding seam increases the resistance of scrap steel while tipping over). 6)The cable collecting device running simultaneously with vehicle(avoid damage caused by dragging power line on the ground while vehicle moving) is added at the end of the vehicle. 7)The weight balancing device, improves the efficiency of hopper tipping (helps to make full use of the lever principle, increases tipping force). 8)Greaten the hydraulic station with protective cover specially, enhances the cooling effect, runs easily in high temperature environment for a long time.
