Small truck is an extensive range of applications of high quality pump, which is mainly used as the tunnel concrete work, it can not only long-term use, but also has high efficiency, low energy advantages. Operating principle: Small truck to the car chassis is powered drive mechanism for driving and pumped by binning for truck driving ﹑ pumping power transmission and switching mechanism carried out structural design work state, and placed on a truck tilt The pumping mechanism and mounted on a rotating turntable and chassis sections foldable boom commenced for pumping ﹑ cloth as the executing agency. When pumping transportation, mainly fixed turret and legs to the base, and then integrated, electro hydraulic control system, the agencies cooperate with each other ﹑ harmonization. Meanwhile, the car chassis engine driven by the main oil pump transfer case thus producing high pressure oil pressure, and then by controlling the electrical ﹑ hydraulic control system, drive two master cylinder alternating movement, the two master cylinder alternately moving conveyor drive cylinder two delivery pistons, and by the coordination of the dispensing valve operation, will continue to concrete from a hopper suction delivery cylinder, after the pressure in the pump through the dispensing valve into the corresponding pipeline interior, the hose and the rod segment portions of the fabric outflow to the outside, thus completing the entire workflow.
