Concrete pump truck function analysis

Concrete pump truck, also known by the pressure along the pipeline will be concrete continuous conveyor machinery. By the pump and delivery tube. Form of the structure is divided into piston, squeeze, pressure diaphragm. Pump mounted on the vehicle chassis, and then equip scalable or tortuous boom, on the composition of truck.
Concrete pump is adapted from the truck chassis, which is mounted on the chassis movement and power transmission devices, pumping and mixing device, feeding device and some other auxiliary devices.
Concrete pump power through a power transfer case transfers power from the engine to the hydraulic pump groups or rear axle, hydraulic push the piston driven concrete pump. Then use the boom and pump delivery pipe on the concrete delivery to a certain height and distance.
Concrete pump truck with the engine in addition to drive, but also to drive the pumping mechanism, mixing mechanism and fabrics institutions working device.
Concrete pump power of the working device from car engines.
When concrete pump working, car engine power transmitted through the transmission transfer case, and then after the transfer case switch passed to the hydraulic pumps or chassis bridge.
When the driver is switched to pumping position to issue instructions, pneumatic solenoid valve control box on the transfer cylinder push fork, fork and then push switch to pumping gear isolated position, and cut off power after the bridge to make cars in parking status. Conversely, switch to the driving position.
