Summary
Hydraulic dumpingmechanism mainly consists of pneumatic control valve, power take-off, gear pumpdrive shaft, gear pump, etc.
Pneumatic controllifting valve, hydraulic cylinder, hydraulic oil tank, hydraulic pipeline,limit valve and other components.The power of the engine is output from thepower take-off on the transmission, and the gear pump is driven by thetransmission shaft, and the hydraulic pressure is driven by the transmissionshaft.The oil is pressed into the hydraulic cylinder through the gear pump,thus pushing the piston of the hydraulic cylinder to lift the carriage. Therole of hydraulic oilThe piston of the lower hydraulic cylinder will continueto rise. When the hydraulic system is restricted to return oil, the piston willno longer continue to rise.
At this time, thecarriage is at the angle of maximum lifting angle.
Dump truck feature
①. Dump truck is alsocalled tipper and engineering truck.It is made up of auto chassis, hydrauliclifting mechanism,take power device and cargo body.
②. In the civilengineering,it is often used to joint excavator, loader, belt conveyor etc. tooperate to form the production line of loading,transport and unloading.It isused for loading and unloading transportation for earthwork,sandstone and loosematerials.
③. As the loading vancan unload automatically by tilting the angle,it can save the unloading timeand labor, shorten the delivery cycle, improve production efficiency and reducethe transportation cost,so that it is common transportation machinery to beused.
