At present, the power of SQ3.2SK2Q Straight Boom Truck Mounted Crane comes entirely from the pressure energy of the hydraulic oil, i.e., through the high-pressure hydraulic oil to promote the reciprocating movement of the cylinder piston, or to drive the hydraulic motor to rotate so that the hydraulic winches and slewing mechanism to rotate.
So, how is the high-pressure hydraulic oil? Each truck-mounted crane matching the vehicle chassis will be equipped with a hydraulic pump, the engine to provide a source of power. The chemical energy of the fuel is transformed into the mechanical energy of the engine crankshaft rotation, and then drive the gearbox gear rotation, and then through the transmission of the power port with the extractor will be transferred to the hydraulic pump, so the hydraulic pump can be a steady stream of hydraulic oil pressurized into high-pressure hydraulic oil, so as to provide power for the crane to achieve the lifting of goods.
