Transfer trolley hydrostatic driving device and hydraulic control system thereof

The invention discloses a transfer trolley hydrostatic driving device and a hydraulic control system thereof, and relates to the field of transfer trolleys, the transfer trolley hydrostatic driving device comprises a transport trolley rack, support flanges are arranged at the bottoms of two ends of two transfer trolley bottom beam frames in the transport trolley rack, driving wheel brackets are fixed on the support flanges through bolts, driving wheels are rotationally connected to the driving wheel brackets, and the driving wheels are rotationally connected with the hydraulic control system. The hydraulic transfer vehicle has the beneficial effects that the mechanical structure is simplified, the cost is reduced, the operation difficulty is reduced, a low-speed large-torque motor is adopted to directly drive the driving wheels, a complex structure of a gearbox and a bridge combination is omitted, a gear shifting device mechanism is not needed, the cost is reduced, and the operation efficiency is improved.
