The utility model provides an improved hydraulic lifting device, including hydraulic lifting car body, ground distribution box, plug and socket, be provided with
oil pump motor, hydraulic
oil pump and
control system on the hydraulic lifting car, and
control system includes from
station PLC, actuating mechanism and feedback mechanism, has set up the socket on the both sides of hydraulic lifting car body, when hydraulic lifting car body removes to the
driveway, the plug can be connected with the socket, realizes the power supply and communication to hydraulic lifting car body, and adopts the
oil pump motor of
electric drive to replace traditional
diesel engine to drive the hydraulic oil pump, can reduce the maintenance frequency, reduces the use cost, reduces the emission of
pollution gas simultaneously, avoids the
pollution of atmospheric environment, when carrying out the container lifting, realizes the
automation of lifting through actuating mechanism, and detects whether the lifting is in place through feedback mechanism, guarantees the stable loading and unloading of container.
