The intelligent synchronous lifting jack hydraulic power unit system is an integrated, self-contained hydraulic unit comprising a power unit, an electrical unit, and control devices. It features high flow rate, simple structure, convenient operation, and high working pressure, with the high-pressure outlet pressure adjustable between 70 and 700 bar. The system operates at 220 V, with a rated current of 20 A and a power rating of 8 kW.

Electrical Control System: The control cabinet serves as the control center, housing a built-in PLC, touchscreen, operation buttons, and servo motor drivers, while also supplying power to the sub-control cabinets and motors. The sub-control cabinets are connected via control signal lines and communication buses to receive and provide feedback on operating status.

Hydraulic Pumps: The system is equipped with six hydraulic pumps. Each is fitted with a 13-liter oil tank; the output lifting pressure equals the retraction pressure, both of which are ≤70 MPa (the maximum operating pressure is locked at the factory; increasing the locked pressure is prohibited). The system is equipped with an oil temperature sensor, an oil level alarm, and a dipstick to monitor oil level and temperature in real time and trigger an alarm promptly when the oil level is too low.

Mobile Cart: Approximately 1,016 mm long, 823 mm wide, and 1,287 mm high (with jacks in the retracted position). A hydraulic pump is mounted at the bottom, a small control cabinet at the top, and jack mounting brackets, risers, and jacks in the middle, enabling the jack cart to quickly transport the jacks to the work site.

Hydraulic Jacks: Six 50Tf hydraulic jacks, each with a high-pressure chamber oil capacity of 5.7 L, a rated pressure of 70 MPa, and a stroke of 600 mm. They are equipped with displacement sensors and feature pressure-loss protection via balancing valves and hydraulic locks.
