Hydraulic control system and forklift

A forklift, wherein a hydraulic control system is implemented on the forklift, the hydraulic control system comprising:

• a hydraulic module, a PLC control module, a hydraulic valve group control module, a manipulation module, and an action module, wherein
• the manipulation module is connected with the PLC control module and is configured to input an operation instruction to the PLC control module, wherein the manipulation module includes a forward/backward switch, a tilt switch, a lateral moving switch, and a lift switch;
• the PLC control module is respectively connected to the hydraulic module and the hydraulic valve group control module, and is configured to
• output a control signal corresponding to the operation instruction to the hydraulic valve group control module, and
• control an activation of the hydraulic module to provide hydraulic pressure to the hydraulic valve group control module;
• and
• the action module is connected with the hydraulic valve group control module, and is configured to perform an action corresponding to the control signal, wherein
• the forklift includes a vehicle body, a fork, and a scissor assembly provided between the vehicle body and the fork;
• the hydraulic module and the PLC control module are provided on the vehicle body;
• a hydraulic valve group control module is provided between the fork and the scissor assembly;
• and
• the action module also includes a forward/backward unit, a tilt unit, a lateral moving unit, and a lift unit;
• and the forward/backward unit, the tilt unit, the lateral moving unit and the lift unit respectively correspond to the forward/backward switch, the tilt switch, the lateral moving switch and the lift switch, wherein a pulley block is provided on an oil line connection between the hydraulic valve group control module and the lift unit, wherein
• the forward/backward unit is configured to receive the control signal from the PLC control module to cause the fork of the forklift to move forward or backward;
• the tilt unit is configured to receive the control signal from the PLC control module to cause the fork of the forklift to tilt forward or backward;
• the lateral moving unit is configured to receive the control signal from the PLC control module to cause the fork of the forklift to open toward both sides or contract toward the middle;
• and
• the lift unit is configured to receive the control signal of the PLC control module to lift or lower of the fork of the forklift.
