Lifting machine

A lifting machine (1) comprising:

• a main body (2),
• a manipulator arm (3) that is mounted on said main body (2) and is movable with respect to the main body (2),
• a hydraulic actuator (10, 12, 18) that is configured to move the manipulator arm,
• a hydraulic supply device (6) that is connected to the hydraulic actuator (10);
• and
• a control system comprising:
• a control unit (7) that is configured to receive a movement request signal from a human-machine interface and to command the hydraulic supply device in response to the movement request signal so as to cause the manipulator arm to move on the basis of the movement request signal,
• a position sensor (13, 14, 15) that is configured to transmit a position signal (23) representative of a position of the hydraulic actuator (10, 12, 18) to the control unit (7), the control unit (7) also being configured to detect an end-of-travel stop position of the hydraulic actuator on the basis of the position signal and to command (21) the hydraulic supply device so as to stop the supply of pressure to the hydraulic actuator in response to the detection of the end-of-travel stop position.
