Load handling machine and method for controlling a load handling machine

A load handling machine, comprising:

• a wheeled chassis,
• a drive system driving the movement of the wheeled chassis,
• a system for handling a load and borne by the chassis,
• an operating unit,
• a control device for controlling the load-handling system and able to be actuated manually by an operator, the operating unit being configured to receive control signals from said control device,
• an activation member for the manually actuatable control device,
• wherein the handling machine comprises a sensor sensing a parameter indicative of movement of the machine, and in that the operating unit is configured to allow the handling system to be operated using the control device as a function of at least the parameter indicative of movement of the machine,
• wherein, with the operating unit being configured so that, when the activation member is in the actuated state, said unit allows the handling system to be operated as a function at least of the control signals received from the control device, the operating unit is configured to
• start at least one timer defining a time interval in the passage of the activation member from the actuated state to the non-actuated state,
• to prevent the handling system from being operated using the control device when the time interval defined by the timer has elapsed, and
• to reset the timer as a function at least of the data supplied by the sensor of a parameter indicative of movement of the machine during the time interval defined by the timer.
