A positioning device for a remote control of a heavy duty vehicle or agricultural vehicle includes an elastic element. The elastic element has a fastening portion, configured to be secured to a body of the remote control, and a retaining portion, arranged to cooperate with an actuator of the remote control at a threshold position delimiting a first portion of a displacement trajectory of the actuator, and a second portion of the displacement trajectory, so as to oppose movement of the actuator according to its displacement trajectory along at least one displacement direction upon switching of said threshold position and allow switching at the threshold position in said displacement direction as a result of application of a threshold switching force exerted on the actuator. The threshold switching force is higher than a displacement force necessary for movement of the actuator on the first or second portion of the displacement trajectory.

Positioning device for a remote control of a heavy duty vehicle or an agricultural vehicle

The invention relates to a remote controller for heavy construction machines with a body, comprising a cavity, running between a first outlet end and a base, a first pushrod, running between a head and a base, arranged to slide with a back and forth movement in the cavity along an axial direction, a handle which may pivot with relation to the body, whereby a skirt of said handle is in direct contact with the head. The first pushrod may furthermore be moved to an extended position opposite to the depressed position with relation to the idle position thereof. First elastic return means are arranged in the cavity to force the pushrod into the extended position thereof and detection means are provided to detect the position of the first pushrod.
