Claim:
A remote control for a heavy construction machine comprising: a body which comprises at least one cavity running between an open end opening onto at least a top face of the body and a bottom at the opposite end to the open end, at least one first pushrod which runs between a head end and a foot end, which is mounted to slide back and forth in said at least one cavity of the body in an axial direction between a rest position and a depressed position, and which is intended to control at least a first receiver external to the remote control, and a handle which comprises a transverse skirt and which is mounted to pivot with respect to the body opposite the top face of said body to control the back and forth movement of said first pushrod, the skirt simply resting against the head end of said pushrod, and the axis (Y-Y) of the handle making a variable acute angle with the axis (X-X) of the pushrod, wherein the handle extends parallel to the axis of the pushrod when the pushrod is in the rest position, wherein at least the head end of the first pushrod can also move toward a protruding position which is on the opposite side of said rest position to the depressed position, first elastic return means urge the head end of the pushrod toward its protruding position so that at least the head end of the first pushrod has an autonomous upward movement, the head ( 12 , 67 ) of the first push rod ( 3 , 62 ) has an autonomous rising movement to follow the skirt ( 10 ) when the handle ( 4 ) is swiveled, and the remote control further comprises detection means for detecting every position occupied by the head end of the first pushrod comprising a rest position, a depressed position, and a protruding position occupied by the head end of the first pushrod between its withdrawn and pushed-down positions.
