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.
