Abstract (en)
The machine on wheels has a chassis (1) carrying a mast (2). The mast can be raised and lowered by means of a base (4) constituted from two parallel clevises by which the base is fixed to the chassis, the base top carrying the mast pivoting spindle (3). An L-shaped connecting rod (5) has its concavity turned towards the mast and articulated (56) to a first actuator (6). A second actuator (7) connects the base to the connecting rod. The end (51) of one connecting rod branch (52) is connected to the mast pivoting spindle and the other end is connected to the second actuator.
