Abstract (en)
[origin: EP2140991A2] The machine (1) has a traction system including an electric gear motor (2) attached to a base-plate (3) of a chassis. The motor has a speed variator and a storage reel (14) on which an electric cable supplying power to the motor is placed. A reducer (4) of the motor emerges from a transversal traction axle (5) whose ends are terminated by toothed pinions. The pinions transmit movement, through traction chains (8), to toothed crowns (12) of traction wheels (10, 11) located under front sides of the machine, so as to cause displacement of the machine in two directions.
