Electric or hybrid working vehicle comprising a lifting arm

A working vehicle, comprising:

• a chassis including two longitudinal members parallel to each other and extending parallel to a longitudinal axis of the working vehicle;
• a lifting arm extending parallel to the longitudinal axis, the lifting arm being articulated on the two longitudinal members and between the two longitudinal members so as to be pivotable with respect to the two longitudinal members about a pivot axis extending perpendicularly to the longitudinal axis;
• a pair of front wheels mounted on a front end portion of the longitudinal members of the chassis and a pair of rear wheels mounted on a rear end portion of the longitudinal members of the chassis;
• wherein each wheel of at least one pair among the pair of front wheels and the pair of rear wheels is rotated by a drive device independent of all the other wheels, is suspended on the chassis by a suspension device independent of all the other wheels, and is orientable with respect to the chassis by an orientation device independent of all the other wheels.
