An extendable frame (4) is hinged near an access sill (5) located above a loading hopper (3) that is carried by the vehicle, and rotationally supports a pair of lifting arms (10) operatively engageable with a bin (11). A support structure (18) rotationally constrained near the access sill (5) operates on the extendable frame (4) to rotate the latter from a stand-by position against a side wall (3a) of the hopper (3) to a gripping position in which the lifting arms (10) are moved away from the side wall (3a). At least one tilting actuator (20) operates between the support structure (18) and the extendable frame (4) to rotate the latter between a rest position in which it develops below said access sill (5) and a tilting position in which it is raised with respect to the access sill (5).
