The transportation vehicle (1) has a self loading system based on a movable tailboard (4) which can be raised or lowered between limits shown by (P4) to be in line with the vehicle flat bed or to be in contact with and parallel to the ground. A parallel linkage system, with pin joints (28,6,29,31) is operated by a rope (35) wound on a drum (34). A connecting element (12) is used to adjust the mechanism. The tailboard has a third and vertical position forming a rear wall, achieved by manually pivoting and angling elements (21,23) of supporting strut (20). |
