A device for bachage / uncovering lateral of a box of the loading of the grab type, and the loading box provided with this device for bachage / uncovering

摘要

The casing (1) is equipped with a device of the sheeting / tarpaulin (2), which comprises a tank (20) attached to one (14) of the two lateral walls, and a bar of the winding / unwinding (21) which is attached to the tarpaulin. The bar of the winding / unwinding (21) can roll on the casing in one direction or the other between the two lateral walls (13, 14) of the box, between a first position in which the tank (20) is wound around the bar of the winding / unwinding (21) of the box, and a second position in which the tank (20) is unwound and covers the upper opening. The bar of the winding / unwinding (21) comprises a drive member (22) to each of its two ends (21a, 21b) are not covered by the tank (20). The device of the sheeting / tarpaulin (2) comprises two rails of the driving (23, 24) which extend between the two lateral walls (13, 14) of the box, and which are adapted to be in contact with friction or mesh respectively with the two drive members (22) of the bar of the winding / unwinding, so as to allow the course of displacement in one direction or the other of the bar of the winding / unwinding (21) between the first position and the second position, the transformation of the rotation of the bar of the winding / unwinding (21) in a movement of rotation and translation movement of each of the two ends (21a, 21b) of the bar of the winding / unwinding.
