Patent ID: 8790063

Claim:
An attachment mounting apparatus for movable work vehicles, which is mounted to left and right front ends of a loader mounted to a front surface of a movable work vehicle, and is used for attaching or detaching an external attachment to or from the loader, the attachment mounting apparatus comprising: left and right attachment coupling brackets connected on first surfaces thereof to the left and right front ends of the loader; and an attachment transfer device including left and right attachment coupling units, which are connected to second surfaces of the left and right attachment coupling brackets and attach or detach the external attachment, and are laterally movable in a same direction or in opposite directions, wherein the attachment transfer device comprises: left and right upper mounting parts and left and right lower mounting parts mounted to upper and lower parts of the second surfaces of the left and right attachment coupling brackets; a hydraulic cylinder unit comprising: a pair of hydraulic cylinder extendible rods being laterally movable to left and right along a pair of driving lateral guide rails fixed in the left and right upper mounting parts; and a first hydraulic cylinder and a second hydraulic cylinder moving the hydraulic cylinder extendible rods in lateral directions; a lateral moving unit comprising a pair of lateral moving sliders being laterally movable to left and right along a pair of driven lateral guide rails fixed in the left and right lower mounting parts; left and right attachment coupling units having a structure for attaching and detaching the external attachment, and vertically connecting the pair of hydraulic cylinder extendible rods to the pair of lateral moving sliders in such a way that the pair of hydraulic cylinder extendible rods can be laterally moved by extendible motions of the first and second hydraulic cylinders and thereby can laterally move the lateral moving sliders connected to the hydraulic cylinder extendible rods.
