ABSTRACT:
An improved implement attaching device for construction equipment is disclosed. The device has an implement mount link hinged to the arm of the construction equipment. A first bracket is provided on the rear wall of the implement and supports the link. A pair of key holes are provided on opposite sides of the first bracket. A pair of keys are provided on the link such that the keys are horizontally movable relative to the link to be inserted into or taken out of the key holes and thereby detachably attaching the implement to the implement mount link. The device also has a lever and a linkage for linearly moving the keys horizontally. The linkage achieves a pantographic motion in accordance with a turning motion of the lever and detachably attaches the implement to the link.
