ATTACHMENT COUPLER FOR HEAVY MACHINERY
An attachment coupler for heavy machinery, which detachably installs an attachment to an arm of the heavy machinery, is provided. A coupler body is coupled to the arm of the heavy machinery. A fixed hook is formed on the coupler body and coupled to the attachment via a first coupling pin which is inserted thereinto. A movable hook is rotatably coupled to the coupler body via a hinge axis and coupled to the attachment via a second coupling pin which is inserted thereinto. A hydraulic cylinder rotates the movable hook to be coupled to or disengaged from the second coupling pin. A locking device includes a locking hook and an engagement device. The locking hook is rotatably coupled to the coupler body via a hinge axis and closes an open end of the fixed hook while being coupled to the first coupling pin. The engagement device rotates in association with the rotation of the movable hook to allow the locking hook to be coupled to or disengaged from the first coupling pin in order that the first coupling pin is prevented from being disengaged from the fixed hook while the movable hook stays being coupled to the second coupling pin. Accordingly, accidental separation of the attachment from the coupler can be prevented.
