ABSTRACT:
A quick coupler assembly for attaching a material handling bucket or the like to the free ends of lift arms extending from a loader. The quick coupler assembly includes an elongated cross member having hitch brackets on its opposite ends. Each hitch bracket includes an end which is received within a socket coupling member on the rear wall of the bucket near the top edge thereof. The opposite end of the hitch bracket is configured for engagement within a lower coupling member on the bucket rear wall. The coupler assembly further includes an attaching lever which is rotatably secured to the backside of the cross member substantially at its mid-portion. The lower end of the attaching lever is movable into engagement within a coupling member on the rear wall of the bucket. The upper end of the attaching lever includes a slidable or rotatable locking bracket assembly which is selectively moved into locking engagement with a locking member on the bucket rear wall. A tilt cylinder preloads the bucket against the quick coupler assembly such that the only force required from the operator is a simple manual movement of the locking bucket assembly into a position for final coupling.
