ABSTRACT:
A quick coupling device adapted for mounting a tool to a boom of a carrier includes a coupling structure defining at least one notch and a cam assembly. The cam assembly includes a channel having an open end and a seating wall. The cam assembly is rotatable between an open position and a closed position to facilitate installation, locking and release of the tool from the boom. To lock the tool to the boom, the cam assembly is rotated until the seating wall engages a tool mounting pin received in the channel to effect a firm gripping of the pins.
