<p>A coupling device or 'quick coupler' which comprises a housing (250) which can be temporarily attached to a boom (113) using hinge (143) and link (146) pins or can be built into the boom itself and which contains means for connecting (261, 270) the coupling device to a variety of implements (120). The coupler also contains means for adjusting (263, 264, 266) the effective operating distance or range of motion of the connecting means (261, 270) so that the coupler can be used with various implements having different center line distances between the hinge (143) and link (146) pins.</p> |
