Rapid tool changing mechanism for excavator, bulldozer or mechanical loader includes quick release couplings for hydraulic lines at sides of mounting frame

摘要

The quick change mechanism (1) has two side pieces (12) joined by crossbars. The top crossbar (3) projects outside the side pieces and may be engaged by hooks (15) on frame pieces (14) on the loading tool (2). The lower crossbar (11) supports a hydraulic locking system (4,5) and has a hydraulic plug-in system (13,24). Flexible and rigid hydraulic lines (7,8,16,17,21) are connected to the system.
