<p>The locking system for a tool fitted to a carrier frame (2) on a loader arm (B) consists of locks (32,33) controlled by a hydraulic locking cylinder (3). The locking cylinder is fed with fluid through a valve (6) from a pressure chamber (100) such that the locks cannot be released while the pressure is above a set level. The system has two coaxial and opposite locks fixed to the rod and housing of the locking cylinder with springs (20) to release them.</p> |
