Pivoting tool e.g. bucket, mounting device for e.g. bucket loader, has security unit comprising counterweight positioned based on handle to occupy retracted position corresponding to working or resting position of tool fixed at ground level |
摘要 |
<p>The device has a coupler (4) intercalated between an arm and a pivoting tool, and provided with a hydraulic handle (8) to selectively occupy locking and unlocking positions. A mechanical security unit comprises a movable counterweight (9), whose position is governed by earth-gravity regardless of orientation of the coupler and the tool. The counterweight is positioned and conformed with respect to the hydraulic handle to uniquely occupy a retracted position during orientation of the coupler corresponding to a working position or resting position of the tool fixed at the level of ground.</p> |
