A WEDGE AND SPOOL ASSEMBLY

摘要

A wedging device is suitable for insertion in aligned apertures between components of earth moving equipment such as an adaptor and a bucket of an excavating device. The wedging device is expandable to wedge together the adaptor and the bucket. The wedging device has a typically C-shaped insert or spool cooperating with a wedge element, the spool and wedge element being interconnected by a tensioning screw which upon rotation in either direction respectively forces the wedge downwardly so that the wedging device achieves its wedging function, and in the reverse direction the wedge is pulled up to release the engagement so that the parts can be disconnected.
