Abstract

1441233 Excavator buckets POCLAIN SA 15 Feb 1974 [21 March 1973] 7123/74 Heading E1F An excavator bucket has a forward body 1c and a pivotally-connected back the back comprising a main back portion 4c having a planar internal surface 6c, and a connecting element 8c which in the loading position (Fig. 1 not shown) joins the internal surfaces 7c and 6c of the forward body and main back portion, respectively, and in the unloading position (Fig. 3) is retracted relative to the main back portion to a position behind the plane R of the back portion. The connection between the connecting element 8c and the internal surfaces 6c and 7c in the loading position is preferably tangential. Adjustment of the bucket is achieved by means of rams 16c connected between the forward body 1c and the connecting element 8c. the force exerted by the rams being transmitted at appropriate times to the main back portion 4c by engagement of a surface 12c of the connecting element with an abutment 11c on the main back portion. A stop 13c on the main back portion co-acts with a surface 14c on the forward body 1c to define maximum unloading opening of the bucket.
