Abstract

The bearing shaft has two ends (11, 12) which pass through the pairs of lever arms (18) which support the bucket (1). The shaft ends are each connected to an inner boss (16, 17) which locate the arms at the end of the shaft. A side flange on each boss is lined up with an auxiliary shaft (19) parallel to the main shaft. The bosses slide inwards on the auxiliary shaft so that the main shaft ends can be retracted to release the bucket. The mechanism is operated by a hydraulic jack (25) operated from a selector valve.
