Abstract

The suspension unit has a hydraulic control, with a body (12) having two shoulders (28, 27) opposite to similar ones (37, 30) on the bucket. The bucket has an internal channel for control fluid, opening into a circumferential groove (39) into which also opens a main feed (41) from the body. An internal pipe (47) in the body or the bucket opens into the first shoulder of the element concerned, and is connected to the main feed. The pressure of the fluid in the main feed is to such a level, that its charge on the first shoulder of the other one of the two elements, causes the second shoulder to support itself on the corresponding shoulder of the other element.
