Abstract
The two jaws of the bucket each consist of two rigid portions, the receptacle and the shovel, which are hinged onto on another around the pivoting axis. They are connected to the chassis and to the control cylinder by the suspension arm and the moving arm. The hinges of each jaw between the receptacle, the shovel, the suspension arms, the moving arms, the cylinder, and the chassis imply four hinged systems, each having four push rods. During a closing movement of the bucket from the position of maximum separation of the jaws, a relative pivoting of limited amplitude occurs in alternating directions between the receptacle and the shovel of each jaw.
