Grab Bucet with Straight Linear Progressive Movement of Jaws

Special rowing up grab buckets are used in construction for performing clearing, loading and unloading functions; when mining thin layers of soil and basic materials. The efficiency of grab buckets with large opening of the jaws can be sufficiently increased by providing straight linear progressive movement of the jaws when the angle of shearing doesn't change. The constructed control algorithms allow to detour the obstacles, move in straight and curve trajectories with the specified speed, to decrease the rate of construction’s movement, to perform orientation of construction and provide its smooth installation into the projective position.
