The device is made up of:
– A frame 1;
– A jib 4 (realized starting from two symmetrical arms) articulated at E and D on two pairs of arms 2 and 3;
– A bucket 7 articulated at R on the jib 4.
Arms 2 and 3 are articulated at B and C on the frame 1. The tilting of the bucket is ensured by the hydraulic actuating
cylinder 8+9 (8 = piston rod, 9 = body). This jack is articulated at M on the jib and at R on the bucket.
The lifting of the jib is carried out by two hydraulic actuating cylinders 5+6 (5 = body, 6 = rod).
Each jack is articulated at A on the frame and at F on the j
