Motor-driven grab with articulation points (33-35; 36-38; etc.) for movable grab shells (41-44; 241, 243; 341, 343). The motor-driven grab comprises a convenient number of fastening points (45, 46, etc.) for alternatively fastening one or more actuating devices (26, 28; 226a, 226b; 326a, 326b) in various positions. The actuating devices are arranged for work between the said fastening points (45, 46, etc.) and grab shells (41-44; 241, 243; 341, 343) for actuating the latter. <IMAGE> |
