Clamp 9, 10 comprises support frame 12, 14 and at least two clamps 13 arranged for simultaneous gripping and releasing of long element 2. Every said clamp 13 has at least two opposed clamping device 15 and self-adjusting mechanisms 19, each being arranged between appropriate clamping device 15 and frame 12, 14. Said stacker comprises stacker tower 4, first and second clamps 9, 10 connected with said tower. Method of stacking consists in clamping of long element 2 by clamp 9, 10 sliding along stacker tower 4 and performing correction motion in direction parallel with axis A of clamp 10 relative to clamp 9 at simultaneous grip of continuous long element 2 by clamps 9, 10. |

Invention relates to hoisting device. Winch has load-bearing frame with two side supports interconnected by lengthwise stiffness elements and mounting elements. Said mounting elements are secured at side supports by fasteners at lengthwise stiffness elements ends. Rope winding/unwinding drum is arranged between lateral support inner sides to run about its axle. Thrust inserts and mounting elements are interconnected by double-shear bolt joint. Lateral supports have paired ledges with appropriate bores. Note here that all said paired ledges in every pair are arranged at some distance from each other while thrust inserts have means of bolt joint to interact with said paired ledges. |
