Abstract
The device comprises a gripper (15) whose arms (16, 17) hold at their free end an on-loading mechanism (18, 19) designed to engage a load (13) by gripping accessories (14). Two connecting rods (21, 22) constitute a deformable diamond with the upper part of the gripper (15). The lower ends of connecting rods (21, 22) are hinged to a shoulder (27) of a guide column (28) on which moves a slide (29) forming the head of the gripper (15). Two jacks (45, 46) control the opening and closing of the gripper (15). A connector arm (30) links the shoulder of column (28) to a turning grappling rope (10) and allows the center of gravity to be corrected by a jack (52). This gripping device is intended for use with raising devices such as turret slewing cranes.
