ANORDNING FOR GRIPANDE OCH LYFTNING AV FYLLDA SECKAR

摘要

A device for gripping and hoisting packed sacks includes a contrivance for mounting the device onto a hoisting machine, load bearing members rigidly coupled to the contrivance for mounting the device onto a hoisting machine. The load bearing members carry vertical plates hinged thereto and turnable from an actuator. The free ends of the load bearing members has slots whose longer faces are in a position of angularity with respect to the end faces of the load bearing members. The device incorporates also two rods arranged parallel to each other, of which the rod is rigidly fixed with its ends to the vertical plates while the other rod is fitted in the slots of the load bearing members. The load bearing member carries a mechanism for restricting the load upon the actuator imparting turning motion to the vertical plates, said mechanism being kinematically associated with the rod fitted in the slots of the slots of the load bearing members.
