The invention relates to a device for automatically unlocking drop pockets in load-suspension members and is used in the field of construction engineering when slinging loads on load-suspension members. The object of the invention is to automatically unlock drop pockets as a function of load in load-suspension members by a mechanism. This is achieved by an eccentric piece being mounted between a bearing block, which eccentric piece, apart from transmitting the load, actuates a toggle lever whose bottom end guides a vertically movable gripper. When load is accepted, a tension spring is tensioned and at the same time the dog catch of the gripper is pressed into the web of the drop pocket. If the device is relieved of load, the drop pocket is pulled up by the dog catch of the vertically movable gripper via the preloaded tension spring and toggle lever and the mechanism is unlocked. <IMAGE> |
