4. In the lead ingot hoisting device provided by the utility model, the connecting piece A and the connecting piece B are both circular iron rings, so that the connection between the connecting piece A and the connecting piece B is more flexible, and the connection between the ring and the ring is more flexible. Buckle, when the hoisting hook is pulled up, the two connectors A will gradually move towards the middle, so that the force of the connector A and the connector B is balanced, and the hoisted lead ingots remain stable.

5. The utility model provides a lead ingot hoisting device, by pulling up the hoisting hook, under the action of the gravity of the two "L"-shaped clamping jaws, the two clamping pads are closely attached to the long sides of the left and right sides of the lead ingot At this time, the hoisting hook is further pulled up to hoist the lead ingot. During the process, under the action of the lead ingot's own gravity, the lower clamping arm locks itself and is not easy to fall off. When unloading, only the hoisting hook needs to be lowered, and the lower clamping arm is It can be released by itself, which is simple and easy to operate, and the work efficiency is greatly improved.
