1. The ring body of stone hanging clamp and stone fixture is welded after rolling steel plate. The joint must be firm, and the reinforced plate should be welded when necessary.

　　2, stone lifting clamp, stone fixture rubber sheet can be replaced by brake belt;

　　3, due to the limit of friction Angle, for a size of stone lifting clamp, stone fixture, the diameter of the clamping workpiece is not small, otherwise it can not be self-locking clamping. For different diameter specifications of the workpiece needs a set of different specifications of stone lifting clamp, stone fixture, which is acceptable to large-scale production manufacturers;

　　4. Using the parallelogram four-bar mechanism principle and friction self-locking principle, stone hanging clamp and stone fixture can be deformed into internal fixture, that is, the fixture to tighten the cylinder inside the workpiece, which is used for special hoisting occasions.
