Description

Technical Field

[0001] This utility model relates to the field of stone pier handling technology, specifically to a stone pier handling and lifting device. Background Technology

[0002] A stone block is a stone block, specifically a block made of wide and thick stones, used to block some vehicles.

[0003] For the hoisting of stone piers, steel wire ropes or slings are usually used directly for binding on the construction site. This hoisting method has low technical requirements, is not limited by the tools used, and the binding method can be determined according to the specific size and weight of the stone pier. However, it has the following drawbacks: binding wastes manpower and time, resulting in high labor and time costs; the standardization and safety of binding are low, which can easily lead to the safety risk of spherical components falling off during hoisting due to insecure binding. Therefore, we propose a stone pier handling and grabbing hoisting tool. Utility Model Content
