Lifting And Handling Heavy Stone Materials : This clamp is maximum load-bearing capacity can reach 280KG/617.2LB. There is no problem with lifting a 10-inch precast concrete wall, and it can be lifted continuously for many hours and many days. This tool is not only very useful for grasping and moving heavy objects, it demonstrates the harnessing of gravity and everyday use of physics Stone Lifting Ring Jig : This lifting clamp is a great tool for anyone who must move a lot of weight repetitively. The sturdy lifting ring is forged from manganese steel material and steel plate made of alloy steel. Safe durable strong stability without breaking. Can be reduces the risk of accidents and damage to the stone during lifting Anti-Slip Secure Grip Without Damage : The polyurethane rubber material provides a strong grip without causing any harm or marks on the surface of your materials. The texture design can be non-slip and increase safety. It has good heat insulation, sound insulation, shock resistance and wear resistance Adjustable Opening & Adaptable Able to lift both thicker and thinner materials by adjusting the pivot bolts placement in the jaw arms. The heavier the slab you try to lift, the more it clamps down tightly to hold it in place. Vertical scissor grippers increases grip as the applied tension increases and allows wider jaw opening, contributing to high efficiency Wide Range of Applications : Stone lifting clamp can be easily attached and detached from cranes or other lifting equipment, making it suitable for various applications. To lift various building materials such as stone/wood/drywall/concrete/metal strips to elevated platforms/upper floors/roofs. This versatile tool is up to the task, Manufacturer: GYEQXKT
