【High-quality steel alloy】The stone lifting tongs are made of high-quality steel alloy after high-temperature forging and protected by a rust-proof coating. It is safe, resistant to breakage, and has a long service life. Adjustable Opening of the Pliers - The lifting tool adopts an adjustable opening width to accommodate stones of different sizes and features a secure spring mechanism to ensure that the pliers do not slip when lifting or lowering the load. Rubber Mandrel: The stone slab clamp is made of polyurethane rubber material that won't damage the stone during lifting. The textured design increases friction and prevents the stone from slipping. Efficient handling tool: The vertical pliers adopt a scissor design. As the clamping force increases, the clamping force also increases, and the jaw opening becomes wider, which contributes to improved productivity. 【Wide Application】The industrial lifting tongs can be used in conjunction with road construction trucks and stone transport slab lifters, such as lifting concrete blocks, granite slabs, wood, steel plates, metal plates, stone slabs and large prefabricated components.
