【High-quality alloy steel】The paver lift is made of thickened manganese steel and processed by high-temperature forging, which has good toughness and impact resistance. 【Anti-slip chuck】The contact surface with the stone is made of rubber with a textured design that provides anti-slip properties, improving safety and allowing lifting operations to be performed without damaging the stone product. 【Thickened Chain】The chain has undergone a hardening treatment, resulting in high strength, good toughness, and high tensile strength. Equipped with a chain adjuster, the chain length can be easily adjusted. 【7 Sizes Available】The opening size is freely adjustable to meet your needs for different sizes of stone. Opening size: 12 cm - 97 cm (4 3/4 inches - 38 1/4 inches), lifting weight: 325 kg - 1125 kg (715 lbs - 2480 lbs). [Wide Applications] Lifting tools used for moving granite, curb stones, slate, marble, bricks, etc. Widely used in courtyards, construction sites, road and bridge projects, etc.
