UPGRATOR Stone Slab Lifting Clamp is a heavy-duty vertical lifting tool engineered for stone slab transport and installation. This clamp delivers a 2204 lbs. rated load capacity, with adjustable 0.39-1.97 in. opening to grip slabs of different thickness. It comes with 7.8 in. throat depth to handle large marble, granite, air brick and roadside stone panels. Built with high-strength alloy steel frame and thick black rubber pads, the clamp creates strong friction to secure stone firmly without scratching or damaging polished slab surfaces. The heavy-duty lifting hook connects quickly to cranes, small hoists and forklift jibs, widely used in stone quarries, processing plants, warehouses and construction sites. Simple manual operation ensures fast setup and safe vertical lifting. The dual steel-rubber structure offers excellent durability for frequent onsite use, perfect for contractors, stone fabricators and construction workers moving large stone slabs.
