Description
Product Overview
The XIIW Granite Slab Lifting Clamp is a purpose‑built tool designed for the safe and efficient handling of heavy stone, concrete, and curb elements. Constructed from high‑grade alloy steel, the clamp offers exceptional strength and resistance to wear, ensuring long‑term durability even in demanding industrial environments. The clamp features a jaw opening that can be adjusted from 10.63 in to a maximum of 19.68 in, allowing it to accommodate a wide range of slab thicknesses and profiles. With a rated capacity of 772 lb (350 kg), it provides the confidence needed to lift and transport large paving stones, curbstones, block steps, and similar non‑tapered elements without risk of slippage or deformation.
Key construction details include thickened, wear‑resistant hooks and a nut expansion pin that locks the steel plate securely in place, enhancing stability during lifting operations. The inclusion of rubber‑filled inserts on the jaws adds a non‑slip surface that protects the stone surface from scratches while delivering a firm grip. The clamp’s vertical steel plate design distributes load evenly, reducing stress concentrations and extending the service life of both the clamp and the material being handled.
Usage
This lifting clamp excels in a variety of real‑world scenarios. It is ideal for construction sites where workers need to move heavy paving slabs, curbstones, and precast concrete elements quickly and safely. Landscape professionals can use the clamp to reposition large stone pavers during garden redesigns, while restoration specialists appreciate the precise control it offers when handling historic stonework. The adjustable jaw opening makes it suitable for both thin tiles and thicker blocks, providing flexibility across multiple project types.
Because the clamp is lightweight yet robust—weighing just under 30 lb—it can be easily carried by a single operator, reducing the need for additional lifting equipment. The rubber‑filled jaws also make it safe for use on delicate surfaces, preventing marring on finished stone or decorative concrete. Whether you are a contractor, a fabricator, or a DIY hobbyist, the clamp’s ergonomic design and straightforward operation enable efficient material handling with minimal training.

FAQ
What is the maximum weight this clamp can safely lift?
The clamp is rated for a maximum load of 772 lb (350 kg), which covers most standard granite, concrete, and stone slabs used in construction and landscaping.
Can the clamp be used on curved or tapered stone pieces?
The design is optimized for parallel, flat, and non‑tapered elements such as curbstones and paving slabs. For curved or tapered pieces, a different specialized clamp is recommended.
How do I adjust the jaw opening to fit different slab thicknesses?
Simply loosen the locking nut, slide the jaws to the desired opening within the 10.63 in to 19.68 in range, and retighten the nut to secure the position. The mechanism is smooth and requires minimal force.
Are replacement rubber inserts available?
Yes, replacement rubber‑filled inserts can be ordered directly from our parts catalog. They are designed for quick installation, allowing you to restore the non‑slip surface without replacing the entire clamp.
