About this product
Aardwolf Slab Lifter with Rollers AL Series — Auto-Lock Stone Clamp
The Aardwolf AL Slab Lifter is an auto-locking clamp that grips slabs on pick-up and releases them on set-down. Two integrated support rollers protect the slab top edge and let the operator center the clamp by hand. The series spans capacities from 882 lb (AL20) up to roughly 3,307 lb (AL75A) with a force-multiplying grip of about 3 to 1 on most models.
Features
- Size: Being of compact construction, the Aardwolf Slab Lifter AL40 allows for close-packed stone slabs to be lifted out of racks and containers. Lower-height slabs alongside taller slabs offer no problem, as with scissor clamps.
- Versatile: Ideal for construction work. Because the clamping mechanism is to the front of the slab, they allow panels to be placed close against walls.
- Safety: Requires only a small movement of the slab to engage and grip it, which is generally well below the over-balance angle, thus eliminating the danger to the operator.
- Secure: The Aardwolf clamps grip marble and granite slabs firmly. The Aardwolf Slab Lifter AL40 has a force-multiplying factor of approximately 2.5 to 1.
