GRYVOZE Granite Slab Lifting Clamp 770 lbs
Maximum load: 770 lbs (350 kg). Opening: 4-18 cm (1.6-7.1 inches). Built from thickened alloy stainless steel via high-temperature forging for durability and corrosion resistance. Rubber anti-slip pads and polyurethane contact surfaces help prevent stone damage and reduce noise, vibration, and wear. Best for mid-sized slabs and situations requiring adjustable opening while maintaining a strong grip. Use caution with very irregular shapes or surfaces that could push clamps beyond their opening range.
GRYVOZE 705 lbs Large Slab Lifting Clamp
Capacity: 705 lbs (320 kg). Opening range: 0-6.5 cm (0-2.6 inches). Features a locking device to hold the grip at maximum opening, enabling automatic clamping after release. Made from thickened alloy steel for safety and longevity, with a forged lifting ring designed for heavy-duty use. Best for precise clamping on small to mid-size slabs; avoid oversized slabs where opening may be insufficient.
GRYVOZE 1763 lbs Granite Slab Lifting Clamp
Large-capacity clamp with adjustable opening from 14″ to 35″ (36-90 cm) and a maximum load of 1763 lbs (800 kg). Constructed from thickened alloy steel, forged at high temperature for safety, durability, and corrosion resistance. Includes a rubber anti-slip pad to prevent stone damage and improve grip. Best for very large slabs or multi-block assemblies; better to use with hydraulic or crane-assisted lifting. Limitation: significantly heavier and bulkier, requiring appropriate rigging and space.
HEYVOZE 2646 lbs Granite Slab Lifting Clamp
Opening range: 16.5″–42.5″ (42-108 cm). Maximum load: 2646 lbs (1200 kg). Heavy-duty alloy steel, hot-forged for robust strength and corrosion resistance. Anti-slip polyurethane rubber pads protect stones, and an adjustable chain offers flexibility in lift height. Choose this for high-volume, industrial-scale projects or when handling very large slabs. Limitation: heavier and more complex setup may require additional safety measures and proper rigging.
YATOINTO Granite Slab Lifting Clamps 770LBS
Capacity: 770 lbs (350 kg). Opening range: 11.81-20.08 inches (30-51 cm). Alloy steel forged at high temperatures for safety and durability. Features include a nut expansion pin for secure placement and a chain for hanging the gripper on machinery. Best for versatile mid-to-large slabs and scenarios requiring adjustable chain length. Limitation: opening range is still narrower than some larger clamps, so very wide slabs may require a separate tool.
Buying Guide
What opening range do you need? Choose clamps with an opening range that matches your typical slab widths. Adjustable clamps offer the most versatility, while fixed-opening designs excel in fast, repetitive lifts.
Material and build quality matter. Look for thickened alloy steel, high-temperature forging, and corrosion resistance to ensure long service life in harsh shop environments.
Grip and surface protection are essential. Rubber anti-slip pads and polyurethane contact surfaces help prevent stone damage and reduce chipping during handling.
Release mechanism and safety features. Clamps with locking devices or automatic clamping after release improve reliability and reduce manual intervention during lifts.
Auxiliary hardware. Some models include chains, spare rubber pads, or lifting rings. Consider whether you need these accessories to complete your setup.
