Aardwolf Lifter - AL20R

Aardwolf Lifter - AL20R

Features

• Size: The Aardwolf Slab Lifter 20’s compact construction allows for lifting close-packed slabs out of racks and containers.
• Safety: Only a small movement of the slab is required to engage and grip the slab, which is generally well below the overbalance angle, thus eliminating the danger to the operator.
• Secure: The Aardwolf clamps grip slabs firmly.  The Aardwolf Lifter 20 has a force multiplying factor of approximately 3 to 1.

What our Experts Think

• Advanced automatic slab lifting system, the Aardwolf AL60AR combines automatic locking technology with integrated rollers for safer, faster handling of granite, marble, quartz, porcelain, and engineered stone slabs.
• Fully automatic lock-and-release mechanism grips the slab securely during lifting and automatically disengages when the load is lowered, reducing manual intervention and improving workplace safety.
• Integrated top rollers help protect slab edges while allowing smooth positioning and precise centering during lifting, loading, and installation operations.
• High working load limit of up to 1,200 kg (2,646 lbs) makes it suitable for demanding fabrication shops, stone processors, and installation contractors handling heavy materials daily.
• Grip range of 15–60 mm (5/8"–2⅜") accommodates many of the most common slab thicknesses used in countertops, wall cladding, flooring, and architectural stone projects.
• Compact front-clamping design allows operators to lift slabs from tightly packed storage racks and position materials closer to walls or workstations, maximizing workflow efficiency.
• Rubber-lined gripping surfaces help minimize chipping, scratching, and surface damage, protecting valuable finished materials during transport and installation.
• Built for professional productivity, reducing handling time while improving load stability and operator confidence throughout the lifting process.

Q&A

Q: What is the Aardwolf Slab Lifter Automatic AL60AR with Rollers used for?
A: The AL60AR is designed for lifting, transporting, and positioning granite, marble, quartz, and engineered stone slabs safely in fabrication shops, warehouses, and construction sites.

Q: How does the AL60AR automatic locking system work?
A: It features a gravity-controlled auto-lock and auto-unlock mechanism that automatically grips slabs when lifted and releases them when set down, reducing manual handling and improving efficiency.

Q: What is the grip range of the AL60AR?
A: The clamp handles slab thicknesses from 15–60 mm (0.6"–2.4"), making it suitable for a wide range of stone slabs.

Q: What is the load capacity of the AL60AR?
A: The AL60AR has a working load limit of 1200 kg (2646 lbs) for heavy-duty slab handling applications.

Q: What is the purpose of the integrated rollers?
A: The rollers protect slab edges from damage and allow easy manual centering of the clamp during engagement and lifting.

Q: What safety features does the AL60AR offer?
A: It requires only minimal slab movement to engage, features rubber-lined jaws to prevent chipping and scratching, and provides a force-multiplying grip of approximately 2.5:1 for secure lifting.

Q: What are the key benefits of the AL60AR?
A: Its compact design allows lifting slabs from tightly packed racks and containers, while the automatic operation and edge-protection rollers improve productivity, safety, and material protection.

Maintenance Tips 

• Inspect the automatic locking mechanism before each use to ensure smooth engagement and secure gripping.
• Check rollers for wear, cracks, flat spots, or debris buildup and ensure they rotate freely.
• Clean rollers, jaws, and frame after use to remove stone dust, slurry, and residue.
• Inspect gripping pads and contact surfaces for wear or damage; replace when necessary.
• Lubricate pivot points, linkages, and moving components regularly with light machine oil (avoid rollers and gripping pads).
• Verify all bolts, pins, and safety locks are tight and fully secured before lifting.
• Never exceed the rated load capacity and use only within the specified 60 mm slab thickness range.
• Inspect lifting eye, frame, and structural components for cracks, deformation, or excessive wear.
• Store in a dry, covered area to prevent corrosion and maintain reliable automatic operation.
• Remove from service immediately if locking failure, roller malfunction, slippage, or structural damage is detected.
