Aardwolf Lifter 50 Automatic with Rollers - AL50AR

Aardwolf Lifter 50 Automatic with Rollers - AL50AR

Aardwolf offers a new version of its patented Aardwolf Slab Lifters. The new Aardwolf Slab Lifter Automatic AL50A has an integrated auto-lock, unlock mechanism (patent pending), which allows the clamp to automatically grip slabs on pick-up and release the slabs on set down. In many situations this makes moving and handling of slabs safer and more convenient.

Features

• Size: Being of a compact construction, the Aardwolf Slab Lifter Automatic AL50A allows for close packed stone slabs to be lifted out of racks and containers. Lower height slabs placed along side of taller slabs offer no problem, as is the case 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 the slab, 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 Automatic AL50A has a force-multiplying factor of approximately 2.5 to 1.

What our Experts Think

• Advanced automatic slab handling solution, the Aardwolf AL50AR (Lifter 50 Automatic with Rollers) is engineered for efficient lifting and placement of granite, marble, and engineered stone slabs in fabrication and installation environments.
• Fully automatic lock-and-release system engages when the slab is lifted and automatically releases once fully lowered, reducing manual steps and improving operator safety.
• Integrated side roller technology protects slab edges while allowing smoother positioning and manual centering during handling operations.
• High-performance load capacity up to 1200 kg (≈2646 lbs) with a strong force-multiplying grip system for secure slab control in demanding conditions.
• Grip range of 10–50 mm (0.4”–2”) makes it suitable for standard slab thicknesses used in countertop, wall panel, and architectural stone applications.
• Compact, low-profile design allows easy access to tightly packed slab racks and improves usability in confined fabrication spaces.
• Rubber-coated jaws and protective contact surfaces help minimize chipping, scratching, and surface damage during lifting and transport.

Q&A

Q: What is the Aardwolf Lifter 50 Automatic with Rollers (AL50AR) used for?
A: The AL50AR is an automatic slab lifting clamp designed for safely handling granite, marble, quartz, and engineered stone slabs in fabrication shops, storage racks, and construction sites.

Q: How does the AL50AR automatic system work?
A: It features an integrated auto-lock and release mechanism that automatically grips the slab during lifting and releases it when the load is set down, enabling efficient one-person operation.

Q: What is the purpose of the rollers on the AL50AR?
A: The built-in edge rollers help protect slab edges from damage and assist in precise positioning and centering during lifting.

Q: What is the grip range of the AL50AR?
A: It is designed for slab thicknesses from approximately 10–50 mm (0.4"–2").

Q: What is the load capacity of the AL50AR?
A: The working load limit is around 1200 kg (2646 lbs), depending on configuration and usage conditions.

Q: What are the key safety benefits?
A: It engages with minimal slab movement (below the overbalance angle), reducing operator risk and improving safety during lifting and transport.

Q: What industries commonly use the AL50AR?
A: It is widely used in stone fabrication, countertop manufacturing, warehousing, and construction for efficient slab handling.

Maintenance Tips

• Inspect automatic locking mechanism before each use for proper engagement, wear, or misalignment.
• Check rollers for free rotation, cracks, flat spots, or debris buildup and clean regularly for smooth slab handling.
• Keep lifting arms, pivot points, and linkage systems clean and free from dust, slurry, and stone residue.
• Lubricate all moving joints and mechanical linkages periodically with light machine oil (avoid rollers).
• Verify hydraulic or automatic actuation system (if fitted) for leaks, stiffness, or pressure loss.
• Ensure all pins, bolts, and safety locks are tightly secured before lifting operations.
• Never exceed the rated 50 mm slab thickness capacity (approx.) and WLL limits.
• Inspect rubber or protective contact pads and replace when worn to prevent slab damage.
• Store in a dry, covered area to prevent corrosion and maintain mechanical reliability.
• Remove from service immediately if locking system failure, roller seizure, or structural damage is detected.
