Aardwolf Lifter AL30

Overview

The Aardwolf AL30 Manual Stone Slab Lifter is designed for lifting and transporting thin granite, marble, and natural stone slabs with thicknesses ranging from 0–30 mm. Its manually operated locking mechanism allows the operator to control when the clamp engages and releases, making it suitable for applications that require precise handling and deliberate load positioning.

The AL30 uses Aardwolf’s rigid sliding-jaw mechanism, with the movable jaw travelling along guide rods rather than pivoting on hinged links. An integrated positioning roller helps guide the lifter along the slab edge, while rubber-lined gripping surfaces improve friction and help protect finished stone surfaces during normal lifting operations.

With a Working Load Limit of 1200 kg, this manual stone lifting clamp is suitable for stone fabrication workshops, slab warehouses, distribution facilities, container-loading areas, and installation projects requiring controlled handling of thin stone slabs.

Key Features

• Manual locking mechanism: Gives the operator direct control over clamp engagement and release.
• 0–30 mm grip range: Designed for handling thin granite, marble, and natural stone slabs.
• Rigid sliding movable jaw: Travels along guide rods to maintain stable jaw alignment.
• Integrated positioning roller: Helps guide and align the lifter along the slab edge.
• Rubber-lined gripping surfaces: Improve friction while helping protect finished material surfaces.
• Fully mechanical operation: Requires no electricity, batteries, hydraulics, or compressed air.
• 1200 kg W.L.L.: Provides lifting capacity for demanding stone fabrication and handling operations.

Why Choose Aardwolf?

• Rigid sliding-jaw engineering: The movable jaw travels on solid guide rods, limiting the downward rotation associated with hinged swing-jaw mechanisms.
• Consistent surface engagement: The jaw is designed to maintain plane-parallel contact with the slab, supporting a larger effective gripping area.
• Improved load distribution: Stable jaw contact helps reduce localized pressure that may contribute to edge damage or material breakage.
• Robust mechanical construction: The simple sliding system avoids relying on long hinges and small fasteners exposed to repeated load cycles.
• Proven stone-handling design: Aardwolf lifting clamps have been developed specifically for the practical demands of professional stone handling.

Business Benefits

• Helps reduce the risk of edge chipping and surface damage when handling thin stone slabs.

• Slab installation projects
• Overhead crane lifting operations
• Handling thin finished stone slabs

Frequently Asked Questions

How does the Aardwolf sliding jaw improve lifting stability?

The movable jaw slides along rigid guide rods rather than rotating on hinged links. This helps maintain jaw alignment and consistent contact with the slab surface while the load is being lifted.

Does the AL30 require electricity or compressed air?

No. The AL30 operates entirely through a mechanical locking system and requires no electricity, batteries, hydraulics, or compressed air.

How should the slab be positioned before lifting?

The slab must be fully inserted between the jaws, with the lifter positioned centrally for balanced handling. The gripping surfaces must be clean and dry before lifting.

What is the Working Load Limit of the AL30?

The AL30 has a Working Load Limit (W.L.L.) of 1200 kg. Do not exceed the rated W.L.L. The load must remain centred and stable throughout the lifting operation.
