Aardwolf Stone Grapple ASG – 4,408 lb WLL 3-Point Grab for Boulders and Rock

The Aardwolf Stone Grapple ASG grabs and lifts irregularly shaped boulders, rocks, and debris with three serrated tines and a manufacturer-stated working load limit of 4,408 lb (2,000 kg). The jaw opens from 13 3/4 in. to 47 1/4 in. (350–1,200 mm), and an internally housed actuator sequences grip and release automatically — one operator, no hydraulics.

Not the right tool for: finished or polished stone — the serrated tines are made to bite raw rock and will mark dressed surfaces.

Frequently Asked Questions

Q: How does the automatic cycle work?
A: An internal actuator alternates states each time the grapple is set down: lower onto the rock and lift to grip; set the rock down and lift to release.

Q: Does it need a power source?
A: No. The mechanism is fully mechanical — it hangs from a crane hook, excavator, or loader with no hydraulic or electric connection.

Q: Why three tines instead of two?
A: Three contact points self-center on irregular shapes, giving a stable lift on boulders that a two-jaw clamp would twist around.
