EarthQuake Hydraulic Rock Grab (Suits 2.8T - 4.0T Mini Excavators)

Maximise the lifting and sorting potential of your 3-4 tonne machine.

The EarthQuake Hydraulic Grab is engineered to withstand the higher breakout forces of 2.8 to 4-tonne excavators. This is the essential attachment for operators undertaking medium-scale retaining wall projects, serious site clean-ups, and vegetation management.

While still lightweight enough to keep your machine balanced, this grab features a reinforced chassis and powerful clamping force, allowing you to handle heavier rocks, larger logs, and bulkier debris with absolute confidence.

Key Features

• Heavy-Duty Interlocking Jaws: The 5-finger (3 over 2) design ensures a secure hold on irregular shapes, preventing slippage when moving large rocks or slippery timber.

• High-Tensile Steel Construction: Built to resist wear and tear in abrasive Australian conditions, ensuring your attachment lasts as long as your machine.

• Protected Hydraulic Cylinder: The cylinder is fully guarded to prevent damage from falling debris or accidental impacts, reducing downtime and repair costs.

• Wide Jaw Opening: Designed with a geometry that maximizes opening width, allowing you to grab larger volumes of material in a single pass.

• Easy Maintenance: Heavy-duty grease nipples are accessible on all pivot points to ensure smooth operation and longevity.

Ideal Applications

• Retaining Walls: Perfect for the precision placement of sandstone blocks and medium-sized boulders.

• Demolition & Sorting: Efficiently strip out structures and sort steel, timber, and concrete for recycling.

• Vegetation Management: Rip out roots and handle larger tree trunks during land clearing.

• General Earthmoving: Move awkward materials that a bucket simply cannot handle.
