EarthQuake Hydraulic Rock Grab – Suits 8T to 10T Excavators

EarthQuake Hydraulic Rock Grab – Suits 8T to 10T Excavators

Industrial-strength grabbing power for serious earthmoving.

The EarthQuake Hydraulic Rock Grab (8T - 10T) is designed for the high-performance demands of the 8 to 10-tonne excavator class. When you are moving sandstone blocks, loading heavy logs onto trucks, or stripping out commercial structures, you need an attachment that matches the sheer power of your machine.

Built with an oversized chassis and reinforced geometry, this grab delivers maximum clamping force to handle heavy, awkward loads safely. It is the ultimate tool for contractors who need speed, precision, and durability in tough Australian conditions.

Key Features

• Massive Clamping Force: The high-capacity hydraulic cylinder provides superior grip, ensuring heavy loads like concrete slabs and large boulders don’t slip during transit.

• Reinforced 5-Finger Design: The heavy-duty interlocking jaws (3 over 2) are built to withstand the high breakout forces of 8-10T machines without twisting or warping.

• Fully Enclosed Hydraulics: We know that demolition and forestry are dangerous work. The hydraulic cylinder is completely armoured within the body to prevent costly damage from rebar, timber, or rock impacts.

• Hardox-Equivalent Steel: Constructed from high-tensile, wear-resistant steel to handle constant friction from abrasive materials.

• Heavy-Duty Pivot Points: Oversized pins and easily accessible grease nipples ensure the grab operates smoothly under heavy loads and lasts for years.

Ideal Applications

• Large Retaining Walls: Precision placement of heavy A-grade sandstone blocks and large landscape rocks.

• Structural Demolition: Tearing down walls, sorting heavy steel beams, and loading concrete waste.

• Bulk Material Handling: Efficiently loading trucks with logs, vegetation, or scrap metal.

• Site Rehabilitation: Handling large tree stumps and heavy debris during site clears.
