Earthquake Hydraulic Grabs

Product Overview: Earthquake Hydraulic Rock Grabs

Maximum Grip. Minimum Maintenance.

When you are on the job site, downtime is the enemy. The Earthquake Hydraulic Grab is engineered for contractors who demand reliability without the headache. Built from high-grade, wear-resistant steel, these grabs are designed to handle the toughest demolition, rock placement, and clearing tasks Australia has to offer.

Unlike standard market competitors that overcomplicate the design, Earthquake prioritises structural integrity and smart engineering. The result is a grab that bites harder, lasts longer, and keeps your repair bills low.

The Game Changer: Why Single Ram beats Twin Ram

The most critical feature of the Earthquake Hydraulic Grab is its Single Ram Geometry. While twin-ram setups are common, they introduce vulnerabilities that can cost you thousands in repairs and lost hours.

Here is why the Single Ram advantage makes Earthquake the superior choice:

1. Superior Protection & Durability

In a Twin Ram design, the hydraulic cylinders are mounted on the outside of the grab. This leaves the chrome rods exposed to damage from rebar, jagged rocks, and debris. One scratch on a rod can mean a blown seal and an immediate stop to work.

The Earthquake Single Ram is mounted housed deep within the body of the grab. It is fully shielded by the heavy-duty steel structure, keeping it completely safe from impact damage during operation.

2. Guaranteed Synchronised Movement

Twin ram grabs rely on hydraulic flow to move both jaws. If one cylinder has slightly less resistance or a worn seal, the jaws can become "lazy" or out of sync, requiring constant adjustment or flow dividers.

The Earthquake Single Ram eliminates this variable entirely. By using a centralised, heavy-duty cylinder, the hydraulic force is applied evenly through the central pivot geometry. This ensures both jaws engage the load with equal pressure and perfect timing, giving you a solid, secure hold without the need for complicated synchronisation valves.

3. Halved Maintenance Costs

It is simple math: Two rams mean double the problems.

• Twin Ram: Two seal kits, more hydraulic hoses, multiple connection points.

• Single Ram: One seal kit, two hoses.

With the Earthquake Single Ram design, you cut your potential leak points in half. When it does come time for a service, you are buying half the parts and spending half the time on the bench.

Additional Key Features

• Bisalloy/Hardox Construction: The body and jaws are constructed from high-tensile, abrasion-resistant steel to withstand grinding and crushing forces.

• Oversized Greaseable Pins: All pivot points feature heavy-duty, greaseable pins and bushes to reduce wear and ensure smooth operation.

• Wide Opening Jaws: Designed with optimal geometry to allow for a massive opening width, maximizing the volume of material you can move in a single pass.

• Five-Finger Design: The interlaced finger design ensures a tight grip on uneven loads like scrap metal, timber, and boulders, preventing slippage.

Summary

If you want a grab that looks fancy, buy a twin ram. If you want a grab that works hard and stays out of the repair shop, choose the Earthquake Single Ram Hydraulic Grab. It is the smart investment for serious operators.
