Hydraulic Rock Grabs are specialised handling attachments engineered to securely grip and move large loads with precision across construction, mining, quarrying, forestry, and waste management projects. We supply these high-strength tools to fit machinery weights ranging from 0.5-tonne mini excavators up to 40-tonne civil equipment. Built with a weight-reducing box design that maximises structural strength, the grabbing mechanism utilises rugged teeth and claws powered by heavy-duty hydraulic cylinders backed by an 18-month warranty. Every unit features an integrated component cover panel, a replaceable hardened pivot bush, and specialised wear plates positioned in high-wear areas.

Key Features

Weight-Reducing Box Design

The chassis utilises a specialised box design that significantly reduces the overall attachment weight while increasing its structural rigidity. This structural engineering choice allows the excavator to maintain its lifting capacity without sacrificing the grab's operational strength under heavy side loads.

Shielded Cylinder and Hosing Assembly

The hydraulic system features powerful cylinders protected by a structurally integrated steel cover panel. This heavy-duty shield safeguards the hydraulic cylinders and fluid hosing from falling rocks, demolition debris, and external impacts, while the cylinders themselves are backed by a comprehensive 18-month warranty.

Rod-End Spherical Bearings

The cylinder connections incorporate spherical bearings on the rod ends to facilitate automated stress release during uneven load handling. This design protects the structural welds from twisting forces and prevents premature hydraulic seal failure when shifting off-centre boulders.

Precision Tight-Closure Profile

The geometric alignment of the rugged claws allows the mechanism to close tightly together during operation. This tight-closing capability enables operators to transition seamlessly from lifting large, bulky boulders to sorting small, individual objects with high precision.

Serviceable Pivot Bush and Wear Plates

To ensure long-term field durability, the main hinge is fitted with a replaceable hardened pivot bush that can be easily swapped out during routine maintenance. The primary frame is also reinforced with heavy-duty wear plates welded directly onto the high-wear zones to counter continuous abrasion.

Frequently Asked Questions

These attachments are built for demanding tasks in construction, mining, quarrying, forestry, and waste management. They are primarily utilised for loading haul trucks, placing heavy armour rocks, clearing land debris, and sorting mixed materials.

We manufacture these hydraulic grabbing tools to suit excavator weights starting from 0.5-tonne compact machines up to 40-tonne civil production models. Each attachment is precision-machined to line up exactly with your model's original equipment manufacturer pin layout.

The box design lowers the physical deadweight of the attachment itself while simultaneously increasing its core structural strength. By minimising the attachment's weight, it allows the excavator to allocate more machine breakout force and lifting capacity toward the payload.

Every unit is manufactured with a heavy-duty steel cover panel that fully encloses the hydraulic cylinders and flexible hosing. Furthermore, the rod ends are fitted with spherical bearings to release lateral stress and protect the primary cylinder welds from cracking under twisting forces.

The claws are engineered with a precision geometric profile that allows them to close tightly together. This tight clearance enables the operator to pick up and manipulate smaller individual objects with accuracy, as well as handling large, heavy rock loads.

Operators can configure these hydraulic grabs with optional finger serrations along the claws to enhance mechanical grip on smooth or wet objects. Additionally, the high-friction surface areas can be ordered with specialised hard facing to provide extra structural reinforcement against abrasive wear.
