Large Hydraulic Rock Splitters for Excavators | Yantai Gaea

Excavator-Mounted Large Hydraulic Rock Splitters (Hydraulic Rock Splitter)

Hero (Why it matters)

Yantai Gaea large hydraulic rock splitters use hydraulic wedge splitting to create controlled internal cracking, helping you remove hard rock and concrete with low noise, minimal vibration, and reduced risk of flyrock—especially when blasting or impact methods are restricted.

Built for real job sites, our excavator-mounted splitting system is designed for:

• Fast, repeatable splitting cycles

• Precise split direction control

• Efficient quarrying & demolition without explosives

• Safe operation for urban / sensitive environments

Product Overview

Our excavator-mounted hydraulic rock splitter is composed of:

• Hydraulic power unit / pump station

• Splitting gun / hydraulic splitter

• High-pressure hydraulic hoses

• Wedges / splitting inserts and working accessories (based on jobsite requirements)

Carrier: mounted on an excavator, powered by the excavator hydraulic system to drive the hydraulic splitter.

Working Principle

Rock and concrete have high compressive strength but are relatively weaker in tension. Hydraulic rock splitters apply controlled force from the inside out through a wedge system inserted into a pre-drilled hole.

The wedge expansion generates internal tensile cracking and forms a split along a controlled path. After splitting, operators remove the broken material and repeat the workflow.

Key Benefits

1) Blast-free and low-risk operation

Compared with explosive blasting, hydraulic splitting is a static, controllable method. It reduces safety exclusion zones and is especially suitable for projects with strict restrictions.

2) Low vibration / low noise / low dust

Hydraulic splitting works without impact hammering, helping minimize vibration, noise disturbance, flying rocks and dust. Great for jobs near buildings, roads, tunnels, bridges, schools and hospitals.

3) High efficiency & continuous working

The system is designed for fast operational cycles and can support continuous splitting productivity with simple maintenance.

4) More precise and controllable splitting

Operators can pre-determine splitting direction, split shape and intended breakout size, improving material yield and reducing unnecessary secondary processing.

5) Convenient installation on excavators

Yantai Gaea large hydraulic rock splitters are designed for practical jobsite deployment:

• easier transport and setup

• convenient operation and servicing

• suitable for confined or hard-to-reach work areas

Work Process (How customers use it)

1. Drill holes according to the site plan and desired breakout size

2. (Optional) Cut/groove between holes for improved split-plane flatness

3. Insert the splitting gun / wedge assembly and align splitting direction toward the free face

4. Apply hydraulic pressure to generate internal cracking and complete splitting

5. Remove split pieces and recreate the free face if required

6. Repeat for the next sequence until the target volume/structure is removed

Applications

Mining & Quarrying

• Secondary break-up of large stone blocks

• Granite, marble, sandstone, limestone and other hard rock splitting

• Mining with hard conditions where blasting is not allowed or not efficient

Construction & Demolition

• Concrete demolition and reinforced concrete splitting

• Foundation, wall, column, pier, bridge components and bridge sub-structures

• Trenching, road widening and controlled excavation

Infrastructure & Special Projects

• Tunnel enlargement, culvert enlargement, underground space demolition

• Hazardous rock removal and obstacle clearance

• Projects requiring controlled splitting with minimal disturbance

Model Range (No fixed parameter—flexible naming)

To fit different jobsite requirements, we classify excavator-mounted large hydraulic rock splitters by splitting force class.

Choose a model based on your required splitting force level and drilling capability:

• YG-LRS Series (Low to Medium Splitting Force Class)
  For medium-scale rock splitting and controlled demolition projects.

• YG-HRS Series (High Splitting Force Class)
  For hard rock and reinforced concrete splitting where stronger output is needed.

• YG-UHS Series (Ultra / Extra-High Splitting Force Class)
  For the most challenging conditions—large block secondary break-up and heavy demolition tasks.

FAQ

1) Can large hydraulic rock splitters be used in sensitive areas?

Yes. Hydraulic wedge splitting is commonly used where blasting or high-impact methods are restricted—helping reduce noise, vibration and flying debris.

2) Do I need explosives?

In most applications, hydraulic splitting is blast-free. The final approach depends on local regulations, rock conditions and engineering plans.

3) What excavator is required?

Our splitting system is excavator-mounted and powered by the carrier hydraulic system. We will guide you on the best configuration based on your excavator model and jobsite requirements.

4) What determines the number of drill holes and workflow cycles?

It depends on target breakout size, rock hardness, splitting force class, and whether you use optional groove/cut steps.
