In mining, quarrying, tunnel excavation, and urban construction, hard rock has always been a major obstacle to project progress. Traditional blasting methods involve complex approval processes, high safety risks, and severe noise and dust pollution, while hydraulic breakers are extremely inefficient against medium-hard and harder rocks, producing only a few cubic meters per day.
The rock splitter for excavator, a new type of excavator attachment, is directly mounted on the excavator and utilizes a hydraulic system to generate hundreds of tons of static splitting force, capable of splitting rock from within within seconds. Non-explosive, vibration-free, low-noise, and directionally controllable, it is becoming the preferred rock-breaking solution for an increasing number of engineering teams.
YG, as a professional construction machinery manufacturer, has sold its full range of hydraulic rock splitting equipment to over 100 countries and regions, including the United States, Sweden, Australia, Malaysia, Mexico, Saudi Arabia, and South Africa, and it is widely used in granite mining, limestone mining, tunnel excavation, municipal foundations, and concrete demolition.
Common Types of Rock Splitting Equipment
- Hydraulic Rock Splitter (Electric/Diesel Power Station)
- Portable and flexible, suitable for small-scale, precision operations.
- Splitting force: 250-800 tons, requires an external power station.
- Suitable for indoor demolition, small mines, and partial tunnel repair.
- Excavator Rock Splitter (Excavator Attachment)
- Directly attached to the excavator, utilizing the excavator’s hydraulic power.
- Splitting force: 500-3000 tons, capable of handling large rocks.

What Are the Core Features of the YG Excavator Rock Splitter?
- Super static load splitting force, easily breaking hard rock. YG excavator rock splitters utilize dual-stage hydraulic synchronous pressurization technology, with a single-gun splitting force of 500-6000 tons (different models), and a splitting time of only 10-15 seconds. Whether it’s granite, basalt, limestone, or concrete, it can quickly split it. The crack width can reach 32-35 mm, far exceeding that of traditional equipment.
- Direct drive from the excavator, no additional power required. Directly mounted on the excavator’s boom, it utilizes the excavator’s own hydraulic system for power, eliminating the need for an additional power station or generator. It can start working on-site immediately, is easy to relocate, and one excavator with one attachment is sufficient for the breaking operation.
- Static, silent operation, environmentally compliant. The working process is vibration-free, impact-free, low-noise, and dust-free. It fully complies with regulations when operating near residential areas, hospitals, schools, or in mining areas with environmental requirements.
- No blasting permit required, saving approval and waiting time. No need to apply for a blasting permit, saving time.
- Precise and controllable direction, high yield. The splitting direction can be precisely controlled, and the crack direction is consistent with the design. When extracting stone in quarries, it maximizes the integrity of the raw blocks, increasing the yield by 15%-25%. Selective mining is possible in mining operations, reducing dilution.
- One-person operation, safe and efficient. The excavator operator remotely controls the machine from the cab, keeping personnel away from the splitting face, significantly improving safety. No special certifications are required for blasting workers, safety officers, or other specialized positions. Compared to blasting, it saves a significant amount of time on drilling, loading explosives, setting up warning and evacuation points, and smoke and hazard removal.
- Multiple model compatibility, covering mainstream excavator tonnage. YG offers a full range of excavator rock splitters from small to large, compatible with 5-60 ton excavators. A 20-ton excavator can be equipped with a medium-sized rock splitter, making the investment threshold low.

What Is the Working Principle of an Excavator Rock Splitter?
- Step 1: Drilling. First, use a rock drill or excavator to drill a hole of a specified diameter and depth in the rock. The size and depth of the hole are determined by the rock splitter model; for example, a YGM-S280 requires a hole with a diameter of 110mm and a depth of at least 1700mm.
- Step 2: Inserting the splitting head. Operate the excavator to align the rock splitter’s splitting head with the drilled hole and insert it. The splitting head consists of a central inner wedge and two outer wedges on either side. Initially, they are closed, allowing for easy insertion.
- Step 3: Hydraulic splitting. Start the hydraulic system; high-pressure oil pushes the cylinder piston downwards, driving the central inner wedge forward. The inner wedge, like a wedge, pushes the outer wedges apart, generating a huge lateral splitting force. This force acts on the inner wall of the borehole, splitting the rock in the predetermined direction within a few seconds. After splitting, the hydraulic cylinder retracts, the wedge returns to its original position, the splitting head is pulled out, and the machine moves to the next hole to continue working. The entire process is a continuous cycle with extremely high efficiency.
Why Can Static Force Split Hard Rock?
Rock has high compressive strength (granite has a compressive strength of 100-250 MPa), but very low tensile strength (only 1/10-1/20 of its compressive strength). The rock splitter utilizes this weakness of the rock—by applying lateral tensile force from the inside, the rock naturally splits from its weakest point. This is why rock splitters are more effective on harder rocks.
