What is an Excavator Rock Drill and Splitter?

An excavator rock drill and splitter is an integrated drill-and-split attachment mounted on an excavator. Using the excavator as the mobile platform and hydraulic power source, it is equipped with a rock-drilling unit, hydraulic splitting unit, piling beam, hydraulic control system, and auxiliary dust-removal system on the front end.

Its basic working procedure is as follows:

1. The excavator moves the integrated rock drill and splitter to the target rock surface, and adjusts the working angle to vertical, inclined, horizontal, or inverted according to construction requirements.
2. The rock-drilling system drills holes to the preset diameter and depth in the rock.
3. The splitting unit enters the drilled hole, and high-pressure splitting force is applied via the hydraulic system.
4. Cracks are generated inside the rock, and controlled fracture is achieved along the designed direction.
5. The excavator moves to the next working point for continuous drill-and-split construction.

This method does not rely on explosive impact. Instead, it breaks rock by internal static splitting force after drilling. Therefore, it is especially suitable for areas near residential districts, subway projects, around precision equipment, confined foundation pits, mine slopes, and sites where blasting is prohibited. Industry data shows that drill-and-split equipment applies controlled hydraulic pressure inside drilled holes to create controllable cracks in hard rock or concrete. Its working principle is different from hydraulic breakers that rely on continuous impact.

Why Choose Excavator Rock Drill and Splitter?

Compared with hydraulic breakers

Hydraulic breakers break rock by high-frequency impact, suitable for general rock, concrete demolition, and partial crushing work. However, for ultra-hard rock, thick rock strata, or scenarios requiring controlled crack direction, breakers may suffer reduced efficiency, high noise, obvious vibration, and rapid wear of chisels.

Advantages of integrated rock drill and splitter:

1. Drill first and split from inside, ideal for high-hardness rock.
2. Relatively lower impact and vibration during operation.
3. Rock cracking can be controlled via hole positions and splitting direction.
4. No frequent switching between drilling rig, splitter, and excavator.
5. Under suitable hard-rock working conditions, the working efficiency of the YG drill-and-split machine can reach about 4 times that of traditional breakers.

It should be noted that efficiency improvement is based on actual rock properties and construction plans. For rocks with well-developed fractures, moderate strength or small volume, breakers may still be a cost-effective choice. For projects with ultra-hard rock, blasting-forbidden zones, low-vibration requirements, or precise crack-direction control, the drill-and-split machine delivers more prominent advantages.

Compared with a separate drilling rig plus splitter

When using a combination of independent drilling rig and splitter, drilling must be finished first before the splitter is moved or lifted into the hole. This setup requires more equipment and places higher demands on site space, manpower, and construction organization. Especially in tunnels, foundation pit bottoms, and narrow working faces, equipment relocation and repeated positioning consume plenty of time.

Advantages of Integrated drill & splitter for excavator:

1. Drilling and splitting are integrated in one attachment to reduce equipment quantity.
2. The excavator provides mobility, positioning, and hydraulic power for better maneuverability.
3. Saves waiting time for splitter setup after drilling.
4. Main procedures can be completed by one operator via remote control and excavator operation.
5. Improves construction continuity in narrow spaces, multi-angle, and complex cross-section sites.

Compared with blasting construction

Blasting is suitable for large-scale rock excavation, yet brings issues including approval procedures, safety alerts, vibration, flying rocks, noise, dust, and protection of surrounding structures. In urban construction, plant renovation, subway projects, areas near residential buildings and sensitive facilities, blasting is often impractical or subject to strict restrictions.

Advantages of excavator mounted drilling and splitting machine:

1. No explosives or detonation work, reducing blasting formalities and alert management.
2. Enables fine, hole-by-hole and section-by-section directional rock fracture.
3. Perfect for construction sites close to buildings, roads, underground pipelines, and precision equipment.
4. Flexible movement and positioning within limited working surfaces.
5. Helps reduce impacts on nearby personnel and the environment.

How to Select a Suitable Integrated Rock Drill and Splitter?

When selecting an excavator rock drill and splitter, comprehensive evaluation should cover four aspects: rock conditions, excavator specifications, construction objectives, and site constraints, instead of only focusing on equipment weight or drilling depth.

Key points to confirm:

1. Rock type, compressive strength, integrity, joints and fissures, weathering degree.
2. Rock thickness, excavation volume, and target construction cycle.
3. Existence of free faces and whether free faces need to be created by hole layout.
4. Excavator tonnage, hydraulic flow, system pressure, stability, and attachment mounting conditions.
5. Requirements for vertical, inclined, horizontal, inverted, or high-reach arm operation.
6. Site restrictions on blasting, vibration, noise and dust.
7. Whether the project is in tunnels, deep foundation pits, underground works, slopes, or densely populated areas.
8. Need for a screw air compressor, slag-blowing device and high-efficiency dust-removal system.
9. Requirement for wireless remote control to improve operational safety near high-risk rock faces.
10. Project requirement for continuous operation, as well as demands for spare parts, maintenance, and after-sales service response.

For example, for projects with 36-48-ton excavators, thick hard rock, and deep-hole drill-and-split demands, YG-152 is a key model for evaluation. For sites with limited space, lower-tonnage excavators, or mainly partial hard-rock treatment, lightweight excavator rock drill and splitter adaptable to 20-ton-class and above excavators can be considered.
