Integrated Drill & Splitter for Excavator — YG-152 Malaysia Project Case

Southeast Asia has a high concentration of highway and infrastructure projects, with granite formations widely distributed. However, in densely populated areas, traditional blasting and breaker work are increasingly difficult to get approval. Noise, vibration, dust, and safety risks can all halt projects.

Against this backdrop, an excavator attachment integrating drilling and splitting functions is attracting growing attention. integrated drill & splitter for excavator achieves hard rock excavation by static hydraulic force. It requires no blasting, creates minimal vibration, and supports single-person remote control operation.

This article presents a full operation process of the YG-152 excavator mounted integrated rock drill & splitter on granite with 120–160 MPa compressive strength through an actual construction case in Penang, Malaysia.

Malaysia Project Background

This integrated drill & splitter for excavator was deployed for a highway widening project in Penang, Malaysia.

Project Overview:

• Location: Penang State, Malaysia
• Project Type: Highway widening — rock slope excavation and foundation trench construction
• Rock Type: Dense granite, uniaxial compressive strength 120–160 MPa
• Total Rock Volume: approx. 18,000 m³
• Working Conditions: Steep slope (55°–70°), narrow access road, residential areas within 200 meters

Project Challenges:

• Traditional blasting is not feasible due to nearby residential zones and strict environmental regulations
• The hydraulic breaker initially rented by the client only achieved 80 m³ daily output on this granite
• Slope construction required multi-angle drilling, including vertical, horizontal, and inverted drilling
• The scheduled construction period was only 50 days, while rock excavation alone would take more than 200 days using breakers

The client needed equipment with strong rock-breaking capacity and low noise to meet local noise regulations.

Why Choose YG Integrated Drill & Splitter for Excavator

The contractor evaluated three solutions before construction and finally selected the YG-152 integrated drill & splitter for excavator:

Solution 1: Hydraulic Breaker

• Low efficiency on hard granite (only 80 m³ per day)
• Heavy vibration that endangers surrounding building structures
• Noise exceeding limits set by Malaysia’s Department of Environment

Solution 2: Expansive Agent (Non-blasting Demolition Agent)

• Each cracking cycle takes 8–12 hours
• Cannot meet the 45-day construction schedule
• Performance drops significantly in humid conditions

Solution 3: YG-152 Integrated Drill & Splitter

• One cycle completes both drilling and splitting; rock cracks within seconds
• Static operation: no vibration and low noise
• Wireless remote control for single-person operation
• Multi-angle working capacity to fit slope requirements

Key Selection Factors:

• Swedish rock drilling technology plus patented drill frame for precise positioning and long service life
• Italian hydraulic booster system. Two-stage cylinders deliver double boosting force to provide stable splitting power
• Equipment weight is concentrated at the rear of the excavator bucket arm and dipper arm, ensuring balance during steep slope work
• Smaller models can match 20-ton excavators, and the client’s existing 42-ton excavator can work directly

Key Features of Excavator Mounted Integrated Rock Drill & Splitter in Malaysia Project

The field performance of excavator mounted integrated rock drill & splitter is as follows:

Static & Safe Operation:

• Operates under controlled hydraulic conditions with no blasting risks
• No complex safety warning zones required
• Work within 200 meters of residential buildings with zero complaints

Environmental Performance:

• No vibration during rock splitting
• Noise far below the 75 dB(A) boundary limit set by Malaysia’s Department of Environment
• Onboard screw air compressor system enables efficient dust removal
• Strong suction paired with high-efficiency filtration achieves nearly dust-free construction

Efficiency on Hard Granite:

• Two-stage splitting cylinder with maximum 160 KN thrust force
• Crack width can reach 55mm, enough to split rock from the base
• Daily output: 320–380 m³ (around 4 times that of hydraulic breakers)
• Total 18,000 m³ of rock work finished in 48 days, within the adjusted schedule

Multi-angle Drilling Capacity:

• Vertical drilling for foundation trenches
• 55°–70° inclined drilling for slope cutting
• Inverted drilling when the dipper arm extends over the slope edge
• The drill frame maintains accurate positioning at all angles

Wireless Remote Control Operation:

• One operator completes all drilling and splitting work via wireless remote control
• Operators stay away from rock faces for higher safety
• No extra manpower required to cut labor costs

Working Scope of Hydraulic Rock Drill and Splitter in Malaysia Construction

hydraulic rock drill and splitter handled multiple types of work in this highway project:

Foundation Trench Excavation:

• Vertical drilling along planned trench lines
• Split granite into movable blocks
• Trench size: 1.5m(W) × 2.0m(D) × 120m(L)

Slope Cutting:

• Drill holes at 55°–70° along hillsides
• Split rock layer by layer to build slopes following design contours
• No overbreak; splitting direction and size can be precisely controlled

Secondary Breaking of Large Rock Blocks:

• Break oversized granite into transportable sizes
• Clean splitting along drill holes without secondary handling

Precise Work Near Structures:

• Vibration-free operation within 15 meters of existing culverts
• Rock removal beside existing roads
• Splitting direction preset to avoid damage to nearby facilities

Versatility Highlights:

• Single machine handles all three types of work without changing attachments
• 4,850mm piling beam reaches deep into rock surfaces
• 2,600mm drilling stroke covers most hole depths in one single stroke
• Onboard dust control system keeps work areas clean

FAQs about Hydraulic Rock Drill and Splitter

Q1: What rock types can the integrated drill & splitter for excavator handle?

YG-152 works on hard rock with compressive strength up to 160 MPa and above, including granite, basalt, and quartzite. The two-stage splitting cylinder delivers a maximum of 160 KN thrust force and is specially designed for ultra-hard rock conditions.

Q2: What size excavator is required? YG-152 matches 36–48 ton excavators.

Smaller models in the YG series fit 20-ton excavators. Equipment weight concentrates on the rear of the bucket arm and dipper arm of excavators, so balance issues will not occur at any working angle.

Q3: How much efficiency gain compared with hydraulic breakers?

On hard granite (120–160 MPa), the daily output of rock drilling and splitting machine is usually 3–4 times that of breakers of the same class. In this Malaysia project, the average daily output reached 350 m³ versus 80 m³ for breakers under identical rock conditions.

Q4: Can it work on steep slopes and in narrow spaces?

Yes. The machine supports multi-angle drilling: vertical, horizontal, inclined, and inverted. Its weight distribution design solves the forward center-of-gravity problem when the excavator dipper arm stretches out. It can also be lifted into confined spaces such as metro shafts for operation.
