A drilling and splitting excavator attachment combines rock drilling and hydraulic splitting on one excavator-mounted system. It is designed for contractors who already use an excavator and need a flexible solution for hard rock excavation, foundation work, tunneling, trenching, or controlled concrete breaking.

The attachment drills the required boreholes and then uses a hydraulic splitter to create controlled fractures, reducing the need to move separate drilling and splitting equipment between operations.

Excavator Compatibility and Installation

The drilling and splitting excavator attachment is available for 20–65 ton excavators, depending on the selected model. Proper matching is important for stable operation, drilling performance, and safe attachment use.

Before installation, YG will check the following excavator specifications:

  • Operating weight – to match the attachment weight and working capacity
  • Hydraulic flow – to ensure sufficient flow for the drilling and splitting systems
  • Hydraulic working pressure – to confirm compatibility with the attachment
  • Available hydraulic circuits – for drilling, splitting, and auxiliary functions
  • Boom and arm dimensions – to ensure proper reach and working range
  • Attachment mounting dimensions – to match the excavator connection
  • Working conditions – including access, ground conditions, working angle, and available space

Provide your excavator model, operating weight, hydraulic flow and pressure, and YG can recommend a suitable drilling and splitting attachment configuration.

Flexible Installation and Multi-Angle Operation

The drilling and splitting attachment can be installed on a compatible excavator and can also be lifted into difficult-access working areas when required. Depending on the excavator configuration, the drilling system can work at different angles, including vertical and inverted drilling positions.

This flexibility is useful for tunnels, steep slopes, foundation pits, underground construction, and other locations where access is limited.

Air Compressor Requirements

The rock drilling system uses compressed air during drilling, so the required air compressor should be matched to the selected model.

ModelAir Compressor DisplacementPressure
YG10004.5 m³/min5–8 bar
YG15007.5 m³/min5–8 bar
YG200010 m³/min5–8 bar

The final compressor configuration should be confirmed according to the drilling system, rock conditions, borehole requirements, and project conditions.

Key Benefits of a Drilling and Splitting Excavator Attachment

  1. Drilling and Splitting in One Attachment: The same excavator can perform both drilling and hydraulic splitting, reducing equipment changes between operations.
  2. Flexible Excavator Integration: The attachment can be matched according to excavator size, hydraulic flow, pressure, and mounting requirements.
  3. Multi-Angle Operation: The drilling system supports different working angles, making it suitable for slopes, foundation pits, tunnels, and restricted-access areas.
  4. Controlled Rock Breaking: Hydraulic splitting creates fractures from pre-drilled holes, allowing more controlled rock breaking than conventional impact methods.
  5. Remote or Cab Operation: Depending on the configuration, the system can be operated from the excavator cab or by remote control.
  6. Optional Dust Removal: A dust removal system can be added for projects where drilling dust needs to be controlled.

Applications of the Excavator Drilling & Splitting Attachment

This rock drilling and splitting excavator attachment can be used where large rocks, concrete structures, or hard ground need to be fractured in a controlled manner.

Typical applications include:

  • Hard rock excavation
  • Foundation and basement excavation
  • Tunnel and underground construction
  • Rock trenching
  • Steep-slope excavation
  • Urban construction near existing structures
  • Controlled concrete breaking
  • Quarry and stone excavation

The attachment is particularly useful when controlled rock breaking with reduced vibration is more important than high-impact demolition.

FAQ about Drilling and Splitting Excavator Attachments

1. What information do I need to provide to match the attachment with my excavator?

Please provide the excavator model, operating weight, hydraulic flow, hydraulic working pressure, and attachment mounting dimensions. YG can use this information to recommend a compatible configuration.

2. Does the drilling system require a separate air compressor?

Yes. The rock drilling system uses compressed air, and the required compressor capacity depends on the selected attachment model. YG1000, YG1500, and YG2000 require approximately 4.5, 7.5, and 10 m³/min of air displacement, respectively, at 5–8 bar.

3. Can the attachment be installed or removed easily?

The attachment is designed for excavator mounting and can be installed or removed according to the mounting configuration. For projects that require equipment transportation between different working areas, the attachment can also be lifted or transported separately when necessary.

4. Can the attachment work at different drilling angles?

Yes. The drilling system supports multi-angle operation and can be positioned according to the excavator’s boom and arm. This allows drilling in different directions for applications such as slopes, foundation pits, tunnels, and other difficult-access areas.

5. Can the attachment be used in tunnels or confined spaces?

Yes. Its excavator-mounted design allows the equipment to be used in restricted-access areas where conventional drilling equipment may be difficult to position. For underground projects, the equipment can also be transported or lifted into the working area when site conditions allow.

6. Can it be used where there is limited working space?

Yes. The attachment is suitable for projects where equipment access is restricted, including foundation pits, trenches, tunnels, steep slopes, and urban construction sites. The actual suitability depends on the available working space and excavator configuration.

7. Can the attachment be customized for my excavator?

Yes. YG can customize the mounting system and attachment configuration according to the excavator model, hydraulic specifications, working angle, and project requirements. Send us your excavator details and application conditions for a suitable configuration.
