Location: Oman Customer: Building Construction Contractor Equipment: YG1000 Hydraulic Rock Drill and Splitter Carrier Excavator: 20–36 Tons Additional Equipment: Compatible Screw Air Compressor
A building construction contractor in Oman needed a reliable solution for excavating hard rock during foundation construction. The project involved rocky ground in a hillside residential area, where conventional blasting was not an ideal option due to the proximity of nearby houses and existing infrastructure.
The customer already owned an excavator and wanted a powerful hydraulic rock drill and splitter that could work with the existing machine, break hard rock efficiently, and provide better control over excavation operations.
After evaluating the excavator specifications and site requirements, YG recommended the YG1000 hydraulic rock drill and splitter, together with a compatible screw air compressor.
Customer Background: Hard Rock Excavation Near Residential Areas
In parts of Muscat and other developed areas of Oman, residential construction takes place on sloping and rocky terrain. Before building foundations can be constructed, contractors often need to remove hard limestone and other rock formations to reach the required foundation level.
However, excavating rock near existing houses, roads, and other structures presents several challenges.
Blasting Restrictions: Conventional explosive blasting can generate vibration, flying debris, and noise, making it difficult to control when working close to residential buildings.
Hard Rock Conditions: Dense rock formations require powerful equipment capable of drilling and splitting solid rock rather than simply breaking loose surface material.
Limited Working Space: Hillside construction sites often have uneven ground and restricted operating positions, requiring flexible equipment that can adjust to different working angles.
Excavator Compatibility: The contractor wanted to use his existing excavator instead of purchasing an additional carrier machine.
The customer needed a controlled rock excavation solution that could handle demanding ground conditions while making better use of the available construction equipment.

YG’s Solution: YG1000 Hydraulic Rock Drill and Splitter
Based on the customer’s 20–36 ton excavator and foundation excavation requirements, YG recommended the YG1000 hydraulic rock drill and splitter.
The YG1000 combines a hydraulic rock drilling system and a powerful hydraulic splitting mechanism in one excavator-mounted machine. It drills precise boreholes and applies strong lateral splitting pressure to divide hard rock into removable sections.
This makes it suitable for foundation excavation, hillside construction, and other hard rock excavation projects where controlled rock breaking is preferred over conventional blasting.
Why the YG1000 Was Suitable for This Project?
1. Powerful Splitting for Hard Limestone：Equipped with a 22 kW hydraulic rock drill, the YG1000 creates boreholes with a diameter of 115 mm and a maximum depth of 1,600 mm. Its hydraulic splitting system delivers up to 12,000 tons of splitting force, allowing contractors to handle demanding hard rock conditions during foundation excavation.
2. Compatible with the Existing Excavator： The YG1000 is designed for 20–36 ton excavators, matching the customer’s existing carrier machine. This allows the contractor to use his current excavator for rock drilling and splitting without investing in another dedicated carrier machine.
3. Flexible Operation on Uneven Terrain： The machine features a 120° rotation system, allowing operators to adjust the drilling and splitting direction according to the rock surface and excavation position. This is particularly useful for hillside construction, sloping rock surfaces, and foundation areas where straight vertical access is limited.
4. Complete Solution with a Compatible Air Compressor： To ensure the drilling system had a suitable compressed-air supply, YG also selected a compatible screw air compressor for the YG1000.
The recommended compressor displacement is 4.5 m³/min, with a working pressure of 5–8 bar. The complete equipment configuration provides the customer with a coordinated rock drilling and splitting solution.
Customer Benefits: More Controlled Foundation Rock Excavation
For this Oman construction project, the YG1000 provides a practical alternative to conventional blasting for hard rock excavation.
Its integrated drilling and hydraulic splitting design allows contractors to break rock in a more controlled manner, helping reduce dependence on explosives when working near residential buildings and existing infrastructure.
The equipment also offers several practical advantages:
Better Excavation Control: Hydraulic splitting helps divide solid rock into manageable sections, making subsequent excavation and removal easier.
Reduced Dependence on Blasting: A non-explosive rock-breaking method is particularly valuable for construction sites where blasting-related vibration and flying debris are major concerns.
Better Use of Existing Equipment: Compatibility with 20–36 ton excavators helps contractors maximize the value of their current machinery.
Greater Working Flexibility: The 120° rotation function helps operators work on different rock surfaces and excavation angles.
For contractors working on hillside foundations, residential developments, and other construction projects involving hard rock, the YG1000 offers a combination of drilling capability, powerful hydraulic splitting, and flexible operation.
