Traditional hydraulic breakers hit rocks with brute force, causing loud noise and strong vibrations, making them less welcome in cities and near mining areas. Blasting is efficient but has long approval processes and high safety risks. So is there a third option? The excavator rock drill and splitter attachment gives the answer: drill first, then split, letting the rock crack quietly along a planned direction. After YG equipment was put to use in Guatemalan quarries and construction sites, it delivered satisfying results.

Case 1: Efficiency Improvement at a Quarry in Northern Guatemala
Customer background A stone mining company in Petén, northern Guatemala, mainly quarries and processes granite blocks for construction. The rock is hard, and a traditional breaker could only extract about 30 cubic meters per day, which seriously slowed down the project.
Construction challenges The quarry is close to local communities, so blasting is strictly limited. Using a breaker not only had low efficiency, but the strong vibrations and loud noise also caused repeated complaints from nearby residents. The customer urgently needed a solution that could break hard rock efficiently without disturbing people.
YG solution The YG team recommended the YG-130 excavator rock drill and splitter attachment, which fits the customer’s existing 25 ton excavator. This unit uses two stage cylinder synchronous pressurization, giving high splitting force, long splitting stroke, and a crack width of up to 5.5 cm, ensuring the rock breaks completely from the bottom.
Case process The customer contacted the YG sales team through the official website. After three video meetings to discuss equipment parameters and job site adaptability, YG also provided real operation videos from similar quarries for reference. The customer’s two main concerns were whether the unit could work without a free face and whether spare parts would be available quickly. YG explained the working principle in no free face conditions and promised to ship core spare parts within 72 hours. Finally, the customer placed an order for one YG 130 in August 2025.
Results After commissioning, this integrated rock drill and splitter increased daily output from 30 m³ to over 120 m³, making it 4 times more efficient than a conventional breaker. There were no vibrations, noise, or dust at the site, and the community had zero complaints.
Case 2: Hard Rock Excavation in an Urban Building Foundation Pit in Guatemala
Customer background A local construction company in Guatemala City was building a multi storey commercial building with a foundation pit about 8 m deep and an area of about 500 m². However, they hit hard volcanic rock layers below 3 m, which severely stalled excavation.
Construction challenges The pit was adjacent to existing buildings and busy streets, so blasting was strictly forbidden. Using a breaker not only generated huge noise but also risked damaging nearby old structures with vibrations. In addition, the site was narrow, so large equipment could not enter; only small excavators could be used. The customer needed a low noise, vibration free rock breaking unit that could work in tight spaces.
YG solution YG recommended the YG 130 hydraulic rock drill and splitter, which fits the customer’s existing 22 ton excavator. The unit’s weight is concentrated behind the excavator’s bracket, preventing the center of gravity from shifting forward when the boom is raised or extended, allowing flexible operation in narrow spaces. It uses remote control and can be operated by one person. It produces no vibrations and low noise, fully meeting urban environmental requirements. Even without a free face at the pit bottom, the unit can still drill and split normally.
Case process After the customer contacted YG, YG provided detailed specifications and operation videos from urban job sites. The customer’s biggest worry was whether the unit could effectively split rock without a free face. The YG technical team explained the working principle in detail and provided case data from similar conditions. After two weeks of communication and price negotiation, the customer decided to purchase a YG-130.
Results After the equipment arrived, the customer completed drilling and splitting of the hard rock layer in the pit smoothly. The rocks cracked neatly along the planned direction, making removal easier. During construction, there were no noise complaints from nearby residents or shops, and vibration monitoring data stayed far below safety limits. This drilling and splitting machine helped finish the pit excavation about a week ahead of the original schedule, and the customer was satisfied with its performance.
Frequently Asked Questions About Excavator Rock Drill and Splitter Attachment
Q: What is the difference between an excavator rock drill and splitter attachment and a breaker? A: A breaker breaks rock by impact, creating loud noise and strong vibrations, while the excavator rock drill and splitter attachment uses static splitting force to crack the rock – no vibration, low noise, and 4 times the efficiency of a breaker.
Q: Can a small excavator run it? A: Yes. The YG 130 fits 20 36 ton excavators. Its weight distribution is well designed and will not cause stability issues.
Q: Do I need to drill and split separately? A: No. The integrated rock drill and splitter combines drilling and splitting into one unit. Once positioned, it completes both steps, and a single operator can handle everything with wireless remote control.
Q: Can it work without a free face? A: Yes. The YG drilling and splitting machine is capable of working without a free face – one of its key advantages over traditional splitting equipment.
