Real-world case studies from YG Machinery installations across the globe. Each project demonstrates how our equipment performs under actual site conditions — from hard rock excavation in Bulgaria to urban demolition in the United States, from confined-space work in Japan to mining operations in Peru and hillside terracing in Vietnam.
Integrated Drill & Splitter Shipped to Bulgaria
A Bulgarian civil engineering contractor deployed the YG integrated drill and splitting machine on a rock excavation project in the Stara Planina mountain region. The 24kW drill bores 120mm holes at 1m/min to 1600mm depth, then the splitter applies 8,000 tons of splitting force to crack hard granite (80MPa) without blasting. The machine has been operating continuously for over 6 months, eliminating explosive permits and meeting strict environmental requirements.
Drum Cutter Attachment Shipped to United States
A US civil engineering contractor used the YG240 hydraulic drum cutter on an urban road reconstruction and building demolition project. The attachment achieved 180% productivity improvement — pavement removal increased from 15‑20 m²/hour to 45‑55 m²/hour, and reinforced concrete cutting from 8‑12 m²/hour to 25‑30 m²/hour. Vibration levels were reduced by over 80% compared to breakers, noise complaints were eliminated, and dust suppression met environmental requirements.

Concrete Demolition Robot Shipped to Japan
A Tokyo-based contractor deployed the YG concrete demolition robot (4,960kg, 37kW, 21MPa) on a reinforced-concrete building demolition project in the Shinjuku district. The compact tracked machine (1.2m wide, 1.88m high) navigated tight urban spaces with 30° climbing gradient and remote control. Over 4 months of daily operation, it achieved 45‑60 m³/day output, zero hydraulic or engine failures, and 100% uptime.
Breaker Attachment Shipped to Peru
A Peruvian mining contractor operating a copper mine in the Andes Mountains deployed the YG100 breaker attachment on a 12-ton excavator at 3,800 meters altitude. The breaker handles hard andesite rock (150MPa), reducing oversize boulders from 1.2m to under 600mm for crusher feed. Over 5 months of daily operation, it achieved 120‑150 tons/day breaking volume with zero unscheduled downtime.

Mini Excavator Ripper Shipped to Vietnam
A Vietnamese excavation contractor deployed the YG-06 ripper attachment on a 15-ton excavator for hillside terracing. The single-tooth ripper broke through hard clay and weathered limestone that conventional buckets could not penetrate. Over 4 months of operation, it achieved 80‑100 m³/day productivity with 40% time savings on site preparation.
