Empowering Smarter and Greener Tunnel Construction: XCRUSHER DG Deploys Intelligent Rock Bolting Rigs to Major Rail Project

Intelligent Equipment from XCRUSHER DG Powers Major Rail Tunnel Project

XCRUSHER DG Intelligent Machinery Co., Ltd. has officially dispatched two newly developed DGW551 intelligent single-arm rock bolting rigs to a key national railway infrastructure site. Specially designed for tunnel construction, these cutting-edge machines — dubbed “steel assistants” — will accelerate tunnel reinforcement operations with high efficiency, intelligent control, and environmentally friendly design, supporting the rapid development of China’s high-speed rail network.

A Breakthrough in Tunnel Reinforcement: The DGW551 Single-Arm Bolting Rig

The DGW551 is a next-generation, multi-functional tunneling rig tailored for the demanding needs of railway tunnel construction. Engineered for both performance and safety, it represents a significant leap in automated underground equipment.

Key Advantages:

🔧 5x More Efficient Than Manual Work
Equipped with a single yet agile mechanical arm, the DGW551 can install a 4.5-meter anchor bolt in just 4–5 minutes, compared to over 20 minutes using traditional manual methods. Its expansive reach — up to 16 meters wide and 10 meters high — enables full tunnel cross-section coverage in one pass, eliminating the need for repeated manual climbing and positioning.

🧠 Smart Control with Built-In Intelligence
At its core is an advanced IoT-enabled control system that monitors bolt tension and installation quality in real time. If any abnormalities are detected, the system instantly issues alerts. Every bolt’s data is recorded and traceable, ensuring uncompromising safety and construction transparency.

🛡️ Enhanced Operator Safety
Operators control the rig from a safe distance of up to 20 meters using a wireless remote. This drastically reduces the risk of injuries from rockfalls or working at height. Additionally, the system actively monitors geological stability and will automatically shut down if dangerous conditions are detected — acting as a “safety lock” for tunnel worksites.

🌱 Eco-Friendly & Energy-Efficient
Powered by a diesel-electric hybrid system, the DGW551 runs primarily on electricity for zero-emission performance, only switching to diesel in emergencies. It consumes up to 30% less energy than conventional rigs. A high-efficiency dust collection system keeps particulate emissions below half of national standards, ensuring cleaner worksites and protecting worker health.

Pioneering Tunnel Equipment, Proven on National Projects

As a veteran in the field of tunnel construction equipment, XCRUSHER DG’s bolting rigs have already been deployed on multiple high-profile infrastructure projects across China.

Looking Ahead: Smarter, Greener Construction

Committed to intelligent construction, XCRUSHER DG is pushing boundaries further by developing AI-based geological recognition systems in partnership with leading universities. Future models will autonomously adapt drilling strategies to surrounding rock conditions. The company is also working on interconnected operation modes, enabling its bolting rigs to operate in synergy with other tunneling machinery, much like a production line. By 2027, XCRUSHER DG plans to introduce a hydrogen-powered model, aiming for zero-emission tunnel construction.

This equipment delivery marks a new milestone for XCRUSHER DG in supporting sustainable rail infrastructure. The company will continue to empower global transportation with intelligent machinery, accelerating the arrival of more “mega-projects” around the world.
