Electric Bolting Rig

Product Introduction

The Electric Bolting Rig is a core support equipment for underground engineering such as mining, tunneling and water conservancy. Its core functions are to mechanically drill bolt holes / anchor cable holes and install bolts / anchor cables, so as to reinforce rock masses and stabilize roadways. It replaces manual support, ensuring construction safety and efficiency.

Parameters

Application Scenarios & Functions

Application Scenarios

●Roadway support in coal mines, metal/non-metal mines; 

●Anchoring for highway/railway tunnels, hydraulic caverns and deep foundation pits; 

●Roadway repair, reinforcement, and construction of water detection/gas detection boreholes.

Core Functions

Integrated operation including full-section drilling on roof, ribs and floor, automatic bolt installation, mesh hanging and grouting.

Advantages

• Strong Passability & Adaptability

  Equipped with a steel crawler chassis with strong climbing ability (±16°), it can travel stably in muddy, rough and sloped roadways, adapting to complex underground working conditions.

Stable & Efficient Operation

• Low center of gravity and hydraulic outriggers ensure stable drilling with high hole-forming accuracy. Multi-arm simultaneous operation allows multiple rows of holes to be drilled in one positioning, increasing support efficiency by more than 50%.

• High Maneuverability & Flexibility

  Compact structure and small turning radius make it suitable for narrow roadways (minimum section 5㎡), with easy relocation and movement.

• Low Operating Cost

  Electric drive and full hydraulic control enable effortless operation and low failure rate.

Training

To help improve the standard operation and working efficiency of Electric Bolting Rig, our company provides customized special training for operators, maintenance personnel and safety managers. The whole training adopts a mode of theoretical instruction + practical operation + assessment.

Risk points are analyzed based on actual violation cases in underground mine operations. The practical session uses a 1:1 simulated underground working environment, with instructors providing hands‑on guidance for drill boom positioning, drilling, bolt installation and emergency stop operations. Key procedures such as drill rod replacement and hydraulic hose pressure relief are repeatedly practiced, and mutual evaluation is arranged during practical training. An assessment is organized at the end of the training to ensure all participants are fully qualified.

Customer Feedback

Customer feedback after the training:

“This training closely matches on-site working requirements. The instructors explained in detail and provided thorough practical guidance. Problems we encountered before, such as inaccurate drill boom alignment and difficulties in troubleshooting, have all been resolved. Even new operators can master the skills quickly. It has not only improved operating skills but also strengthened safety awareness, providing a strong guarantee for efficient and safe underground operations.”

Benefits Delivered

The Electric Bolting Rig has significantly improved underground support efficiency:

• ●Single-cycle time reduced by 50%

• ●Operating personnel reduced by 50%

• ●Support qualification rate increased to 99.5%

Mechanized operation reduces the risks of roof exposure work and lowers labor intensity. Precise construction cuts material waste by more than 15%, extends roadway service life, reduces maintenance costs, and accelerates tunneling progress, achieving simultaneous improvements in safety, efficiency and cost.

• Advantages as a Direct Manufacturer

• Technology & Customization

  Independently developed with core patents. Models can be customized according to roadway cross-section, rock formations and support technologies to adapt to special working conditions.

• Quality & Cost Efficiency

  Directly controlled supply chain, with core components self-produced or strictly selected for stable quality. No middlemen, resulting in higher cost performance and shorter delivery lead time.

• Service & Support

  Full-process service including pre-sales solutions, in-sales training and after-sales maintenance. Fast response with sufficient spare parts.

• Qualifications & Compliance

  Certified with MA mining safety certification, ISO9001 and other qualifications. Products comply with industry standards and are adaptable to certifications for export to multiple countries.

• Iteration & Upgrading

  Continuous R&D investment enables fast product iteration. Intelligent upgrades such as remote control operation and data monitoring are available.
