Three-Arm Arch Support Installation Trolley ZXGJ2800

Three-Arm Arch Support Installation Trolley ZXGJ2800

The ZXGJ2800 three‑arm vertical arch‑erection trolley is a new‑generation tunnel‑construction machine developed by our company. It integrates multiple functions—including arch‑frame installation, mesh‑and‑rockbolt placement, and auxiliary drilling—enabling “one machine, multiple uses” and reducing equipment investment. The machine employs an innovative vertical‑erection process, allowing it to install 2–3 precast welded arch frames in a single operation, thereby completely addressing the time‑consuming, labor‑intensive, and high‑risk challenges of traditional manual erection and meeting the demands of mechanized, rapid construction. Product features: - Wheeled engineering chassis: 123 kW diesel engine, four‑wheel drive, dual steering axles, and three travel modes; bi‑directional cab with automatic rear‑wheel alignment for safe, flexible, and stable operation. - Transmission system: hydraulic torque converter + gearbox + heavy‑duty axles, ensuring reliable braking and low failure rates. - Diesel‑electric hybrid power: zero emissions, low noise, and reduced operating costs during operations, fully compliant with environmental standards. - Three‑arm high‑efficiency operation: equipped with three arms, three grippers, and three suspended work platforms, it can install 2–3 precast arch frames per cycle, significantly shortening arch‑erection time. - Intelligent safety and wireless remote control: prevents operator error, simplifies operation, and enhances safety and ease of use. - Wide‑range adaptability: suitable for all types of tunnels, including high‑speed rail single‑ and double‑track tunnels constructed using full‑face or bench‑method techniques, and compatible with certain highway tunnels.

Three-arm rock drilling rig ZXZY310

Three-arm rock drilling rig ZXZY310

The ZXZY310 three‑arm rock drilling rig features rapid iterative upgrades on the job site. Leveraging a modular design, it allows flexible reconfiguration of functional components at the construction site, quickly adapting to customized tunnel‑construction configurations without requiring return to the factory for modifications, thereby significantly shortening equipment adaptation cycles. Following comprehensive optimization of the machine’s powertrain and drilling system, wear on key drill components such as drill rods and bits is effectively reduced, continuously lowering consumable‑related costs. The rig’s overall scene compatibility has been comprehensively enhanced, enabling it to handle tunnel conditions across varying cross‑section sizes, surrounding rock grades, and operational environments. It can reliably and efficiently undertake large‑ and medium‑scale projects—including railway tunnels, highway tunnels, defense‑related tunnel works, water‑conservation diversion tunnels, and underground mine roadways—meeting the drilling requirements for blast‑hole, anchor‑hole, and grouting‑hole operations in drill‑and‑blast tunneling, thus ensuring continuous, efficient progress of tunnel excavation. Product highlights: - **All‑scenario construction adaptability**: Specifically engineered for underground engineering and tunnel‑excavation operations, this rig efficiently addresses complex underground drilling needs and is compatible with railway, highway, mining, and other types of tunnel projects. - **Outstanding off‑road capability**: Equipped with a wet‑type drive axle and a four‑wheel‑drive locomotion system, along with an integral engineering‑grade chassis, it delivers exceptional gradeability, effortlessly navigating tunnel ramps, muddy terrain, and other challenging conditions while ensuring agile and efficient relocation. - **Precision hydraulic control**: Featuring an electro‑proportional pilot‑control‑based hydraulic system, it offers stable, reliable operation, smooth feedback, and flexible adjustment of parameters to meet diverse precision requirements. - **Smart, efficient operation**: With built‑in automatic anti‑jamming and automatic lubrication systems, it maintains high drilling efficiency, dramatically reduces tool consumption, minimizes equipment downtime for maintenance, and enhances overall construction continuity. - **Streamlined supporting infrastructure**: Incorporating integrated water and cable reels, it eliminates the need for external auxiliary equipment, simplifying operations, saving labor, cutting on‑site preparation time, and boosting overall productivity.

Two-arm rock drilling rig ZXZY210

Two-arm rock drilling rig ZXZY210

The ZXZY210 twin-arm rock‑drilling rig is designed for high-speed rail and highway tunnel construction, supporting multi‑stage simultaneous excavation, step‑by‑step methods, full-face excavation, and invert arch construction. It overcomes the limitations of conventional equipment that cannot accommodate multiple construction techniques, delivering superior performance when two units operate side by side in medium‑ to large‑size tunnels. Product features: - National Stage IV‑compliant powertrain: energy‑saving and highly efficient. - Versatile applicability: a true all‑method rock‑drilling rig, suitable for full‑face, step‑by‑step, and invert arch operations. - Dual operation modes—local control and remote control—for flexible, convenient handling. - Sturdy chassis with dual‑tire front axle design: ensures smooth, reliable travel. - Dual‑rotation drill‑arm structure: provides stable, precise positioning and enhanced efficiency. - Built-in angle display: enables accurate control of over‑ or under‑excavation.
