Product Introduction


The two-stage boom configuration allows for adaptive height customization based on the tunnel profile, avoiding interference with top supports and geological structures, while maintaining operational adaptability across different working space heights during maintenance tasks.

The telescopic arm cylinder integrates a shielding internal mechanism and an enhanced protective device, providing strong protection for hydraulic components from impact damage during equipment operation.

The spatially optimized hydraulic layout adopts armored pipe wiring along the double channels of the suspension rods and uses wear-resistant sleeves to extend durability.

The high-performance hydraulic architecture can enhance the excavation capacity and achieve efficient material handling. The fluid circuit interface maintains constant pressure integrity through a precisely designed sealing solution.

The semi-shielded cab strikes a balance between panoramic visibility and reinforced structure, and combines modular roof panels and quick release functions, simplifying maintenance operations.

The power module adopts an integrated design with an impact-resistant cladding, reducing the vulnerability of debris intrusion, while achieving active thermal management through an optimized airflow circulation.

The 360-degree crushing tool ensures comprehensive material processing capabilities with no operational blind spots, and supports diverse task requirements through modular tool integration.

The electrically driven hydraulic network reduces acoustic characteristics and eliminates combustion by-products when in operation, and is specifically designed for closed underground mineral mining environments.
