The equipment adopts the patented antiskid outrigger of the Company, which can maximally satisfy 28° downhill tunneling engineering. By adopting the full-hydraulically driven single-arm, the drilling speed of the jumbo can reach 0.8-2 m/min. The system is convenient for operation, safe and reliable with the functions of automatic stop of impacting at destination, automatic anti-jamming and induction of slag in water drainage, etc. Due to the small size, compact structure, low gravity center and the adoption of rail-and-wheel traveling mode, the locomotive works flexibly and stably, with a strong gradeability. The complete machine has only one power supply mode, and the energy conservation and low noise can greatly improve the work conditions, and enhance the construction efficiency and quality. It is very suitable for the operation in narrow roadways.
