1.Triple pitch, double swing, and 360° rotation from the boom to the propulsion beam ensure positioning at any position and angle within the working section.

2. The combination of boom extension + propulsion beam translation     + propulsion beam compensation, and basic actions of the jumbo make the positioning of the blast hole faster and more accurate.

3.The lifting and lowering of the protective cover can be adjusted freely, ensuring safety and convenience.The cable reel automatically retracts and releases cables, making it convenient and efficient.

4. The fully hydraulic steering wheel steering, eight action four bar operation for gun hole positioning, seven pressure gauges for all-round monitoring, and the independently developed hydraulic system of the rock drill can match any domestically imported rock drill. The hydraulic logic antijamming mechanism is sensitive and reliable.

5. The joints of the entire vehicle are made of high-strength cast steel, which is beautiful and reliable, and the positioning of the blast holes is more stable.
