Product Description:

Drill Jambo
The hydraulic drill jumbo adopts a special structural process based on the domestic tunneling process to realize super-strong
anti-bending capability, high drilling speed, and low drilling tool consumption and effectively improve the working performance of
tunnel side hole drilling.
The lightweight high-strength alloy girder features high anti-bending, anti-distortion, and anti-fatigue performances and longer life.
Drill boom
The all-directional paralleling-maintained drill booms of proprietary technology feature accurate positioning. The drill booms
adopt equal-strength structure design to realize reasonable structure, high strength, and long life.
Drilling system
The three-stage anti-seizure, anti-empty-drilling, and automatic return functions of the drilling tool are provided to effectively
improve the drilling efficiency and reduce the consumption of drilling tools.
Hydraulic system
The electronic control design is applied for the auxiliary motions, including outriggers and roof lamps to simplify the pipelines
and ease the maintenances.
