TZ2A Double-Boom HydraulicPilot Drill Jambo 1、Main Applications It’smainly applicable for the tunneling operations of roadways and tunnels in minesand other underground projects.
Capableof drilling of blast holes, anchor rod holes, and undermining holes andinstallation of explosives, anchor rods, and air ducts.
Maximumoperation area coverage:72㎡.
2、Technical Features (1)Drill Jambo Thehydraulic drill jambo adopts special structural process on the basis of thedomestic tunneling process to realize super-strong anti-bending capability,high drilling speed, and low drilling tool consumption and effectively improvethe working performance of tunnel side hole drilling.
(2)Propeller Thelightweight high-strength alloy girder features high anti-bending,anti-distortion, and anti-fatigue performances and longer life.
(3)Chassis It’sapplied with energy-saving, environmental-friendly, and low emission engine,powerful all-road all-drive self-adaptive traveling system, integral frame, andrear-wheel steering system, featuring high vehicle stability.
(4)Drill boom Theall-directional paralleling-maintained drill booms of proprietary technologyfeatures accurate positioning. The drill booms adopt equal-strength structuredesign to realize reasonable structure, high strength, and long life.
(5)Drilling system Theautomatic anti-seizure, anti-empty-drilling, and automatic return functions ofdrilling tool are provided to effectively improve the drilling efficiency.
