TZ3A Three-Boom Hydraulic Pilot Drill Jambo

1、Main Applications

It’s mainly applicable for the tunneling operations of roadways and tunnels in mines and other underground projects.

Capable of drilling of blast holes, anchor rod holes, and undermining holes and installation of explosives, anchor rods, and air ducts.

Maximum operation area coverage: 180㎡.

2、Technical Features

（1）Drill Jambo

The hydraulic drill jambo adopts special structural process on the basis of 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.

（2）Propeller

The lightweight high-strength alloy girder features high anti-bending, anti-distortion, and anti-fatigue performances and longer life. 

（3）Chassis

It’s applied with energy-saving, environmental-friendly, and low emission engine, powerful all-road all-drive self-adaptive traveling system, integral frame, and rear-wheel steering system, featuring high vehicle stability.

（4）Drill Boom

The all-directional paralleling-maintained drill booms of proprietary technology features accurate positioning. The drill booms adopt equal-strength structure design to realize reasonable structure, high strength, and long life.

（5）Drilling System

The automatic anti-seizure, anti-empty-drilling, and automatic return functions of drilling tool are provided to effectively improve the drilling efficiency.
