Product Description

         B3 Open-air Down-the-hole Drilling Rig

Product Description

B3 integrated open-air down-the-hole drilling rig is a drilling equipment that integrates open-air down-the-hole drilling rig and screw air compression system, with compact structure, good integrity, and easy to move. The drilling rig has the characteristics of energy saving and high efficiency, safety and environmental protection, flexible maneuverability, convenient operation and stable performance. It is mainly suitable for rock drilling and blasting holes in open-pit projects such as mining and quarrying, road construction, water conservancy and electric power.

Product Feature 

Dual power system
It integrates a diesel engine and a high-power electric motor of two driving modes, and is more adaptable to the environment.

Control System
Imported intelligent control system, liquid crystal display interface and multi-language intelligent controller are easy to operate. The machine has self-diagnosing fault, alarm and shutdown protection functions.

Operating area
The drill arm part is equipped with a motor slewing support, which expands the amplitude range of the thruster and can effectively meet various operating requirements.

Walking system
The overall welded chassis, together with widened track link, has good stability of the whole machine, which is more suitable for walking in muddy places on construction sites, and is not easy to sink.

Dual rotary motor
It adopts dual motor gyrators and is equipped with manual rotary valves. The high-speed low-torque and low-speed high-torque can be adjusted to better adapt to different operating requirements.


Product Feature

The drill arm part is equipped with a double-motor slewing support, which expands the amplitude range of the thruster and can effectively meet various operating requirements.

Double oil cylinders are used to support the drill boom, greatly improving the stability of the drill boom, which is reliable, durable and adaptable.

The overall welded chassis is equipped with extended chain rails and widened track link. The stability of the whole machine is good, and it is more suitable for walking in muddy places on construction sites, and it is not easy to sink.

It adopts dual motor gyrators and is equipped with manual rotary valves. The high-speed low-torque and low-speed high-torque can be adjusted to better adapt to different operating requirements.

The electrical appliance is equipped with a soft start, which is easy to start and also protects the motor.
