A2B drilling rig
on the basis of the original Northwest Wolf
On the basis of the original Northwest Wolf, the HWH group has upgraded and optimized the product operation table, propulsion beam, rotary head, shell parts, drilling arm parts and dust collecting parts, in order to maximize the performance of the drilling rig. The diesel engine has changed from the original horizontal to the vertical layout, making the position relationship between the components full of infinite possibilities. This model is simple in structure and cost-effective, especially suitable for all kinds of open-pit mines in northwest China.
| Engine | Adopt 58kw, national three diesel engine |
| Bore diameter | φ80-φ105mm |
| Optional air compressor parameters | Pressure：0.8-1.3mpa, air capacity：10-15m3/min |
Power components
◆Equipped with Yuchai four-cylinder national three diesel engine, with sufficient power to meet the latest national emission standards
◆Add antifreeze, strong adaptability to high altitude cold.
Using maintenance-free battery, easy to use, long life, excellent performanc.
◆Open design for easy maintenance and maintenance.
Rotary system
◆Motor direct connection, the rotary speed is more advantageous, cancel the high failure rate of the reducer, the rotary head is more durable, in line with the needs of most users.
Console
◆ control table directly front, cancel the rotating table, increase the operation space, replace the drill pipe convenient；
◆drill rod stock baffle is changed from the previous pin type to the knife type, and the operation is more humanized.
Electronic control system
◆LCDscreen display, high degree of integration, real, time monitoring of various parameters, can be intelligently switched according to the ring, environment and operating conditions of the working mode, type, and with self-diagnosis, alarm function.
Propulsion beam
According to the market quality feedback, a guide plate is added on the inside of the propulsion beam to ensure that the pulley frame will not run away when promoting the lifting；
Dust collection parts
◆The dust collector is installed within the scope of the track and is transported in an effective place
Drill arm part
◆The drilling arm moves forward and swings upward, increasing the movement range of the guide rail, and the drilling adaptability is better.
Chassis parts
◆Using the engineering excavator with four wheels, and equipped with crawler baffle, strong climbing ability, reliable and durable.
◆The plunger-type walking motor is used to walk with a stable and reliable condition.
