Hjg Blast Hole Drill Rig Rock Drilling Tools Hjg-B140

Blast Gap Drill Rig Model HJG-B140

HJG-B collection open-air blast gap drilling rig is a combustion motor driven crawler-sort hydraulic drilling rig designed by our organization, adopting self-propelled hydraulic monitor chassis with favorable mobility and outfitted with large-electricity hydraulic motor, large hydraulic drill boom and substantial air force DTH Hammer. The use of drilling rig HJG-B140 mostly covers strip mining, highway design and rock-drilling process in the subject of water-electricity engineering. It is a down-the-gap drilling rig specifically developed for open mine, stone pit and development business.

HJG-B collection open up-air blast hole drilling rig adopts diesel engine. CZPT oil pump device delivers energy to hydraulic motor transferring, change-close to, propulsion and lifting, and angle orientation of oil cylinder, and many others. When drill is operating, only the down-the-hole hammer usage of gas is saved by 40% to 50%.

Positive aspects:
one,All hydraulic control, low purchase price

CZPT & feed system and rotary head are the two driven by hydraulic electrical power with easily running. Its drilling can use low or high stress compressing air, saves 1.five occasions air volume as contrasted with the drill by air-pushed. It can reduces the complete value of drilling.

two. High performance, strength preserving.

The drilling rig power is less than the drilling rig by air-driven,can conserve much more than ten liter in one working hour, provide far more turning torque and feeding & hoisting power with hydraulic driven motor. It is much better utilized for hammer of 90-165mm to smash and flake rock.

3. Great stability.

Succinct mechanical arm, decreasing the sliding frame joint, when drilling blast hole the drill can have better steadiness.

4. Favorable agility and versatility.

The drilling rig is a combustion engine driven hydraulic crawler drilling rig, adopting self-propelled hydraulic monitor chassis and outfitted with substantial-power hydraulic motor, can have better agility and overall performance through the floating joint of framework.


five. Motor

CZPT one hundred hp motor particular for industry, to generate hydraulic pump and motor which give powerful power for all steps of the machine.

six. Rotary head

CZPT rotary motor offer sturdy energy, highest rotary torque can achieve 4500NM, outfitted with enforced absorber, eradicate the back again drive from the hammer effectively to protect the motor and speed reduction box.

seven. CZPT & feeding program

Making use of robust linkage chain technique, driven by hydraulic motor, supplying 15000N lifting drive, it can speedily feed and raise to conserve assistant time and increase the drilling performance.

8. Handle board

Handle take care of centralized manage, easily running, the operator can run the drill at the facet of the drill. It enhances the risk-free aspect.

nine. Undercarriage

Substantial-electricity hydraulic motor has great moving driving power and large quality-potential to pull the air compressor. It is operated flexibly and is hassle-free for operating. The crawler undercarriage floats inside the range of 15°tilting gauge, which is suited for the construction in cragged field. The crawler which is used for venture and equipment is organization and resilient.

10. Air filter and gas tank

Two-phase air filter can filter more than ninety% of dusts in the air influx and discharge them instantly with no cleansing, which can effectively lessen the abrasion of engine, prolong the lifetime, improve the performance and be used in different extreme doing work circumstances.160 liter gas tank guarantees 1 working day supplying.
