2018 Hjg Drilling Blast Hole Rock Drilling Tools Hjg-B140 Drill Rig

Blast Gap Drill Rig Model HJG-B140

HJG-B collection open-air blast gap drilling rig is a combustion engine pushed crawler-sort hydraulic drilling rig produced by our company, adopting self-propelled hydraulic observe chassis with favorable mobility and equipped with large-energy hydraulic motor, large hydraulic drill increase and large air force DTH Hammer. The use of drilling rig HJG-B140 mainly handles strip mining, highway development and rock-drilling approach in the field of water-electrical power engineering. It is a down-the-hole drilling rig specifically developed for open up mine, stone pit and construction business.

HJG-B collection open-air blast gap drilling rig adopts diesel motor. CZPT oil pump device provides energy to hydraulic motor shifting, switch-close to, propulsion and lifting, and angle orientation of oil cylinder, etc. When drill is functioning, only the down-the-gap hammer consumption of gasoline is saved by 40% to 50%.

Positive aspects:
one. All hydraulic manage, minimal acquire value

CZPT & feed method and rotary head are equally pushed by hydraulic power with simply working. Its drilling can use lower or higher strain compressing air, saves 1.5 times air volume as contrasted with the drill by air-pushed. It can lowers the overall cost of drilling.

two. Large effectiveness, power saving.

The drilling rig energy is considerably less than the drilling rig by air-driven,can help save a lot more than ten liter in one operating hour, supply more turning torque and feeding & hoisting power with hydraulic pushed motor. It is far better used for hammer of 90-165mm to smash and flake rock.

3. Great balance.

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

4. Favorable agility and versatility.

The drilling rig is a combustion motor pushed hydraulic crawler drilling rig, adopting self-propelled hydraulic monitor chassis and geared up with high-electrical power hydraulic motor, can have better agility and functionality by way of the floating joint of framework.


5. Motor

CZPT 100 hp engine special for business, to travel hydraulic pump and motor which provide powerful electricity for all actions of the device.

six. Rotary head

CZPT rotary motor source strong energy, optimum rotary torque can achieve 4500NM, equipped with enforced absorber, eradicate the back again pressure from the hammer properly to protect the motor and velocity reduction box.

7. CZPT & feeding method

Employing robust linkage chain program, pushed by hydraulic motor, providing 15000N lifting force, it can quickly feed and raise to save assistant time and boost the drilling performance.

eight. Control board

Manage take care of centralized manage, very easily working, the operator can function the drill at the facet of the drill. It improves the secure issue.

9. Undercarriage

Large-power hydraulic motor has excellent shifting driving pressure and substantial grade-capability to pull the air compressor. It is operated flexibly and is practical for working. The crawler undercarriage floats inside of the selection of 15°tilting gauge, which is ideal for the construction in cragged field. The crawler which is utilised for undertaking and machinery is company and durable.

ten. Air filter and gas tank

Two-stage air filter can filter more than 90% of dusts in the air inflow and discharge them routinely with no cleaning, which can effectively minimize the abrasion of motor, extend the life time, boost the efficiency and be used in different significant functioning conditions.one hundred sixty liter gasoline tank makes certain 1 operating working day supplying.
