Blast Hole Drill Rig Model HJG-B140INTRODUCTION:HJG-B series
open-air blast hole drilling rig is a combustion engine driven
crawler-type hydraulic drilling rig developed by our company,
adopting self-propelled hydraulic track chassis with favorable
mobility and equipped with high-power hydraulic motor, heavy
hydraulic drill boom and high air pressure DTH Hammer. The use of
drilling rig HJG-B140 mainly covers strip mining, road construction
and rock-drilling process in the field of water-power engineering.
It is a down-the-hole drilling rig specially designed for open
mine, stone pit and construction industry.HJG-B series open-air
blast hole drilling rig adopts diesel engine. Hydraulic oil pump
unit offers power to hydraulic motor moving, turn-around,
propulsion and lifting, and angle orientation of oil cylinder, etc.
When drill is working, only the down-the-hole hammer consumption of
fuel is saved by 40% to 50%. ADVANTAGES:1. All hydraulic
control, low purchase costHoist & feed system and rotary head are
both driven by hydraulic power with easily operating. Its drilling
can use low or high pressure compressing air, saves 1.5 times air
volume as contrasted with the drill by air-driven. It can reduces
the total cost of drilling.2. High efficiency, energy saving.The
drilling rig power is less than the drilling rig by air-driven,can
save more than 10 liter in one working hour, supply more turning
torque and feeding & hoisting power with hydraulic driven motor. It
is better used for hammer of 90-165mm to smash and flake rock.3.
Good stability.Succinct mechanical arm, decreasing the sliding
frame joint, when drilling blast hole the drill can have better
stability.4. Favorable agility and flexibility.The drilling rig is
a combustion engine driven hydraulic crawler drilling rig, adopting
self-propelled hydraulic track chassis and equipped with high-power
hydraulic motor, can have better agility and performance through
the floating joint of framework. 5. EngineCummins 100 hp
engine special for industry, to drive hydraulic pump and motor
which provide strong power for all actions of the machine.6. Rotary
headHydraulic rotary motor supply strong power, maximum rotary
torque can reach 4500NM, equipped with enforced absorber, eliminate
the back force from the hammer effectively to protect the motor and
speed reduction box.7. Hoist & feeding systemUsing strong linkage
chain system, driven by hydraulic motor, supplying 15000N lifting
force, it can rapidly feed and lift to save assistant time and
improve the drilling efficiency.8. Control boardControl handle
centralized control, easily operating, the operator can operate the
drill at the side of the drill. It improves the safe factor.9.
UndercarriageHigh-power hydraulic motor has great moving driving
force and high grade-ability to pull the air compressor. It is
operated flexibly and is convenient for working. The crawler
undercarriage floats within the range of 15°tilting gauge, which is
suitable for the construction in cragged field. The crawler which
is used for project and machinery is firm and durable.10. Air
filter and fuel tankTwo-stage air filter can filter over 90% of
dusts in the air inflow and discharge them automatically with no
cleaning, which can effectively reduce the abrasion of engine,
prolong the lifetime, enhance the efficiency and be used in various
severe working conditions.160 liter fuel tank ensures one working
day supplying. PARAMETERS:ModelHJG-B140HJG-B165Hole
