Versatile crawler hydraulic wells-geothermal drill rig
HJG-W500NINTRODUCTION:HJG-W series rig is a versatile crawler
hydraulic wells-geothermal drill rig with internal combustion
driven, which is meticulously designed and lean manufactured in our
company. All the key parts of the rig are imported from foreign
country to ensure the stability of the rig function. The rig
maximum drilling depth is up to 300 meters, the hole diameter
105~254mm, can satisfy the different geological environment warm
engineering, groundwater, hydro geology exploration, piling
foundation and some other project required. The rig can replace
equal imported production and performance-price ration is more
outstanding. The whole machine has the advantages e.g. big power of
engine, big output torque, high working efficiency, flexibility,
good stability and multifunction, etc.ADVANTAGES: 1,Wide
application. High-performance and high reliability.HJG-W
series Wells Geothermal Drill rig is widely used in drilling
operation such as drilling well, geothermal air conditioning well
and exploration well, etc. In stone drilling, DTH hammer is applied
in the operation, slag is discharged by air pressure, the drilling
efficiency is ten times of the traditional rotary drilling. Cutting
drilling or cone drilling can be operated in the unconsolidated
layer, mud and slag can be discharged. The machine is suitable for
drilling in complicated geological conditions.2. Control
board.Control handle centralized control, easily operating, All
drilling operations are processed on platform which is set in the
left of wellhead. The operator can operate the drill at the side of
the drill. It improves the safe factor.3. Engine.The driving system
is diesel engine driven. Cummins 125 hp engine special for
industry, drive hydraulic pump and motor which provide strong power
for all actions of the machine.4. Undercarriage.The drill rig
adopts self-propelled hydraulic track chassis which is
reinforcement durable. Track shoe is especially widened and that
effectively increases stability and maneuverability of drill rig
working on soft and muddy ground. Four hydraulic cylinder legs
which controlled separately keep the rig with high drilling
accuracy.5. Rotary head.The torque of power rotary head driven by
imported double hydraulic motor is up to10000Nm, which can adjust
the rotary speed of 0~150 rpm.6. Hoist & feeding system.The
combination of the oil cylinder and the wire rope provides strong
driving force for the system. The sliding rank with newly designed
structure, the compensation structure and the drilling frame
provides strong support and long life time.7. Winch
system.Hydraulic motor-powered winch can flexibly hoist less than
one and a half tons of drilling tools or accessories.8. Wrench
hydraulic cylinder.Hydraulic cylinder-powered wrench can
disassemble all kinds of joints quickly and lighten labor
intensity.9. Air filter.Two-stage air filter can filter over 90% of
dusts in the air inflow, which can effectively reduce the abrasion
of engine, prolong the lifetime and be used in various severe
working conditions.10. Footplate.The operator can stand on the
footplate with enough areas avoiding mud under
feet. PARAMETERS:ModelHJG-W300CHJG-W500NHJG-W500CAperture105-254
