Drilling Diameter: 90 - 355 mm
Drilling Depth: 0-200 m
Mobility Type: 4 wheels trailer,front wheels with steering
Drilling Method: Air Drilling & Mud Drilling
>> Application
The TWD200 drilling for groundwater can use air, foam or mud rotary for percussive drilling according to different textures.
It is widely used in industrial and agricultural water conservancy projects, such as drilling wells, testing wells or other exploration boreholes.
In particular, in drilling hole for geothermal heating it can also meet the engineering basis for reinforcement, loose gravel drilling rock formation connected with a variety of engineering.

PRODUCT DESCRIPTION
TWD200 series trailer mounted drilling rig can drilling in all kinds formations by mud drilling in soft formation and air DTH hammer in rock drilling,DTH Hammer is applied in rock drilling, slag is discharged by air pressure and the offstage efficiency is ten times than traditional rotary drilling.
>> Characteristics
>> Centralized control console is suitable for each manipulation and control. Rapid pulling and lifting reduce the auxiliary time and enhance the work efficiency.
>> The main drive system, the transfer case, gearbox, double-winch unit, mud pump, turntable,drilling tower, feed system are set up on the chassis.
>> It's a hydraulicrotary drilling rig with directional circulation. It can equipped with BW 160/BW250/B2450 mud pump which adopts the slurry as the washing fluid and can drill on clay, sand and rock if it is equipped with suitable drilling bit.
>> The power of drilling rig comes from a diesel engine,High power diesel engine drives the large displacement high pressure plunger pump and it is characterized by powerful dynamic and stable performance.
>> The rotary head,have two gear,rotation speed is 0-80 and115rpm stepless adjustment and the drilling rigs with high rotary torque.
>> The pulling force can be regulated and controlled, which adapt the machine to deep hole drilling.
>> It can set up a generator which is convenient to welding or illuminate for work at night.
>> Main winch are available on the rig so it is high efficiency when the rig drill on mud rock and on the weathering formation.
