Hard rock DTH hydraulic rotary drilling rig for borehole water well 
>> Introduction
CWD260T Multi-functional track mounted water well drilling rig is a efficient,multi-function full hydraulic water well drilling rig.It is high efficiency because of having a larger torque of the turntable and is mainly used for water well in industry and agriculture, national defense building foundation, geological exploration, geothermic well and other foundation working, it is popular at home and abroad.
CWD260T Crawler 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.
CWD260T deep water well drilling rigs, in cutting drilling or rotary drilling can be operated in unconsolidated layer, and the slag can be discharged under by mud, the impact drilling operation can also be adopted and slag can be discharged by pressure air, the hydraulic water well drilling rig suitable for drilling complicated geological conditions.
>> Characteristic
>> The drilling rig can use air DTH Hammer drilling and mud drilling.
>> 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 hydraulic rotary drilling rig with directional circulation. It can equipped with BW450 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 Yuchai engine,73kw Yuchai 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 45-115rpm stepless adjustment and the rotary torque is 5000-6500Nm.
>> 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.
>> The main drive of rig is hydrulic and the four landing legs and drilling tower are hydraulic controlled. Transfer case and mud pump clutch system are also hydraulic operated.
>> Competitive in price, low cost of maintain.
