PRODUCT DESCRIPTION
TWD300B 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.
TWD300B 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.
>> Characteristics
>> The rotary head,have two gear,rotation speed is 45-115rpm stepless adjustment and the rotary torque is 3500-8500Nm.
>> 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.
>> The tools winch winch is used for auxiliary lifting and casin.
>> The Hydraulic auxiliary functions are easy and efficient for guide extension, boom swing, boom lift, guide dumping.
>> Competitive in price, low cost of maintain.
