THJ-2000
It is suitable for coalfield, geological, hydro-geological, metal ferrous and non metal ferrous hole drilling engineering, also for drilling and exploration underground water resource, shallow petroleum, natural gas and geothermal.
1、 With patent“active drilling hydraulic spring clamp”(patent No. ZL20092 0254556.8), which is property right owned, convenient active drilling can be realized.
2、 Hydraulic chuck adopting a two—way oil supply means and equipped with hydraulic. It has a powerful clamping force.
3、 Vertical shaft with spline transmits larger torque and provides longevity.
4、 Equipped with adjustable water brake, makes the landing of rods more smooth and safe when drilling deeply.
5、 With transverse winch, wrong roping can be avoided; longevity of the rope can be acquired.
6、 With belt type brake, more powerful braking force and longevity of brake belt can be provided.
7、 It uses dual—gear pump, less power loss, lower oil temperature, more stable working condition.
8、 Equipped with a hand—shaking oil pump, it can lift the drill up in order to avoid an underground accident when the power operating failed.
9、 Low gravity center, a long traveling distance, a reliable fixation and a good stability in high speed drilling.
10、Its power may be motor or diesel and optional for customers.
