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¡ªway 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¡ªgear pump, less power loss, lower oil temperature, more stable working condition.
8¡¢ Equipped with a hand¡ªshaking 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.
