- Long spindle stroke which increases the drilling efficiency as well as reducing the occurrence of accidents during drilling.
- Wide range of adjustable speed, allow speed verifying continuously and stable speed control.
- Suitable in drilling constructions requiring diameters such as PC, HC, NC and BC.
- Independent control panel, simple operations, has meters monitoring the operation of the whole machine and the working conditions in the hole.
- Hydraulic control achieved by clamper, mud pump and blender.
- Reliable core components. The hydraulic pumps, valves and motors of the machine are from well-known manufacturers.
- Large pulling force of the feeding oil tank, feeding stroke 4.8m, suitable for 3meters and 4.5meters cables.
- Ensure full-pipe coring can be completed at one time, increasing the coring rate.
- Mechanical gear shifting and hydraulic speed control are integrated and the application of electronic digital display can achieve 0-1200 rpm continuous speed verifying and precise control of the rotational speed of the power head.
- Safe and reliable hydraulic chuck. Built-in 5 piece of hard alloy slips. The maximum clamping force reaches 350kN. Guaranteed ease of detaching and replacement of slips with various specifications.
