Features

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.
