Introduction
Spindle core drill rig makes use of rotary action of drill bit to cut and crush rocks. It is particularly suitable for engineering geological investigation for construction of railways, bridges, hydro-power stations and dam foundations. Core drilling machine is also used for drilling small grout and blasting hole, small water well, etc. Besides, this drill rig can be applied in geological core drilling and geophysical survey as well.
Feature
1. Spindle core drill rig is installed with hydraulic feeding mechanism to increase work efficiency and reduce labor intensity of workers.
2. With down hole pressure gauge, it is convenient to examine the down hole condition.
3. The control handles of core drilling machine are arranged for the convenience of operation.
4. Spindle core drill rig has features of compact structure, small size, easy dismantlement and light weight. It is fairly suitable for operation in plain areas as well as mountainous areas.
5. It is equipped with a clamp-up device and drill rod which can be changed without stopping drill rig. Thus, reliable and safe operation can be achieved.
