HCR-8

Description

Developed on the basis of HYDX series rigs, HCR-8 truck-mounted core drill rig is an up-to-date and thoroughly new-typed drilling rig. This hydraulic core drilling rig is an ideal core drilling machine due to reasonable design, compact structure, excellent performance, easy operation, convenient maintenance, and so on. Therefore, this machine can be used to different construction sites, such as plains, hills, high temperature as well as low temperature places.

Features

1. The full hydraulic driving system of the rotary drilling rig is mounted on heavy-duty truck.
2. This truck-mounted core drill rig adopts mechanical 3-gear speed regulation as well as hydraulic stepless speed regulation.
3. The oil cylinder is working with a feed-in multiple-speed chain, thus, its feed-in and lifting performances are stable and reliable.
4. With the mast being erected and lowered with oil cylinder, it is foldable and has moving and ground-supporting functions.
5. The mast is adjustable in the range from 0° to 90° to ensure a proper hole-drilling angle. The low gravity center of the rig promises a steady operation. And the control panel provides the operators with a convenient and comfortable working circumstance and a wide view.
