300m crawler diesel water well drilling rig
This drilling rig is suitable for water well drilling, survey exploration, geophysical exploration, road and building exploration, as well as drilling blasting holes and other drilling projects.
Description
Main features
- Equipped with hydraulic automatic feed mechanism, it improves drilling efficiency and reduces labor intensity.
- By using a ball clamp clamping mechanism instead of a chuck, it is possible to achieve non-stop rod reversing, which is convenient to operate and safe and reliable.
- Equipped with a bottom hole pressure gauge for easy control of the situation inside the hole.
- Compact structure, concentrated handle, small footprint, light weight, strong decomposability (to be reassembled on site), and easy to relocate. Suitable for work in plains or mountainous areas.
