Main features:
1. The well drilling rig machine improves drilling efficiency and reduces labor intensity with hydraulic automatic feeding mechanism.
2. The well drilling machine can be achieved without stopping to change rods, easy to operate, safe and reliable with ball clip holding mechanism or hydraulic chuck.
3. The deep water well drill rig has hole bottom pressure gauge to be easy tp master the situation in the hole.
4. The borehole drilling machine also has advantage of compact structure, concentrated handle, small footprint, light weight, strong decomposition, easy to move.It can be operated in plains and mountain areas.
Crawler Hydraulic DTH Drilling Rig Machine
- The TMZ1250 drill rig is designed for working in narrow spaces, such as tunnel, culver and foundation ditch.
- With its rotating-percussion rotary head, it is suitable for drilling in stratum formations of sticky clay, sandstone as well as partially decomposed rock stratum.
- With down-the-hole hammer, it can drill in hard rock formation efficiently. The emission standard of its power engine is TIERIII.
- With 360 degree horizontal and vertical rotating tables it can be used efficiently for drilling holes to front facet, flank facet as well as ceiling of tunnels.
- In the operation panel a special designed operation handle for shifting to grout jetting drilling technique, with suitable rotating and pull back speed for high efficiency grout jetting.
