MDL-135H CRAWLER ANCHOR DRILLING RIG
Quick detail:
1. MDL-135/150H drilling rig is a kind of full hydraulic multifunctional power head crawler drilling rig. It is mainly applied in anchoring hole of deep foundation,urban subway,slope supporting, tunnel,high building,airport,geothermal construction,pipe shed and so on.
2. The route of shaft bracket is 3.4 meters, so the 150H crawler anchor drilling rig can have complex rod & casing drill for 3 meters. The rig is applicable to rod boring, casing drilling and complex rod & casing drilling.
3. MDL-135/150H crawler drilling rig has level system (drill arm) is able to adjust mast in different angle and height without moving drilling rig, This can adjust to the max level of 3.3m.
4. The big arm like excavator with double cylinders has the stability of any lifting condition.
5. The crawler from the ground space is so large to adapt for bad environment construction.
6. The hydraulic clamp & wrench device enormously decreases the assistant time and also reduces the intensity of operating work.
