Multifunctional Full Hydraulic Rig Anchor Drilling Machine 7m Feeding Stroke
1. YDL-300DT Hydraulic drilling rig with the feeding stoke of mast is 7m,this water well machine is used to deep water well hole project and seize the new market .It’s a new,efficient,energy-saving and multifunctional full hydraulic drilling rig.
2. The machine can use two 3m drill rods one time because of the 7m feeding stroke,it can reduce the time of adding drill rod,also can reduce the labour intensity.
3. It can pull casing pipe when drilling with casing and it is also suitable for small non-excavation construction because of two large cylinders on the mast and the lifting capacity can reach 25T.
The equipment,the drilling techniques way of the following:
a. Dry auger drill
b. Down-The-Hole hammer drill
c. Mud forward circle drill
d. Medium reverse circle drill
e. ODEX tools (casing pipe following) drill with DTH hammer
