YGL-500 Reverse Circulation Drilling Rig
Applications：
YGL-500RC is mounted on a crawler chassis,driven by full hydraulic system, power head type drilling rig, which is used to drill vertical or inclined hole, and also the drilling techniques way of the following:
Drill auger drill
Down-The-Hole hammer drill
Mud forward circle drill
ODEX tools(casing pipe following) drill with DTH hammer
Medium reverse circle dril
The drilling rig is able to resolve the difficulty of boring in the soft and loose cover ground condition, the screes and gravels area and also the fragmentation stratum according to different drilling techniques ways. Therefore, it is widely used in varieties of the boring work.
The drilling rig is mainly applied in RC drill/water well and observation well, geothermal hole,mini foundation pile hole.
Features：
The rig has large output torque and wide speed range, which can meet various drilling methods and has a wide range of applications.
The rig’s feeding stroke is large, with no active drilling rod, which reduces the auxiliary time of reducing or adding rod, so that can improve the drilling efficiency.
The rig’s thrust force and lifting force are very large, which can meet the effective drill and have a super ability to handle accidents.
Important hydraulic parts on the drilling rig are selected from the world high-end technical products or well-known brand products, and the corresponding monitoring system is configured to ensure the good reliability of the system and the low failure rate.
