| 1.Range of applications |
|
XY-1B Drill Rig is a hydraulic-feed core drill. |
|
(1)Engineering geological explorations for railway, hydro-power, highway, bridge and dam etc. |
|
(2)Geologic core drilling and geophysical exploration. |
|
(3)Drill the holes for small grouting, blast and small water well. |
|
4)Diamond bit, hard-metal bit and steel shot could be selected according to different layers. |
|
(5)The hoist spindle is supported by the ball bearing, it could eliminate the event of the supporting bearing. |
|
(6)Under the spindle head, there is a well top plate which provides the convenience for unscrew the rods. |
|
(7)Compact size and light weight are easy to dismantle and transport, adapts to work in plain and mountain areas. |
|
2.Feature |
(1)Adopting the hydraulic feed mechanism, with which could increase the drilling efficiency and reduce the manpower. |
(2)Being equipped with ball type holding device and hexagonal Kelly, it can accomplish no-stopping working while lifting the rods and get a high drilling efficiency. |
(3)By the pressure indicator of bottom hole, the well condition can be observed easily. |
(4)Close levers, convenient operation, security and reliability |
(5)The hoist spindle is supported by the ball bearing, it could eliminate the event of the supporting bearing. |
(6)Under the spindle head, there is a well top plate which provides the convenience for unscrew the rods. |
(7)Compact size and light weight are easy to dismantle and transport, adapts to work in plain and mountain areas |
