FD850A

FD850A rotary drilling rig is an industry-proven drilling solution to handle sand, clay, pebble bed and weathered rock layer, etc. This series of drilling machine is the tool of choice for engineering projects such as high-rise buildings, bridges and roads, delivering exceptionally stable boreholes.

Our rotary drilling rig has a wide range of drilling diameter which is variable from 600 to 1600mm. Moreover, this deep foundation machine stands out from other competitors in terms of efficiency, for it normally uses 3.5 to 4 hours to form a borehole. The maximum depth reaches 46m!

Advantage
1. Folding mast is employed for compact and simple structure. As a result, superior durability is enhanced to provide lower cost and maintenance.

2. Guide frame is mounted on the top to make sure that the drilling rod is always vertical to ground. Therefore, customers benefit from extraordinary drilling efficiency and safety.
