 | Drilling rig UBG-SG |
Drilling rig hydraulically operated of intermediate class is designed for drilling engineering wells in the rocks of 1-12 drillability index, for making root and auger piles, land ties, dewatering wells, and other operations in close conditions of various buildings and in open grounds.
Opportunities and advantages of installation: High flotation ability and maneuverability of the tracklayer-mounted installation allows easy setup of center line of swivel head spindle relative to borehole axis in close conditions. Installation is specially adapted for making root and auger piles; with application of original tool that increase rate of work. The swivel head allows its drawing aside for safe handling of running-pulling operations with the use of hoist.
Original configuration of hydraulic system ensures low hydraulic pump flow when starting and operating the diesel engine, thus increasing efficiency and easy start at negative temperature of ambient air.
