Mobile drill rigs PBU - 2 with a set of drilling and back-up
tooling are used for drilling different holes in rocks of up to the 4th
drillability index. The basic drilling method is rotary by floating spindle.
Mobile drill rig performs augering, augering of bore holes inclusive,
fluid or "dry" core drilling, cable tool percussion drilling. The rig can be
used in engineering geology and groundwater survey, water-well drilling, mineral
exploration and seismic survey.
Floating spindle of the rig is rotated
by the main shaft via the rig transmission and is moved along the mast guides by
feed unit cylinders. The mast is tubular, open faced. The draw works is planet
with free fault for cable tool percussion drilling, line capacity - 60 m, line
diameter - 14 mm. The rig without the draw works is used when well-casing is not
required, without cable drilling tool. The rig can be equipped with crank beam
of 550 mm walking beam stroke.
The rig with the beam allows to operate
with cable drilling tool, to perform withdrawal tests and driving.
The
rig can be used in penetration surveys with tool squeezing by 8 ton-force
floating spindle or by a special 10 ton-force carriage.
Options
Upon a customer's request NB-160\63 pump and 2VU 0,25 - 0,6\16
compressor can be supplied with a drive coming from the common transmission. The
option with the pump makes hole flushing, fluid core drilling possible. With the
compressor it is possible to build boreholes with cored screws and pneumatic
submerging of charge to the bottom of the hole when doing seismic survey.
Tools for different drilling technology can be supplied. The rig can be
mounted on different vehicles that are selected depending on the locality and
conditions where the rig is supposed to operate (ZIL-131, URAL-4320, TRUCK-Z -
4310, GAZ - 66,sledge transport, ТТ- 4 tractor, other types of chassis of load
carrying capacity more than 4 tons can be used)
