Studies of snow cover, avalanches, glaciers, permafrost, seasonal ice of fresh or salt water basins, and
extraterrestrial ice formations are usually conducted in extreme working environments.
Field operations in such environments can benefit from compact equipment in 3 key aspects: increased safety
of
field operations, reduced physical burden for the staff, and minimized transportation costs for equipment
and samples.
And, of course, weight and size savings cannot compromise efficiency and reliability of equipment.
Medium
series rig
About
Intermediate depth wireline drilling rig is designed for operating electro-drills and borehole
logging
devices with power requirements up to 5 kW and up to 4 fiber optical communication channels.
Depending
on
cable diameter it can be configured for drilling or logging boreholes up to 750 m deep. The winch is
powered
with 1 kW DC brush motor that can pull 300 kg load at the rate of 0.3 m/s.
Instrumented top pulley allows monitoring of down-hole tool position with resolution of 0.2 mm, as
well
as
weight and cable tension with resolution of 0.2 N when the tool is stationary.
Winch drum is equipped with belt brake that can be independently activated with foot pedal or
electric
actuator.
Tilting table allows safe service and effortless operations with the down-hole equipment while it is
on the surface. Tilting table and a pulley are equipped with cable bend limiters that prevent
bending
below the minimum radius.
Launching tube provides antitorque and vertical tool stability during mechanical drilling.
The rig platform leveling mechanisms allow fast setup and adjustments of the mast verticality.

Light
series rig
About
Lightweight drilling rig is designed for operations with "electro-drills" and borehole
logging
devices with power requirements up to 3 kW. It is equipped with 250 m of Kevlar electromechanical
cable.
The
winch is powered with 1.5 kW DC brush motor that can pull a 1000 N load at the speed of 0.8 m/s.
Instrumented top pulley allows monitoring of down-hole tool position with resolution of 0.2 mm, as
well
as
weight, and cable tension of 0.2 N resolution when the tool is stationary.
Winch drum is equipped with a hydraulic foot brake.
Tilting table allows safe service and effortless operations with the down-hole equipment while it is
on
the
surface.
The rig platform leveling mechanisms allow fast setup and adjustment of the mast verticality.
The heaviest parts of the drilling system are winch drum with 250 m cable (22 kg) and motor gearbox
assembly
(23 kg), which is suitable for transportation by porters. Depending on mode of transportation and
degree
of
dismantlement setup takes 1-3 hours.

Light series
electro­mechanical ice core drill
About
Main features of EM-100-1000 electomechanical drill are ability to core temperate ice and transient
submerged operations.
The prototype of submersible motor section for fluid operation has been tested and the drill can be
customized for drilling of fluid-filled boreholes.
The drill is equipped with hammer that ensures stuck drill release.
The electromechanical drill for ultralight ice coring system (from 50 to 75 mm) is currently under
development.

Light series
electro­thermal ice core drill
About
We have designed a new generation of electrothermal drill. The main goals of new development were
reduction of weight, power requirements and drill service time. Reduction of power usage lowers the
penetration rate. However, increased travel speed in fluid-filled borehole and shorter service time
on surface allows for the high production rate of average 2 m/h with power consumption of 1.5 kW in
300 m deep borehole.
The drill can operate in temperate, cold and polythermal glaciers.
