more robust mechanical connections in the wiring
harnesses.

The Cubex ERIS system is set up so that mine managers
and engineers are able access the benefits of an
expandable control platform. This unit has proven
to be very reliable, while providing a high degree of
productivity.
Performance: The LH1 can be used to drill from 1 5/8 in.
(41 mm) to 4 in. (102 mm) diameter holes to a depth
greater than 60 ft. (20 m). The range of drilling includes
360° ring in 107° of plane from 3° below horizontal to
15° past vertical.
Optional Accra Feed and ERIS panel
The inclusion of Accra Feed on Cubex underground
drills has increased overall drill performance by
providing optimal pressure to the bit in all rock
conditions. Lost drill string situations are reduced and
overall hole integrity is improved.
