The powerpack maximizes mechanical efficiency

and isolates the components from drilling and propelling shock loads. High pressure compressors for efficient DTH drilling

Tower pinning is performed remotely

from within the operator's cab

The cab design allows a direct line of sight

from the operator's seat to the drill table
