2.4.2 Power pack
The hydraulic drill rig is powered by a turbocharged, water-cooled diesel engine which is
equipped with an afterburner chamber to reduce emissions.
The diesel engine is equipped with a monitoring system that includes automatic shut-down
functions.
The drill rig is driven by two traction motors with gears. The traction motors with gears are
mounted in the track frames.
The hydraulic pumps and the compressor are driven by a diesel engine.
2.4.3 Exhaust filtering (Tier 4 Final)
Regeneration is a process that burns the soot from the diesel engine's particle filter, which
cleans the exhaust emissions. In most cases regeneration is started completely automatic-
ally and without affecting the rig's performance. Regeneration can be run in two different
modes depending on the speed of the diesel engine and calculated soot level in the
particle filter.
In addition to the particulate filter, this rig is equipped with a system that injects DEF
(Diesel Exhaust Fluid) into the machine's exhaust system. By means of a chemical reac-
tion, this fluid dramatically reduces the amount of harmful nitrogen oxides (NOx gases) the
rig releases into the atmosphere.
2.4.4 Boom system
The boom system consists of inner/outer boom bodies, boom head, feed holder and asso-
ciated hydraulic cylinders. The boom system is controlled by directional valves for position-
ing the feed with the rock drill at different distances and directions.
2.4.5 Dust collector
The hydraulically driven dust collector features automatic cleaning and consists of a filter
unit, pre-separator, suction fan and suction hose.
2.4.6 Electrical system
The 24 V electrical system is supplied with current by an alternator and two batteries.
The electrical system comprises starting equipment, work lights, electric controls and
safety devices.
