Commando 300 is a hydraulic, self-propelled drilling
unit on a 4-wheel, oscillated drive carrier. It drills holes
with a maximum recommended diameter of 64 mm (2
1/2") and a maximum practical length of 15 metres
(50'), utilizing 25, 28 or 32 mm (1", 1 1/8" or 1 1/4")
extension rods.
Commando 300 is a completely self contained drilling
unit. It is easily manoeuvrable with good rough terrain
capabilities. It is also easy to transport between job
sites on a truck or on a trailer, or it can even be lifted
by a helicopter.
Commando 300 is equipped with HL 300, hydraulic top
hammer rock drill. The rock drill is mounted on an aluminium
chain feed, which is attached to an articulated
boom giving a drilling coverage of 10 m2 (108 sq-ft). A
48 kW (64 hp) diesel engine supplies power both for
hydraulic pumps and for an on-board compressor.
Several routine functions of Commando 300, e.g. collaring
and antijamming, are automatically executed by
electronic controls.
For easy operation, good visibility and operator safety,
Commando 300 is supplied with an electronic remote
control unit. Thanks to the electronics, this unit has
fewer levers which make it easy to use. For operator
comfort Commando 300 is also equipped with a dust
collection system, which gathers drilling dust from the
hole into a plastic bag.
Typical applications for Commando 300 are foundation
drilling, road cutting, trenching, occasional bolting and
other special drilling applications. Therefore Commando
300 is most often used by construction contractors,
mines and quarries, and the municipal sector.
Due to its versatility Commando 300 is often included
in the equipment fleet of rental houses as well.
