Technical features

• Loading from car to car, inside conveyors provide quicker loading than any other system currently on the market.
• By matching size and number of Shuttlecars to the volume of blasted rock the whole round can be removed in one trip.
• Conveyors use heavy-duty chains with long life 'flights' to carry the muck.
• Dual electric motors power the conveyors via centrifugal clutches and worm gears.
• Elimination of unnecessary stopping out of niches and alcoves.
• The cars can be coupled to each other, up to eight cars together allowing 100 m³ of muck to be transported in one trip.
• Spotlights are mounted on each Shuttlecar to provide a well-lit and safe environment.
• The chains on the conveyor are heavy-duty with long life 'flights' to carry the muck.
• The floor of the shuttlecar is lined with Hardox 500 wear plates, providing long life and low service requirements.
• Dual electric motors power the conveyors via centrifugal clutches and worm gears.

• Remote control allows up to three shuttlecars to be operated by the same operator.
• The chassis are made of heavy-duty plate joint with continuous welds for max fatigue strength.
• The shuttlecars have specially designed boogies, with centre suspension and rubber springs that contributes to a smooth and safe running of each car.
• Minimized risk of derailing, even when running on uneven tracks.
• The centre suspension features a well-protected Teflon bearing that requires virtually no maintenance.
• The boogie can swing 45° on either side.
• Reduced wear of wheel flanges and maintained speed of haulage even with heavy transports.
• The wheel and flange are flame-hardened to a minimum of 320 HB.
• The standard bar for linking the locomotive and shuttlecars together is a straight draw bar which can take most couplings.
• HRST Shuttlecars used with Gialoader form a complete unit for our well-known 'High Speed Tunnelling Method'.
