Tracked Self-Driven Dozer Mining Unit (TDMU)
OVERVIEW
Being continuously tethered at up to a 500m working radius provides the flexibility to continuously recover large blocks or narrow tracts of resource, with quick change-over times to start up the next block / section. And they can climb up to 30 degree slopes, to simplify pit transitions. Powered by incoming HV via cable reel, on-board genset, or piggy-backed mobile genset for travel off-grid. All controlled from a fully insulated switch room built to cool-room spec with a marine grade air-conditioner for maximum reliability in hot climates.
Stockpile Reclaim Dozer Trap
OVERVIEW
Modular skid mounted dozer trap module constructed to modern OHS, operational and maintenance standards, for loading yard conveyors from 2.5m RL. Very robust construction, grizzly protected, with easy access for cleaning, and simplified maintenance requirements. Adjustable bed depth to handle ore variation, automated hydraulic belt tensioning / take-up system, modular bolted UHMWPE chute panels for long life and low wall friction, optionally with ceramic button linings to suit highly abrasive ores, complete with crowned pulleys, s/s primary, secondary and return scrapers, and belt splicing station, make these units very easy to live with. Using fabric belts to suit ores such as bauxite, salt and sand, but well suited to use with iron ore and most heavy / lumpy / rock ores, using a steel cord belt on the conservatively sized pulleys.
The modular structure is fully hot dip galvanised and stainless steel / non-corrosive materials used for all belt contacting components. Configured with a robust headwall for dozer pushing forces,
and an integral rilling-style side wing-wall, these units can easily be transported to site as ‘flat-packs’, containerised, or sent fully complete, tested and ready for operation. Quick-remove FEL hopper option available.Available configured to be fixed to foundations, or fully portable via dozer push points / tow points and rounded infills to minimise pushing / towing forces. When used in combination with tracked portable radial stackers, they make for a very efficient stockpile configuration for rapid ship-loading and flexible storage systems.
