2004 Niemac Trophy

Roddy Maxwell of Fulton Hogan’s Parkburn Quarry took out the honours this year for an innovative approach to solving a new project at the quarry

Roddy has been employed by Fulton Hogan for 38 years orginally in Dunedin then based up in Alexandra. Roddy spent a lot of time with the construction arm of FH then moved into the quarrying business. FH Central predominently extract and crush gravel from both pits and rivers.

Parkburn Quarry covers 76 hectares, is located in the Cromwell area has 100 year life expectancy with approx 10 million cubic metres available.

Innovation was in the form of large field conveyors replacing the use of haulers to bring alluvial greywacke gravels to the plant, with the design allowing for future chip plant to be linked in.

Components in the system are:

  • Ground conveyor – approx 120 m in length
  • Stacker conveyor – 35m long, 18 degrees, 1500m3 surge pile capacity
  • Tunnel feeder
  • 3 deck screen – 4.8m x 1.4m
  • Link conveyor to
  • Secondary screen for gravel and sand
  • Trident II dewaterer
  • Control room

Impact on the environment was lessened by reducing dust generation and the use of fossil fuels. It also reduces the people factor to find good operators to drive haul trucks. td>
