Duluth Ore Dock Upgrades Dock Conveyor with Two 180 HP Rulmeca Motorized Pulleys

Duluth Dock, owned and operated by The Canadian National Railway Company (CN), recently installed two 180 HP Motorized Pulleys at opposite ends of the reversing shuttle belt located atop of the huge ship loader surge bins. They replaced the shuttle's old exposed drives, which were part of the conveyor added to the dock in 1981. With winter temperatures as cold as -20º F, it is essential that the shuttle conveyor drives be reliable and robust in order to keep ore flowing to the dock pockets in the 10,000 tph ship loading system.

Motorized Pulleys at Escanaba Ore Dock Move 200 Million Tons Since 1985

Also owned by CN, the Escanaba Ore Dock Bucket Wheel reclaimer was built in 1965. The two 200 HP Rulmeca Motorized Pulleys, driving the boom and tail conveyors, recently passed the 200 million ton milestone and are now in their 27^th shipping season since they were installed in 1985. Pete Candela, Supervisor of Dock Operations, said, "We are happy with the Rulmeca Motorized Pulleys. They last longer both mechanically and electrically than any other conveyor drive system."

Rulmeca's new Motorized Pulley catalog for North America is now available both in print and online.

Rulmeca will offer "quick ship" local assembly of models 500 and 630 in 2012, with powers available up to 75 HP.

Rulmeca Corporation's website has been upgraded to include "quick catalog look-up" of all models.

Rulmeca and UK Coal will present a paper entitled "Motorized Pulley Usage in UK and US Coal Mining and Power Generation" in Berlin on 9/11/12.
