Gearless Drives for Overland Conveyors

Responding to the mining industry’s needs for larger, more efficient conveyor drives, ThyssenKrupp Robins is supplying the first modern gearless drives for conveyor systems.

Deeper mines, decreasing ore grades, and increasing material handling needs are requiring larger, longer, and more powerful conveying systems.

ThyssenKrupp Robins, in partnership with Siemens has developed and is building a Gearless Drive overland conveying system using cycloconverter-fed 3,800 kW synchronous motor drives.

The most recent installation at Xstrata's Antapaccay mine in Peru features 2 x 3,800 kW Siemens Gearless Drives and is in operation since Nov. 2012. 

An additional order for 4 x 4,400 kW gearless drive conveyor systems for the Las Babas mine was received earlier in 2012. 

Antapaccay Gearless Drives

The first gearless drive was designed and built over 25 years ago by what is now ThyssenKrupp at the Prosper-Haniel coal mine in Germany.  It is still operating successfully with very high availabilities at this mine. 

Prosper Haniel

Applying current proven gearless drive and cycloconverter technology allows conveyor drives of 3,000 kW and larger to be used.

ThyssenKrupp Gearless Conveyor Drive solutions provide many benefits including increased plant availability, increased energy efficiency, reduced maintenance costs, reduced spare parts inventory, and reduced footprint requirements.
