ELECTRIC TRACTION DRIVES

Performance Advantages DC cable more reliable
Can get more cable on the reel
Load Sharing Tram Motors DC cable quicker/easier to troubleshoot and repair
Smooth and Reliable Electrical Braking Longer lengths allowed by MSHA – 850 feet of #2/0 is common
Variable Speed / Reversible Conveyor Control Less Trailing Cable heat - up to 75 percent less heat than 250VDC Trailing Cables
Approximately two times more power can be delivered to the
Trailing Cable Advantages
Shuttle Car via the 550VDC Cable
