Bucyrus VFD controls improve performance of room & pillar mining equipment

international-mining-logoAdding a variable frequency drive (VFD) to a compatible Bucyrus machine has a positive impact on the bottom line. Costly DC motors are replaced by more efficient brushless AC motors which require less maintenance and have a longer service life. A Un-A-Hauler® with VFD control transports more tonnes per shift. A VFD-equipped Vers-A-Trac® completes longwall moves faster. Feeder breakers with VFD allow hauler operators to unload faster without fear of costly downtime. And in continuous miners, VFD traction control improves non-productive move times as well as sump and cut performance. (more…)
