The drive gears run in an oil bath lube, while the vibrator shaft bearings utilize a grease lube. In the event of a bearing failure, this prevents contamination of all 4 bearings, unlike mechanisms using flow through oil lube systems. Pioneer's Variable Speed Drive option allows the operator to vary the rate of feed to the crusher and obtain optimum crusher performance. The drive mechanism is mounted directly to the feeder and is hydraulically driven. Pioneer Hoppers are fabricated of extra heavy-duty plate steel and include support structures for additional hopper extensions.
Pioneer offers support frame structures for assisting customers completing their own installations.
