Primary Log Breakdown

Vertical Quad Roll Log Turner

The vertical roll log turner utilizes two sets of two pivoting vertical rolls that move vertically in opposite directions to effectively turn a log irrespective of its form or defects. It normally is controlled by the optimizer program based on scanner data but may also be manually operated. It provides an essential first operation for maximum lumber recovery.
