We specialize in log handling and canter line machinery, and have experience in every aspect of the sawmill environment. Over the years we have developed ground-breaking innovations in in-feed hold downs; compact, high speed log turners; the toughest log singulators and more. All of our solutions are designed to ensure ease of maintenance, product quality and efficiency.

Industry leading solutions

When speed and efficiency matter most.

All of our solutions are designed to ensure ease of maintenance, product quality and efficiency. For example:
  • Our pneumatic tire holds down rolls securing the log firmly without damaging any fiber. In addition, the lightweight rolls allow you to use less air pressure during the lift cycle.
  • Our quad spiked rolls carry the log with greater stability across your bottom head, giving you more ‘traction control’ for steady feeding, as well as improved hold back power.
  • Our replaceable threaded spikes that are considered the best in the industry
  • Our heavy duty telescoping drive shaft powers spiked rolls with the motor and reducer ‘fixed’ to the overhead frame out of harm’s way — it’s the fastest log turner anywhere.
