LTPS log processors (log rip saw)

Woodlandia Log Through Pass Sawmills (LTPS-machines) are intended for processing of small and medium diameter softwood and hardwood raw barked stems into dimensional lumber or custom boards.

These machines can be installed in a shop or in a field under an awning or in a shed. 

LTPS-machines are efficient solution for:

  • businesses needed to saw big amount of small diameter raw stems (pls refer to specification below for max raw stem diameter)
  • businesses specializing in sawing of hardwoods into boards for furniture industry and door/window applications
  • loggers who want to recover lumber from small diameter stems efficiently in a job site
  • businesses utilizing beetle or fire killed stems

Productivity


Productivity of LTPS machine depends on following factors:

  • infrastructure and logistics (in-feed/out-feed automation)
  • wood species
  • boards layout: number of circular saw-blades installed & max height of boards to cut
  • tool sharpness
  • moisture content of the wood

 

 Here are tables describing typical layouts (cutouts) and productivity of LTPS-150E:
