Wulftec LMB-250 Lumber Press

Strapping Machine

The LMB-250 Lumber Press is specifically tailored to the lumber and panel Industries. The hydraulic compression strapping system design facilitates maintenance and operation. Top and side compression ensures stable, tight loads that will retain high tension during transportation. The LMB-250 Lumber Press is easily integrated into existing production lines to create a seamless packaging system.

Wulftec offers the best warranty in the industry:

  • 1-year on the strapping head and track
  • 3-year unlimited cycle warranty
  • 3-years on the steel structure
