For inspiration to Feed the Beast! in 2026, the mandate is clear to automate, however, the path to automation looks different depending on your starting point. Let’s compare two standout 2025 LimTek installations—a greenfield plant and a modernizing retrofit—to see how Enventek’s Lumber PickLine and amazing RetroC systems redefine production and increase operating profits.

LimTek Process Organization Technology will help you deliver quality trusses with shorter lead times to better service your customers and maximize your investment in automation. A greenfield truss plant is a rare opportunity to implement processes as designed within start-up constraints without the push-back of change by existing plant personnel. It is a breeze to teach and train new people to follow our process organization technology as laid out in a brand new plant. [For all photos, See PDF or View in Full Issue.]

Choosing the fully loaded RetroC for a new greenfield facility ensures a seamless start-up with built-in efficiency. This in-line production system doesn’t just save on labor; it fundamentally redefines the plant’s cost structure, providing a long-term strategic edge especially when entering a competitive market.

While a greenfield installation is technically more straightforward, it introduces the unique pressure of orchestrating multiple trades and building elements simultaneously. Furthermore, a lack of established onsite services is a common hurdle—but it is one that an experienced crew is well-equipped to manage.

Modernizing an active plant requires a “surgical” approach to safeguard daily production. For this 2025 project, we executed a successful two-stage strategy to keep the lumber moving:

Phase 1: The PickLine and RetroC were installed and made fully operational. To keep the existing Monet DeRobo linear saw running, we pivoted to side-loading via forklift, as the new PickLine trough obstructed traditional end-feeding.

Phase 2: We completed the Double PickLine trough and integrated SmartConveyors. This fully automated the feeding process for the DeRobo.

This phased rollout allowed the plant to more than double its cutting output with excess capacity to support additional truss tables in the future.

Whether building a greenfield plant or retrofitting an existing plant, the Enventek PickLine is designed for maximum ROI flexibility. While new facilities may choose to install the PickLine on fresh concrete if the budget allows, existing plants can gain an immediate advantage by utilizing their established driveways and forklift paths. This eliminates unnecessary costs and prevents production delays.

By separating picking lumber from dense lumber storage, both plant types can leverage existing forklift paths for a faster return on investment. The PickLine’s robust automation optimizes yard space, slashes forklift operating costs, and reduces equipment wear and tear. Pick lumber more efficiently to drive truss-building productivity—a benefit that scales rapidly when feeding multiple saws from the same bunks of lumber.
