Making Log Troughs Easier to Maintain and Assemble

Share Post:

Last week we looked at the standard designs for log decks. When researching them, we also looked at log troughs and likewise weren’t satisfied with the designs we found. So, we spent extra time on the front end designing a product that really works and meets the real-life demands of sawmills and other lumber-processing plants. The result was a more accurate and reliable design that was easier to assemble and easier to maintain than trough designs already on the market.

Here are some of our improvements:

Laser-Cut Parts

We decided to use this manufacturing method for maximum accuracy and consistency. Whenever possible, we design in alignment and locking tabs to minimize variation in the weldments.

Notice the tabs.

In this assembly, we designed the chain guides to lock into the floor plates. During assembly, technicians dropped the guides into the slots, drove them home with a hammer, and tack-welded at one end. When it comes time for them to replace the guides, they’ll simply grind the small weld away, drive them back to release, install new guides, and drive them home again.

The clean result can be seen on the right.

Floors and Wear Parts are Bolt In Place

We considered little details like using through bolts rather than tapped holes when designing our log trough. Bolts in tapped holes rust in place, whereas bolts with nuts allow technicians to cut off the nut and replace the bolt easily.

Shipped With Assembly in Mind

The installation will be a snap because the splice plates are laser cut, and the assembly is jig welded.
