We have not found a walk-up public scale house in Multnomah, Clackamas, Washington or Marion County with an operator page we can cite, and ScaleRegistry’s public-weighing page lists none in Oregon. We are not inventing one from industrial scale vendors, gravel yards, recyclers, transfer-station gate scales, or third-party trucker directories. All three stops below are CAT Scales at truck stops, verified on TA Petro’s and Love’s own location pages.
CAT Scales in Troutdale and Aurora
We list only stops verified on the operator’s own location page. TA Troutdale and TA Aurora list CAT Scale on TA Petro’s own pages and show the location as Open 24 Hours; Love’s #449 lists CAT Scales in its amenities and lists the store as Open 24-hours. Those are store hours, not a published CAT-staffing schedule. If one Troutdale scale is busy, the other is at the same exit. 2,000 lb floor. No corner weights. Weigh the whole rig, then drop the trailer and weigh the tow vehicle for the trailer number. Do not unload horses at a truck stop. Oregon weighmaster rules differ from California — confirm ticket needs with your TO or licensing office. Use CAT’s locator for other stops.
