Alliance Scale has released a portable wheel weighing scale for trailers, truck, RVs and motorhomes.

The Alliance/CAS wheel weighing scale is accurate to within 1% of vehicle weight and provides filtering to compensate for vibrations, the company said. Made of rugged cast aluminum with built-in ramps, users can drive each wheel over the scale separately and scales can be linked to weigh an entire multi-axle vehicle at once.

It is available in 10,000 and 20,000 lbs. single- and double-width models and can be run on battery or AC power. Each scale has a 1 in. LCD display to show individual or total weight in pounds or kilograms and can run up to 20 hours on a single charge.
