What product is right for my business?

For those who have a LoadMaxx tractor scale, adding the LoadMaxx Plus with Communication to your trailer turns your vehicle into a complete self-weighing vehicle and is perfect for fleets that drop and hook. By multiplexing through the existing 7-way, both tractor and trailer weights are seen on the in-cab display without any driver interaction.

Our QuickLoad Plus standalone trailer scale is right for you if you simply need to know your trailer’s weights while you’re loading. QuickLoad Plus is a simple plug-n-play solution that offers an optional communication to the Air-Weigh App.

The all-new QuickWeigh is the go-to solution for equipment utilization. An economical, all in one retail package is designed for air-ride suspensions, for use with the new QuickWeigh app available on most smart devices. QuickWeigh brings all the accuracy and dependability you know from other Air-Weigh on-board scales at an all new economical price offering.

Western Distributing

Air-Weigh scales help our fleet to realize our weight issues at the dock – not 60 miles out of route, down the road, after the shipper has closed. This ensures that we maintain our on-time delivery to the customer and reduces out-of-route costs to scales. Better to be proactive than reactive!

We use Air-Weigh scales to ensure that we pick up a full load every time. In fact, the first big haul after we installed them paid for the scales! I also like the peace of mind of knowing we won’t get an overweight ticket.
