Get a Custom Quote Today!

 Designed for trailers, dollys fitted with air bag suspension with single ride or dual height control valves and requires the AXM as a master system gauge.

Made of polycarbonate, a high impact material, the AXL400 guarantees durability and weather resistance. With its bright LED screen the display is clearly visible to operators outside the truck; day or night. It also has alarm features to let your know when the vehicle has reached a specific weight.

The AXL400 is a Wifi-enabled version of our AXM truck scales. It’s an intermediate version between the AXL300 series and AXM series. It collects the weights only from the trailers whilst requires an AXM truck scale to work as a master system gauge on the truck.

Allows you to check your weights from your smartphone and save them for later reference, or from inside the cab using the AXM Remote Display (optional).
