TruckWeight touts wireless scale for mechanical suspensions

TruckWeight says its Smart Scale wireless onboard scale now is available for trucks, tractors and trailers with mechanical spring suspensions, such as vehicles used in bulk distribution, agriculture, construction, forestry, containerized loads and heavy hauling.

Smart Scale for mechanical suspensions includes three components: an axle-mounted load sensor, a low-powered radio transmitter and a small handheld wireless receiver. The load sensor measures subtle changes in the deflection of the axle; it feeds this data to the transmitter, which relays it to the handheld receiver up to 500 feet (155 meters) away. The result is a weight calculation that’s accurate to within 1 percent compared to a certified scale, according to the company, which touts several benefits of the unit:

  • Smart Scale uses AA batteries for power and does not require electricity from a truck or tractor. For the first time, users can actively manage the weight of an untethered trailer as it is being loaded. Fleet managers can deploy their power units where they need them and eliminate the time and inconvenience of hooking up a tractor in order to use a scale;
  • One handheld receiver can monitor both mechanical spring and air-ride sensors on the same vehicle or combination. This ability to distinguish unique vehicles is suitable for fleets that interchange equipment with air-ride and mechanical spring suspensions;
  • The axle-load sensor can be used on a range of commercial equipment, including severe-duty trailers and railcars; and
  • The low-powered RF signal is intrinsically safe, and the wireless feature is useful for drivers who load their own vehicle and want to verify and fine-tune distribution of the payload.
