StrongWeigh System Components
The Control Box is the heart (or brain) of the Strong Weigh system. One is needed for every truck or tractor, as it communicates with every wireless sensor as well with the operator (via cell phone, tablet, or the StrongWeigh Wireless Display). The Control Box is small (approx. 4.5″ X 3.5″ X 1.25″) and installs near the cab of the truck, typically in the chassis frame. Includes a cable to plug into the truck’s diagnostic port (for power and ECU communication). The Control Box can handle simultaneous communication with more sensors than any truck would possibly need (over 20), and you can easily swap out your trailer and connect the new trailer’s sensors with the press of a button. Plus it includes integrated GPS, accelerometer, and data logging functionality.
Wireless Deflection Sensor
Wireless Air Pressure Sensor
The typical straight truck, like this tandem dump truck in the illustration, requires only three or four components installed to get the StrongWeigh system up and running. Every truck starts with the Strong Weigh Control Box, which you install in the truck frame near the cab of the truck, and connect to the truck’s diagnostic port. Additionally, every truck needs a Strong Weigh Wireless Deflection Sensor on the front steer axle.
As for the rear axle(s) of your straight truck, the type and quantity of sensors depends on the suspension type: Air ride suspensions use the Strong Weigh Wireless Air Pressure Sensor, which easily tees into the air line that supplies the suspension’s air bags. For typical air ride suspensions, all of the air bags share a common air supply line, and thus require only one Wireless Air Pressure Sensor. However, some air ride trucks are configured with each axle having it’s own air supply, usually so that one axle can be lifted when not needed, and in this case one Wireless Air Pressure Sensor is required for each axle.Walking beam suspensions, like the Hendickson Haulmax suspension for example, use two Wireless Deflection Sensors installed on the walking beams – one sensor on the driver side and one on the passenger side. Leaf spring suspensions on drive axles will typically have one Wireless Deflection Sensor installed on the trunnion tube.
The StrongWeigh Onboard Scale System works on virtually any type of tractor-trailer combination. On the tractor, install the StrongWeigh Control Box, a wireless sensor on the front axle, and one or two wireless sensors on the rear tandem axles (depending on the suspension type). Then, for each trailer, install one or two wireless sensors on the trailer’s axles (again, the number and type of sensors depend on the type of suspension on the trailer). If you have one tractor truck with several trailers, or a fleet of tractors and trailers that regularly switch tractor-trailer pairing, StrongWeigh system works wonderfully: When a tractor hitches to a new trailer, there’s no moving any equipment or disconencting and connecting any wires. From the StrongWeigh app on his/her cell phone, tablet, or the StrongWeigh Display mounted inside the cab, the operator simply selects which trailer is currently hitched, and the StrongWeigh system on the tractor immediately pairs up with the sensors on that trailer.
