Targeted primarily for refuse, aggregate and logging vehicles, the Mechanical Suspension Onboard Scale from TruckWeight consists of a set of strain gauges or sensors, transmitters and a handheld receiver. The product requires no welding or special tools and can typically be installed in one hour on tractors and trailers with walking beam, leaf-spring and other mechanical suspensions. With a range of 500 ft., the receiver displays axle group and gross vehicle weight readings in three-second intervals, essentially providing real-time truck weights. Furthermore, this upgraded gauge mounts directly to the suspension with a high-strength adhesive. The company notes that gauges will last up to five years and are inexpensive to replace. They also state that the scales accuracy is within 1 percent on level ground. TruckWeight’s air suspension and mechanical suspensions scales are fully compatible to ensure accurate weights with tractor-trailer rigs with both systems. The systems also use the same receiver, and may be integrated with existing telematics systems.
