Vehicle axle load weighing system
First Claim
1. A method for determining the axle weights of a vehicle of the type having a first and second longitudinally spaced apart axle assemblies, a frame, and a load bed, the reel comprising:
- (a) providing a plurality of weight sensors for supplying signals, wherein at least one weight sensor is longitudinally spaced apart from the axle assemblies, each signal being representative of a weight exerted at the location of the sensor;
(b) processing the signals supplied by said weight sensors to determine the weight exerted on the first axle assembly, based upon an equilibrium of moments about the first axle assembly, at the weight sensors and the second axle system.

Abstract
A system for determining the load on each axle of a vehicle (150) uses load cells (130, 140) mounted on the bed of the vehicle (150) at load-bearing locations that are longitudinally spaced apart from the axles. Axle weight for each axle is determined from the load cell output signals based upon the moments about the effective longitudinal center point of each axle assembly, and the load-bearing points at which the load cells are mounted. System calibration is effected by using load cell signals when the vehicle (150) is unloaded and load cell signals when the vehicle (150) is loaded.
