WEIGHT MEASUREMENT SYSTEM FOR ACCURATELY DETERMINING THE WEIGHT OF MATERIAL IN A CONTAINER BEING LIFTED
First Claim
1. A weight measurement system for accurately determining the weight of a material in a container being lifted, the system comprising:
- a hydraulic system comprising a mechanical lift arm for lifting and emptying a container;
a dampener operable on the hydraulic system for reducing and minimising oscillations of the hydraulic system during operation of the mechanical arm;
a weight transducer based weighing system for weighing the container during at least one of a lift and after being emptied and to provide an output indicative of each weighing during periods of dampening of the mechanical lift arm,a processor configured to use at least the outputs of the weighing system to provide a weight of the material in the container.
