METHOD AND APPARATUS FOR CALCULATING PAYLOAD WEIGHT

摘要

An apparatus for determining the weight of a payload (44) in a bucket (24) of a machine (20) where the bucket (24) is attached to a chassis (26) of the machine (20) by a linkage. The apparatus comprises an energy storage device (82) for storing potential energy of the bucket (24), payload (44), and linkage when the bucket (24) is moved from a first suspended position to a second suspended position. A mechanism (86) provides physical data corresponding to a physical change in the energy storage device (82) caused by storage of the potential energy and a processor (116) calculates the weight of the payload (44) using the physical data.
