Claim 10:
11. A method of determining a payload mass for a mining shovel, the method comprising:
receiving, at an electronic processor, rope data from a rope force sensor indicative of a rope force on a rope supporting a bucket and a handle of the mining shovel,
receiving, at the electronic processor, position data from one or more position sensors indicative of a current shovel position of the mining shovel,
determining a payload mass based on the rope force, the current shovel position, and a defined relationship between a kinetic energy of the mining shovel, a potential energy of the mining shovel, one or more degrees of freedom of the mining shovel, and one or more forces experienced by the mining shovel, and
providing the payload mass to a display device associated with the mining shovel.
