Assignee: JOY GLOBAL SURFACE MINING INC
Field: Civil engineering (Other fields)
Classification: CPC E | IPC E

Claim 0:
1. A mining shovel comprising:
a base;
a handle rotationally coupled to the base;
a bucket coupled to the handle;
a rope force sensor configured to indicate a rope force on a rope supporting the bucket and the handle;
one or more position sensors configured to indicate a current shovel position; and
a controller including an electronic processor and a memory, the controller coupled to the rope force sensor and to the one or more position sensors, the controller configured to:
receive rope data indicative of the rope force from the rope force sensor,
receive position data indicative of the current shovel position from the one or more position sensors,
determine 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
provide the payload mass to a display device associated with the mining shovel.
