Abstract
Official abstract text for this publication.
A work machine includes: a work state detection unit detecting a physical amount; a time integration unit calculating a time integration value; a determination unit associating the time integration value with a predetermined operating angle of an excavation-loading mechanism and determining that an operation of an operation lever is performed at a time the time integration value is not smaller than a predetermined integration value; a counting unit performing accumulation adding with number of times of loading as once at a time each operation is an excavation-loading work performed in an order of: an excavation operation; a forward swing operation; a soil discharge operation; and a backward swing operation; a default setting unit setting a bucket capacity; a workload calculation unit calculating a workload by multiplying the number of times of loading by the bucket capacity; and an output unit outputting the workload.
First claim
Opening claim text (preview).
The invention claimed is: 1. A work machine comprising: a work state detection unit configured to detect a physical amount output in response to an operation of an operation lever; a time integration unit configured to calculate a time integration value by performing time-integration of the physical amount; a determination unit configured to associate the time integration value with a predetermined operating angle of an excavation-loading mechanism, the operation angle being a…
