Abstract (en)

A work machine system includes a lower travelling body (21), an upper slewing body (22) slewably attached to an upper portion of the lower travelling body (21), an attachment (30) having a bucket (33) that is capable of holding a work object and is rotatably attached to the upper slewing body (22), and a controller. The controller controls the upper slewing body (22) and the attachment (30) so that the upper slewing body (22) and the attachment (30) perform a series of operations having a plurality of operation phases, detects an amount of the work object held by the bucket (33), sets a target amount that is a target of the amount of the work object, and specifies, as an abnormal phase, an operation phase in which the amount of the work object held by the bucket (33) is smaller than the target amount.
