Publication number: 20240044110Abstract: A work machine includes: a load acquisition section which acquires a load of an object held by an attachment; and an estimative load determination part which determines, based on the load acquired by the load acquisition section, an estimative load of the object estimated to be discharged at a position above a destination in a discharge task when a predetermined estimative load determinative criterion is satisfied. The estimative load determinative criterion includes at least one of a criterion that a boom rising speed at which a boom rises in a rising direction reduces in a holding task, and a criterion that the boom rising speed reduces in a carrying task.Type: ApplicationFiled: September 2, 2020Publication date: February 8, 2024Applicant: KOBELCO CONSTRUCTION MACHINERY CO., LTD.Inventors: Toshiro UETA, Michio HIRAYAMA, Kazuomi ENDO

Publication number: 20220389681Abstract: In a work machine, a load information output part outputs a load calculated by a load calculation part as load information before a piston member shifting toward a stroke end reaches a specific position, and a load storage part stores the load calculated by the load calculation part as a specific load when the piston member shifting toward the stroke end reaches the specific position. The load information output part further outputs the specific load as the load information after the piston member shifting toward the stroke end enters a specific region.Type: ApplicationFiled: September 2, 2020Publication date: December 8, 2022Applicant: KOBELCO CONSTRUCTION MACHINERY CO., LTD.Inventors: Toshiro UETA, Michio HIRAYAMA, Kazuomi ENDO
