Abstract
A work machine includes: a work machine body; an attachment attached to the work machine body; a work tool provided at a distal end of the attachment; and control circuitry. The control circuitry is configured to, when a determination is made that a piston of a cylinder that operates the attachment has reached a predetermined range based on detection information related to a raising operation of the attachment after an object is held in the work tool, cause an obtaining measurement result of a weight of the object to differ according to a state of the work machine at a time when the determination is made.
Claims8
A work machine, comprising:
- a work machine body;
- an attachment attached to the work machine body;
- a work tool provided at a distal end of the attachment;
- and
- control circuitry configured to, when a determination is made that a piston of a cylinder that operates the attachment has reached a predetermined range based on detection information related to a raising operation of the attachment after an object is held in the work tool, cause an obtaining measurement result of a weight of the object to differ according to a state of the work machine at a time when the determination is made.
A work machine, comprising:
- a work machine body;
- an attachment attached to the work machine body;
- a work tool provided at a distal end of the attachment;
- and
- control circuitry configured to, when a determination is made that a piston of a cylinder that operates the attachment has reached a predetermined range based on detection information related to a raising operation of the attachment after an object is held in the work tool, cause an obtaining measurement result of a weight of the object to differ according to a state of the work machine at a time when the determination is made, wherein
- the control circuitry
- obtains the weight of the object calculated based on the detection information related to the raising operation of the attachment as the measurement result at the time the determination is made, when the state of the work machine at the time the determination is made is a state after the raising operation of the attachment has started and the measurement result of the weight of the object has not been obtained,
- obtains the measurement result that has been obtained as the measurement result of the weight of the object at the time the determination is made when the state of the work machine at the time the determination is made is a state after the raising operation of the attachment has started and the measurement result of the weight of the object has been obtained, and
- does not obtain the measurement result when the state of the work machine at the time the determination is made is a state at start of the raising operation of the attachment.
A control apparatus for a work machine, comprising:
- a work machine body;
- an attachment attached to the work machine body;
- and
- a work tool provided at a distal end of the attachment, wherein
- the control apparatus includes
- control circuitry configured to, when a determination is made that a piston of a cylinder that operates the attachment has reached a predetermined range based on detection information related to a raising operation of the attachment after an object is held in the work tool, cause an obtaining measurement result of a weight of the object to differ according to a state of the work machine at a time when the determination is made.
