Abstract
A work machine includes an attachment rotatably attached to an upper turning body; a gripping part rotatably attached to the attachment, the gripping part gripping a long carried-material; and processing circuitry, and a memory storing computer-readable instructions, which when executed, cause the processing circuitry to calculate a weight of the carried-material, based on a torque for rotating the attachment.
Claims20
A work machine comprising:
- an attachment rotatably attached to an upper turning body, the attachment being rotatable about a first rotation axis oriented in a vehicle width direction of the upper turning body;
- a gripping part rotatably attached to the attachment, the gripping part being rotatable about a second rotation axis in a plane to which the first rotation axis is normal, the gripping part being configured to grip a long carried-material;
- and
- processing circuitry, configured to calculate a weight of the long carried-material at a predetermined rotational position of the gripping part where a longitudinal direction of the long carried-material gripped by the gripping part is at a right angle to a front direction of the upper turning body, based on a torque for rotating the attachment.
A work machine comprising:
- an attachment rotatably attached to an upper turning body;
- a gripping part rotatably attached to the attachment, the gripping part being configured to grip a long carried-material;
- an imaging device configured to capture an image of the long carried-material gripped by the gripping part;
- and
- processing circuitry configured to
- estimate a center of gravity position of the long carried-material based on the image of the long carried-material captured by the imaging device, and
- calculate a weight of the long carried-material based on the estimated center of gravity position and a thrust for rotating the attachment.
A work machine support system for a work machine, the work machine including an attachment rotatably attached to an upper turning body, the attachment being rotatable about a first rotation axis oriented in a vehicle width direction of the upper turning body, and a gripping part rotatably attached to the attachment, the gripping part being rotatable about a second rotation axis in a plane to which the first rotation axis is normal, the gripping part being configured to grip a long carried-material, the work machine support system comprising:
- processing circuitry configured to calculate a weight of the long carried-material at a predetermined rotational position of the gripping part where a longitudinal direction of the long carried-material gripped by the gripping part is at a right angle to a front direction of the upper turning body, based on a torque for rotating the attachment of the work machine,
- wherein the processing circuitry is configured to calculate the weight of the long carried-material while the long carried-material is gripped by the gripping part of the work machine.
