The controller includes a weight calculating part configured to measure a weight of a transporting object to be transported by the work tool, based on a boom cylinder pressure of the boom cylinder, and a vibration control part configured to generate a command for reducing vibration of the attachment.
Claims9
A work machine comprising:
- a lower structure;
- a slewing upper structure slewably attached to the lower structure;
- an attachment, including at least a boom, and attached to the slewing upper structure;
- a boom cylinder configured to drive the boom;
- a lifting magnet attached to the attachment;
- a power controller configured to control a supply voltage that is supplied to the lifting magnet to excite the lifting magnet;
- and
- a controller,
- wherein the controller includes:
- a storage device configured to store a program, and
- a processor configured to execute the program to perform a process including:
- calculating a weight of a transporting object to be transported by the lifting magnet, based on a boom cylinder pressure of the boom cylinder, and
- generating a command for reducing vibration of the attachment,
- wherein the generating generates a command to the power controller for controlling the supply voltage supplied to the lifting magnet.
