1. An excavator, comprising:
an undercarriage;
a rotating platform rotatably provided on the undercarriage;
an attachment being attached to the rotating platform;
a turning hydraulic motor for driving the rotating platform;
an actuator for driving the attachment; and
a sensor for detecting motion of the excavator, wherein the sensor is adaptive to detect the slip of the undercarriage when the actuator operates; and
a slip suppression unit for, based on output from the sensor, suppressing the slip of the undercarriage.
|
5. A method of controlling an excavator having an actuator for driving an attachment and a turning hydraulic motor, the method comprising:
a sensor detecting the slip of an undercarriage when the actuator operates; and
a step of suppressing the slip of the undercarriage based on an output from the sensor.
|
6. An excavator, comprising:
an undercarriage;
a rotating platform rotatably provided on the undercarriage;
an attachment attached to the rotating platform;
a turning hydraulic motor for driving the rotating platform;
an actuator for driving the attachment; and
a sensor for detecting motion of the excavator during excavation work performed by the actuator driving the attachment; and
a control device configured to detect a displacement of the undercarriage during the excavation work performed by the actuator driving the attachment based on an output of the sensor and to suppress slip of the undercarriage.
