METHOD OF CONTROLLING A QUICK COUPLER OF AN EXCAVATOR AND APPARATUS FOR PERFORMING THE SAME

摘要

According to a method to control a quick coupler of an excavator, a warning sound rings in an unlock mode of a quick clamp switch wherein an attachment is separated from a quick coupler. A warning sound rings from a release mode of the quick clamp switch to a neutral mode. When the neutral mode of the quick clamp switch is shifted to a lock mode, the warning noise is stopped. As such, the warning sound rings during the neutral mode, and a worker can accurately recognize that the quick coupler stably locks the attachment; thus preventing accidents where lives are lost.
