摘要： The present invention relates to an excavator arm having a rotation device. The excavator arm is connected to a boom of an excavator to be operated by a cylinder, connected with a bucket for excavation at the lower end through a quick coupler, and connected with a bucket cylinder for operating the bucket over the arm. The arm is divided into an upper arm and a lower arm and a rotation device that selectively rotates the lower arm at predetermined angles over 360° in both directions is fixed between the upper arm and the lower arm.
