Abstract— Excavators are intended for excavating rocks and soils. It consists of four link members: the bucket, the stick, the boom and the revolving super structure (upper carriage). The excavator mechanism must work reliably under unpredictable working conditions. Thus it is very much necessary for the designers to provide not only a equipment of maximum reliability but also of minimum weight and cost, keeping design safe under all loading conditions. The two important factors considered during designing an excavator arm are productivity and fuel consumption. Also the bucket volume is increased to compensate for the loss in production due to the reduction in digging force. Increased in bucket volume will also increase the amount material to be fed in the bucket. The present paper is review of various analysis done on components of excavator arm and there are various forces affects on components of excavator arm. This paper will be helpful for those who are working in the field of civil engineering.
