As technology evolves, infrastructure technology is also an important part of the country's economic growth. Since 1925, “C” excavator has been assisting producers worldwide by making progress that drives positive change. Excavators are heavy equipment and are usually used for excavations. The commonly used operation Excavator, all coordinated from the arm; boom cylinder and buckets. In this study discussing the excavator stress analysis of excavator bucket link to determine the safety factor, the excavator bucket link is a “C” 390F link bucket. The stress analysis process on excavator link buckets uses manual calculations. The method that involves determining the material type IS 2062 steel plate. A static linear calculation analysis using element method up to see the maximum stress occurring in the 5-point excavator link bucket style, acquired vonMises voltage value of 52.11 MPa. Maximum breakout force at the angle of 30 ° position style.
