Study of Forces Acting on Excavator Bucket While Digging

Khedkar Y, Dey T and Padasalagi Y

Excavator is a construction machine which is widely used for various constructions, mining and agricultural work. For easy excavating of tool into soil it’s necessary that the digging force offered by tool must be greater than the resistive force offered by soil. Design of excavator bucket is a challenging work because it’s a first part which comes in contact with soil. Various forces are acting on the bucket which resists the motion of bucket into the soil. This paper focuses on factor affecting the resistive force, also the resistive force offered by stiff soil to the bucket has been designed, and Digging forces are calculated as per SAE standard, Effect of various parameters on resistive force has been discussed for horizontal and uneven digging condition.
