An excavator boom is a component used to operate an excavator, a piece of heavy machinery used for digging holes or otherwise moving large amounts of material. The excavator usually consists of a base with tracks or treads attached to rotating wheels, as well as a unit known as the house that rotates 360 degrees so the operator can access
