EXCAVATOR
Excavators are heavy construction equipment consisting of a boom, bucket & cab on a rotating platform known known as the "house"The house sits atop an undercarriage with tracks or wheel They are a natural progression from the steam shovels and often mistakenly called power shovels.All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid with hydraulic cylinders & hydraulic motors.Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators which use winches and steel ropes to accomplish the movements.
