Roller Breaker / Excavator

What is Excavator?

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

Excavators can be used in many ways like:

  • Digging of trenches, holes, foundations
  • Material handling
  • Brush cutting with hydraulic attachments
  • Forestry work
  • Forestry mulching
  • Demolition
  • General grading/landscaping
  • Mining, especially, but not only open-pit mining
  • River dredging
  • Driving piles, in conjunction with a pile driver
  • Drilling shafts for footings and rock blasting, by use of an auger or hydraulic drill attachment
  • Snow removal with snowplow and snow blower attachments
