Excavators are heavy equipment consisting of a boom, bucket and cab on a rotating platform (known as the “house”). The house sits atop an undercarriage with tracks or wheels. All movement and functions of the excavator are accomplished through the use of hydraulic fluid, be it with rams or motors. Their design is a natural progression from the steam shovel.

Excavators Are Used In Many Ways:

  1. Digging of trenches, holes, foundations
  2. Material handling
  3. Brush cutting with hydraulic attachments
  4. Forestry work
  5. Demolition
  6. General grading/landscaping
  7. Heavy lift, e.g. lifting and placing of pipes
  8. Mining, especially, but not only open-pit mining
  9. River dredging
  10. Driving piles, in conjunction with a Pile Driver

In recent years, hydraulic excavator capabilities have expanded far beyond excavation tasks with buckets. With the advent of hydraulic powered attachments such as a breaker, a grapple or an auger, the excavator is frequently used in many applications other than excavation. Many excavators feature a quick coupler for simplified attachment mounting, increasing the machine’s utilization on the jobsite. excavators are usually employed together with loaders and bulldozers. Most wheeled, compact and some medium sized (11 to 18 tonne) excavators have a backfill (or dozer) blade. This is a horizontal bulldozer-like blade attached to the undercarriage and is used for leveling & pushing removed material back into a hole.
