Excavators are used in many ways:
Digging of trenches, holes, foundations
Brush cutting with hydraulic attachments
Mining, especially, but not only open-pit mining
Driving piles, in conjunction with a pile driver
Drilling shafts for footings and rock blasting, by use of an auger or
Hydraulic drill attachment
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 levelling and pushing removed material back into a hole.

- Q:Why do excavators use such complicated drive motors ?
- Actually, the drive system is relatively simple. You have a single engine running a hydraulic pump, and two hydrostatic drive motors on the track system that propel the machine. Beyond that you have two control handles that are tied into the main hydraulic valves with either electronic controls or pilot hydraulics that open and close valves to move the hoe. There are a lot of hoses, but the system itself is really pretty simple in design once you understand it.
- Q:HOW TO BECOME AN ENVIRONMENTAL CONTRACTOR EXCAVATION IN TEXAS?
- Well, to become an environmental excavation first you have to be land. Oh, I think you mean excavator. Then you'd need excavation experience and excavation equipment (backhoes and such). You'd probably need certification of some kind. For government jobs (the most common) you'd probably need to bid on a project, and they take the best bid. Texas government sites should have specific information on this. Knowledge of soil types, environmental habitats, erosion control, etc. would be useful.
