The hydraulic excavators is a heavy construction machine consisting of a boom or stick, bucket and cab on a rotating platform siting atop an undercarriage with tracks or wheels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors. Excavators are most commonly used to dig trenches, holes and foundations. By using its many attachments it can also be used for material handling, brush and cutting in forestry works, demolition and crushing rocks, steel and concrete structures, laying gravel onto the road prior to paving, general grading and moving landscapes, mining, river dredging and snow removal.

Mini excavators are the versatile from the digging family of heavy machinery. Very small, yet very powerful. May be used in almost all works that require digging, or moving dirt, gravel and rocks in a limited working space. Other equipment may be attached/replace to the front bucket, making it even more versatile.

Excavators used in mining operations can be up to five stories high. Minor landscape jobs can be worked using a rubber track mini-excavator that stands little more than seven-feet high. Deciding what size of excavator to rent for a job depends on two factors: how much material you need to move and how much reach you need with the boom and arm.
Rubber-track mini-excavators are available with buckets that are no larger than a 5-gallon bucket and a boom and arm with only ten-feet of reach. Larger excavators, those that are still small enough to be transported on a low-boy trailer, can have up to 30 feet of reach and hold almost a yard of material.
Excavators are used to dig trench, remove material, place material, and landscape on a large scale. Excavators are also extremely adept at demolition and there are a variety of rental implements that an operator can attach to the arm of a track hoe besides a bucket. Excavators are commonly used in tandem with dump trucks, end dumps and side dumps. Track hoes are practical rental machines for the following types of jobs:
