Excavators (hydraulic excavators) are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the "house". The house sits atop an undercarriage with tracks or wheels. 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 and hydraulic motors. Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators which uses winches and steel ropes to accomplish the movements.

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:
