Excavators are heavy construction equipment consisting of a boom, dipper, bucket and cab on a rotating platform known as the "house". Excavators are also called diggers, JCBs, mechanical shovels, or 360-degree excavators. Excavators are usually specified by their dig depth, arm force, dump height, maximum height, and power rating. In addition to their use on construction sites, an excavator can also be used for heavy lifting in other industries, such as mining. An excavator can also be used for the following: material handling, demolition, landscaping, and river dredging. Excavators bring performance, flexibility, and versatility to the job site. With superior digging power, this heavy construction equipment is vital on any large jobsite and with surprising ease of use, excavators can also function in a variety of applications with the many multifunction attachments available for breakers, backfilling, digging, grading, loading, and dumping.

Mini excavators are made for jobs with limited working area. Despite their compact size, they can be used to accomplish many jobs such as excavating and moving rubble, rocks, gravel and dirt or even demolition. Mini excavators consist of a boom arm, a cab and a bucket and support various attachments, such as hammers, hydraulic thumbs and grapplers, for different jobs.

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:
