Features of mini excavators
Like all excavators, mini excavators will have an undercarriage, house, and boom. The undercarriage may be wheels, but is more frequently continuous track for improved stability over the uneven terrain of work sites. The house is the cab portion of the excavator. This is where the joystick-like controls are located. The house turns on the undercarriage via a hydraulic system. Unlike excavators, some models of mini excavators will have a counterweight on the rear of the house that extends beyond the undercarriage. Mini excavators with counterweights incorporated into the house are also available for spaces that will not accommodate the extra size of a rear counterweight.
The boom is the long arm, which extends from the front of the excavator. Mini excavators have the same boom options as excavators; straight booms move up and down and knuckle booms move horizontally as well as vertically. Mini excavators are also available with a hinge on the base of the boom to allow for rotation without moving the house. The attachment on the end of the boom is frequently a bucket, but there are other attachments available for various purposes. Buckets come with either a straight edge for smoothing or with teeth for breaking up material while digging. Examples of attachments are the following: a powerful hammer known as a breaker, a claw for grabbing, or an auger. These are available for mini excavators as well.
How mini excavators work
Once you have chosen your attachment, moving the stick controls in the house operates excavators. The boom has a hinge, which allows the bucket or attachment to reach out and scoop or hit the material. If the goal is to move material to a new location, the house can then be swiveled and the material released from the bucket. Mini excavators may also be used to ram and smash existing structures into smaller pieces before scooping them up for removal.
About mini excavators
Mini excavators, also known as compact excavators, are simply small versions of excavators for use in small spaces. Excavators are heavy equipment used primarily at construction sites. They are used to dig or break ground and materials in preparation for building. They have four main components: undercarriage, house, boom, and bucket. The house sits on top of the undercarriage and swivels 360 degrees. The boom is a long arm with a hinge in the middle that allows the operator to move the bucket attached to the end. Mini excavators frequently have a backfill blade on either the front or back of the undercarriage for leveling and grading.
