Micro excavators are small machines designed for light work and to fit into tight spaces. They are commonly used in small construction projects and landscaping. They can be tracked or wheeled and are powered by diesel, LP gas or electricity. They can handle various attachments such as augers, rock breakers, and pincers.
A micro excavator is a type of excavator designed for light work or to fit into areas inaccessible to larger machines. A typical micro excavator is capable of accommodating a driver in an open cockpit or enclosed cab and is equipped with a backhoe with a relatively small bucket. These machines are designed in much the same way as the larger excavators used in mining and construction, but on a much smaller scale and can be small enough to fit through a standard doorway. They are often available for rent through equipment rental companies.
Several companies build machines of this type and they are common on small construction projects and any project where an excavator is required but larger machines cannot access. A micro excavator is suitable for residential projects such as landscaping as most can pass through garden gates and narrow spaces between houses and fences or hedges. In some cases, they can even be used indoors as some are small enough to fit through standard doorways and are light enough to be used across many floors. Most micro excavators weigh less than 2500 lbs (1100 kg).
Most machines in the micro-excavator class are designed in one of two configurations, both of which mimic larger excavators. A micro excavator can be tracked or wheeled, although most machines of this type are tracked. A front loader-rear excavator combination will have a rear excavator at the rear of the machine and a dozer blade or front-loading shovel at the front. Other micro excavators have a backhoe mounted to the front of the vehicle and may also have a small dozer blade. The operator usually sits in an open cockpit atop the excavator body, but may be protected by a rollbar or roll cage, which can fold down to reduce the profile for access to tight spaces.
Depending on the manufacturer, a micro excavator can be powered by any of several types of engine, including diesel, liquid propane (LP) gas, and electricity. Micro excavators are often capable of handling a variety of attachment tasks in addition to digging. Some of the most common are augers, for digging cylindrical holes for posts or pilings, rock breakers, and pincers, which are claw-like assemblies for gripping objects. A root tong, a type of tong designed to grab masses of roots and pull them out of the ground, is a common specialty tong attachment.
