Any operation that involves digging material could be called an excavation, we have listed equipment here that is most often used to dig more size limited excavations.
A backhoe loader, also called a loader backhoe or tractor backhoe, is a heavy equipment vehicle that consists of a tractor fitted with a bucket on the front and a small backhoe on the back. Due to its relatively small size and versatility, backhoe loaders are very common in urban construction projects. These machines travel on rubber tires, and can actually travel at speeds of approx. 25 mph/40 kmh. This makes these machines very popular where travel between worksites or excavations is required often.
These machines can dig small excavations, dig trenches, and using the loader attachment on the front of the machine can move material such as sand or gravel and can be used to can load trucks.
Dredging is the activity of excavating underwater bottom sediments and disposing of them at a different location. This technique is often used to keep waterways navigable or reclaim land. There are several types of dredgers available.
Excavators, also known as a track hoe, are heavy equipment consisting of a boom, dipperstick, bucket and cab on a rotating platform. The cab sits atop an undercarriage with tracks or wheels. All movement and functions of the excavator are accomplished through the use of hydraulic fluid. The tracked excavator is very versatile in the mining, forestry, construction and pipeline industries.
Wheeled excavators offer mobility to travel up to 23 mph (37km/h) and can move quickly from job to job minimizing the need for additional transportation. They are ideally suited for a number of applications, like ditch cleaning or road maintenance that require travel while using a work tool.
