An excavator can either be mounted on wheels or on tracks. These are used to facilitate for its mobility and are used in different environments. Track hoes are the type of excavators that are mounted on tracks. Excavators are not only used in construction industries but can also be used in the mining industry and also for lifting heavy loads. Other common uses of excavators include; river dredging demolition landscaping and also material handling. Excavators come in different types and sizes depending on the different jobs they can be employed on. Small excavators are commonly called mini or compact excavators and often come equipped with a bulldozer blade at the front. The smallest type of mini excavators is capable of fitting through a doorway. In contrast the largest type of excavators can weigh an amazing 180000 lbs. Compact excavators can be found in 2 distinct types namely the tail swing and zero tail swing models. Conventionally all compact excavators were tail swing models and had an attached rear counterweight to prevent them from tipping while digging.
Excavators are of great importance in construction sites. Excavators are made up of many parts that work together to get the job done. Main Parts of an Excavator As mentioned an excavator has many parts that work together to get the job done. The most common parts are: Motor: it creates the power used in moving an excavator. The motor can be powered by petrol fuel or even electricity. Its good to note that while there are electric excavators in the market they are very rare and they are designed to work in specialized areas. The hydraulic motor is one of the most important motors in an excavator. This is the motor that raises and extends the excavator arm.
Back Hoe For excavation purposes construction engineers make use of back hoes which are the most common types of excavators used today. This excavator has a bucket attached to the front which is facing the driver. This position of the bucket allows the driver to have a clearer idea of the excavation. Back hoe excavators are part of almost every construction site and due to their incredible ability to dig through soil they help improve productivity and save costs. The cab of this machine can swiftly rotate to 360 degrees making it easier for the driver to transport the debris to the dumping zone. Back hoes are also used for clearing snow covered roads and to clear blockages.
The other terms used for excavators are diggers and 360-degree excavators. They are sometimes simply called 360. The tracked excavators are also called track hoes due to its resemblance with a backhoe. There is a contradiction that the back in a backhoe is used in reference to the pulling back action of the bucket towards the machine instead of the location of the shovel. However excavators are still referred to as front hoes by some people. Excavators come in a variety of sizes but the most popular are large excavators and mini excavators. The large excavators are huge in size. They weigh around 85000 kg and their bucket size is usually 4.5 m 3. These excavators are generally used for industrial excavation works.
