Excavators are engineering vehicles which are primarily used for the purpose of digging trenches holes or foundations. They are also used for other purposes such as demolition lifting and placing heavy materials especially pipes for mining( not open pit mining) river dredging landscaping. These can be used for brush cuttings aided with hydraulic attachments. Because excavators are used for the purpose of digging people usually use the term excavators for all kind of digging equipments. Actual excavators have an articulated arm a bucket and a cab mounted on a rotating platform known as a pivot. This platform is on top of an undercarriage with tracks or wheels. The design is basically derived from steam shovels.
Thus with the availability of machines that can dig through different types of surfaces work will have a short duration. For the contractor this can mean more business can be tackled over a period of one month. There is only a need to find an operator who knows how to move the machine around in a few strokes. Excavators do not really need a lot of space to work around because they usually run on tracks where every little movement would allow it to execute a different move. The most important element for the space is the level of the ground where the excavator will stay since a mere bump on the ground can mean disaster for the excavator as it requires to move around on flat surfaces.
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.
