Excavators are construction vehicles used in various construction activities like road construction for digging and the moving material on the site. They are also commonly referred to as backhoes or diggers called so because they use wire rope or a hydraulic system to dig holes and trenches. An excavator has a long boom arm that is mounted on a pivot and connected at an elbow to a stick that holds the bucket. The bucket is an attachment and can be removed and replaced by a different accessory depending on the specification of the work being done. The excavator can be used for different operations at the construction site. The cab of an excavator can rotate a full 360 degrees. For this reason another common name for an excavator is the 360 degree digger.
The Dragline Excavator may come in smaller or bigger types. Smaller types are employed in civil engineering to construct road and port. While the larger types are utilized in strip-mining to move overburden above coal and for tar-sand mining. Draglines usually weigh about 2000 metric tons but there are also bigger draglines weighing 13000 metric tons. The bucket system of a dragline has a large bucket suspended with wire ropes from a large truss-like structure called boom. This bucket is maneuvered by ropes and chains and is supported by a hoist rope (whose power comes from large diesel or electric motors). The dragrope is responsible for holding and drawing the bucket assembly in a horizontal fashion. A skillful operator may apply his skills in contriving the ropes for the dragline to perform various operations.
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 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.
