The excavator today is actively used in construction work. It performs a number of functions. Thanks to these machines, at the construction site, you can dig, load, pour out, and also perform many other actions.
Excavators are of two types – continuous and periodic machines. The components of this construction machine is the chassis, rotary mechanism and working equipment. The main characteristics of the excavator are laid in the indexing system. Quite extensive data on the construction machine is laid in the index structure. The letter designation of the type of excavator is initially indicated. Next are 4 digital index, having their own individual decoding. These numbers mean dimension, type of machine device, design of working equipment and, accordingly, the serial number of the model. The indexation is completed by another 2 letters: the first indicates the next modernization of the excavator, and the second – to climatic execution.
Types of the running device are indicated by numbers in the range from 1 to 9. Each of the numbers has its own meaning. The performance of the working suspension is indicated by several digits (1-3), depending on the type of equipment – hard, flexible or telescopic. In favor of what type of equipment the choice will be made depends on the type and features of those work that require the performance.
For example, excavators equipped with a straight line and reverse shovels have a flexible working suspension. The equipment of a straight shovel is widely used for digging pits in strong rocky rocks. Excavators equipped with a reverse shovel are used to form narrow trenches. The hard suspension of the excavator allows you to equip the equipment with additional elements. For example, a hydraulic mine.
In addition to one -brown excavators, there are still trenches. These construction vehicles are more productive and actively used for the formation of underground utilities. Indexation of trenches excavators is in many ways similar to single -bucket machines, but there are a number of features.
There is another type of construction vehicles – mini -excavators. Due to small sizes, maneuverability and cross -country ability, they are actively used in subway, basements of houses, in ports. Today, this type of equipment is gaining more and more popularity.
