World class ekskavatorostroeniya assessed before the main parameters, given in handouts: mass excavator, engine power, bucket capacity, the characteristics of hydraulic systems, and the rotation speed, parameters of the working area, dimensions of the excavator. A list of these parameters is consistent with the GOST 30067-93 "backhoe shovel universal full-circle. General specifications ". Samples of BDE was carried out by range of masses, since, as evidenced by the statistics, namely the mass depend strongly on other characteristics. In the GOST 30067-93 excavator operating weight is defined as the main parameter, depending on which Excavators are divided into size groups.

The mass range chosen so that the mass excavator EO-4225A-07, equal to 26.5 m, located approximately in the middle. This ensures a match (or close value), the estimated average statistical weight and mass excavator excavator EO-4225A-07. Rental of excavators JCB, as well as rental of construction equipment of another kind needed for your building site, available in the company of 'The Golden Age. " The first sample carried out in the mass range 22-32 m, includes 64 excavators 24 firms from 10 countries. Analysis of this sample showed that it needs sorting. In the BDE has a different prescription information on one model or similar models of excavators and one the same firm for the analysis of trends ekskavatorostroeniya. The first rule was that sort.

that are submitted for analysis only the new data. The number of models of excavators of different companies in different congeners and Hence, the difference in their proportion of the average estimate. The second rule was that sort that the sample should be equal to the number of shovels of each firm (preferably one with a mass, like an excavator EO-4225A-07). When sorting by the second rule it became clear that a number of leading mass excavators companies 'swaps' mass excavator EO-4225A-07 (so there is a model weighing 23 tons and below 30 tonnes). Exclude them from consideration can not, so it was use the third sort criteria, which consisted in the fact that such firms were considered two excavators, the average weight is close mass excavator EO4225A-07.
