Justification of parameters of excavator and car complexes

The paper considers the relationship between the main parameters of excavatorautomobile complexes. It is shown that with an increase in the productivity of excavatorautomobile complexes, the ratio between the parameters of mining excavators and dump trucks changes significantly. A rational relationship between the capacity of the excavator bucket and the load capacity of dump trucks is substantiated, based on the condition for increasing the productivity of the excavator-automobile complex. The efficiency of the EAK in specific operating conditions depends on the degree of use of the carrying capacity and capacity of the body of transport vehicles. Cargo platforms of mining dump trucks can have a different shape, size and payload. This is due to the physical and mechanical properties of cargo, mining technology and operating conditions of loading and transport vehicles. Manufacturers can equip mining dump trucks of the same line with the same load capacity with bodies of several standard sizes. The fact that the manufacturer has several body kits with different cargo capacities is due to the operating conditions of dump trucks, work experience and customer requirements. Therefore, there is a need to assess the compliance of the weight and size parameters of dump trucks (payload and body capacity) with the physical and mechanical properties of the cargo, technology and mining conditions. The results of the work can be used when choosing the parameters of excavator-automobile complexes.

Keywords: excavator-automobile complex, mining excavator, bucket capacity, load capacity of a dump truck, number of loading cycles.
