7558 SERIES CHARACTERISTICS

Designed for transportation of loosened rocks on technological haul roads at open-pit mining sites under different climatic conditions. These trucks can be used in construction of large industrial structures and hydraulic facilities, in construction of highway systems as well as in technological departments of the enterprises of processing industry. Depending on relative density of the transported materials maximal efficiency is achieved during operation with excavators and loaders with the following bucket capacity: 12.8 — 18 m³.
