Novations in creation and ensuring the competitiveness of BELAZ quarry machinery

The development tasks of OJSC “BELAZ” – Management Company of Holding “BELAZ-HOLDING”, are defined, which consist in using and introducing the latest achievements in the field of technical sciences and innovative technologies created on their basis into the design and production processes of mining equipment; development of new competitive products and promising sales markets, diversification of exports. Together with scientific organizations, studies have been carried out that have allowed us to develop new and improve existing methodological approaches to solving urgent problems in all problematic areas of creating modern mining dump trucks especially and in excess of extra heavy lifting capacity. OJSC “BELAZ” is the only manufacturer and supplier of dump trucks with a carrying capacity of 450–500 tons. As a result of research on the creation of such machines, the model of a short-base maneuverable dump truck with a rigid frame of a special design was first recommended, which reduces the center of gravity and loading height of a mining dump truck, designed according to the 4 × 4 scheme (two drive axles) with double axle busbar and the use of existing tires with a maximum carrying capacity of 104 tons. The proposed and comprehensively tested new layout solutions give reason to believe that the development of dump trucks with a carrying capacity of up to 600 tons is a reality when mastering the production of tires with a carrying capacity of more than 110 tons. А new generation of dump trucks with hydromechanical transmissions is designed; work is underway to create robotic complexes for the mining industry. Particular attention is paid to computerization, digitalization and environmental friendliness of mining equipment, ensuring the reliability of technology by creating and applying new structural materials and technologies for large parts and systems.
