Abstract: In the article the variants of braking systems of dump trucks with payload from 218 to 255 tons are considered. In this payload range caught dumper Komatsu HD 830E AC, 860E-1K (Japan), Hitachi EH 4000 (Japan), BelAZ-7530, 7531 (Belarus), Liebherr T264 (Germany), Caterpillar 793F (USA). During the review it was established that dump trucks with payload capacity from 218 to 255 tons are traditionally equipped with four braking systems: working, parking, reserve and auxiliary. The service brake system provides a full stop. The parking system is used to stop the truck when parking, loading and unloading. The reserve system is an emergency system. The auxiliary brake system is designed to maintain the necessary speed on descents for a long time. The most commonly used braking system is the auxiliary braking system, represented by the dynamic braking unit. On the basis of the studied brake systems of dump trucks with carrying capacity from 218 up to 255 tons, it is established, that independent dump trucks also need to be equipped with working, parking, auxiliary and reserve brake systems.
