Английская Википедия:BelAZ 75710
Шаблон:Infobox automobile The BelAZ 75710 is an ultra class haul truck manufactured in Belarus by BelAZ. As of 2013, it was the world's largest, highest payload capacity haul truck.
Design
The BelAZ 75710 has a conventional two-axle setup but the wheels are doubled, one to an axle, imitating the 1950s International Payhauler 350. For this reason, it needs two 59/80R63 tires.[1] It also has four-wheel drive and four-wheel hydraulic steering which is unusual. It has a turning radius of about Шаблон:Cvt.[2]
The 75710 is claimed to carry a Шаблон:Convert load.[3] With an empty weight of Шаблон:Convert, it is much heavier than BelAZ's previous largest model, the 7560, which weighed Шаблон:Convert when empty.[4] [5] It is Шаблон:Cvt long, Шаблон:Cvt high, and Шаблон:Cvt wide. The bed is relatively shallow, limiting the volume of material that can be carried.
Instead of a single engine, the Siemens MMT 600 drive system is powered by two MTU Шаблон:Convert 16-cylinder four stroke diesel engines, each with Шаблон:Convert. These are coupled to two AC alternators and four AC traction motors (two in each axle.)[6] Fuel consumption (according to company data) is Шаблон:Convert, with the option to run on only one if carrying less than capacity loads. Maximum claimed speed is Шаблон:Cvt, and economy maximum speed (when fully loaded and on a 10% gradient) is Шаблон:Cvt.[7]
Project history
BelAZ produces the 75710 in a new facility constructed by Soligorsk Construction Trust No. 3. Overall, BelAZ has invested $954 million in increasing its total production capacity.[8]
Previously the world's largest haul trucks were the Bucyrus MT6300AC, Liebherr T 282B and Caterpillar 797F ultra-class trucks, with load capacities of Шаблон:Convert.[9]
