 The Liebherr T 282 B and Bucyrus MT6300AC both match the Caterpillar 797F's payload capacity, but employ diesel/electric powertrains in contrast to the 797F's diesel-powered, mechanical powertrain.Both fall short of the BelAZ 75710's 500 short ton capacity, the largest of any haul truck in the world, which also employs a diesel/electric powertrain.Depending on customer requirements, lower payload capacity products such as the Komatsu 960E-1 and Belaz 75600 may also place competitive pressure on sales of the 797F.
