The 30.9-ton capacity Komatsu HM300-5 uses the Komatsu
Traction Control System, two working modes (Power and Economy)
and a standard payload meter (PLM). (Inset) Komatsu's
Traction Control System is turned on and
off with a dash-mounted rocker switch.
(Right) The turning ring, or oscilla-
tion joint, in Doosan's ADTs allows
extreme angles between the cab
and the dump body.
(Above) Doosan's use of three
turning rings allow all six wheels to
remain in contact with the ground
even under severe conditions.
