Updated Rigid-Body Mine Truck
Komatsu America Corp. recently released
its HD1500-7 truck to the international
mining market. The truck’s standard turbocharged
Komatsu SDA12V160 diesel
engine delivers 1,487 hp (1,109 kW) at
1,900 rpm, and an optional SDA16V159
engine offers North American customers
U.S. EPA Tier 2 certification. Nominal
payload is 158 t (143 mt). Komatsu says
the HD1500-7 provides 4% more horsepower,
providing a 10% speed advantage
on a 12% incline at maximum GVW.
Downhill, the difference is even greater,
with the HD1500-7 providing an 18%
speed-on-grade advantage while traversing
a negative 10% effective grade, fully
loaded. The HD1500-7 features an
enhanced engine damper assembly and a
seven-speed, electronically controlled
transmission. Both front and rear propulsion
shafts have been strengthened, and
the final drive offers beefier planetary
gear teeth and shaft diameters to handle
the truck’s torque output. The HD1500-7
is also claimed to have the tightest turning
diameter in its class.
