The combination of planetary truck and dump body has a lower capital and operating cost than articulated trucks in the same weight class. The lower operating cost is derived from the simple mechanics and lower parts cost due to large parts volume. The trucks gearing can be configured to give a good top speed and excellent torque to climb out of the pit.
The cycle time is kept to a minimum with an oversized PTO pump and hydraulic valving. The dump body shown is created for a 110,000 lbs planetary truck.
