SWING MECHANISM
High-torque, axial piston motor with planetary reduction gear.
Swing circle is single-row, shear-type ball bearing with induction-hardened internal gear. Internal gear and pinion are immersed in lubricant.
Swing parking brake is spring-set/hydraulic-released disc type. Swing shockless valve built in swing motor absorbs shocks when stopping swing, ensuring smooth stops.
| Swing speed | 9.3 min-1 (9.3 rpm) |
UNDERCARRIAGE
TRACKS
Tractor-type undercarriage. Welded track frame using carefully selected materials. Side frame welded to track frame.
NUMBERS OF ROLLERS ON EACH SIDE
| Upper roller | 1 |
| Lower rollers | 4 |
TRAVEL DEVICE
Each track driven by a high-torque, 2-speed axial piston motor through planetary reduction gear, allowing counter-rotation of the tracks. Travel shockless relief valve built in travel motor absorbs shocks when stopping travel, ensuring smooth stops.
| Travel speeds (rubber shoes) | High: 0 - 4.5 km/h Low: 0 - 2.8 km/h |
| Travel speeds (grouser shoes) | High: 0 - 4.2 km/h Low: 0 - 2.6 km/h |
| Gradeability | 30 degrees (58%) continuous |
