| Third pump circuit | 20.6 MPa (210 kgf/cm2) |
| Pilot circuit | 3.9 MPa (40 kgf/cm2) |
Hydraulic Cylinders
High-strength piston rods and tubes. Cylinder cushion mechanisms provided in boom raise and arm roll-in circuits to absorb shocks at stroke ends.
Dimensions
CONTROLS
Hydraulic pilot control levers for all operations.
SWING MECHANISM
High-torque, axial piston motor with planetary reduction gear. Swing circle is single-row, shear-type ball bearing with inductionhardened 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 | 9.7 min-1 (9.7 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
| Lower rollers | 3 |
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 (with rubber shoes) | High : 0 to 4.4 km/h Low : 0 to 2.7 km/h |
| Travel speeds (with grouser shoes) | High : 0 to 4.2 km/h Low : 0 to 2.6 km/h |
| Gradeability | 58 % (30 degree) continuous |
