Steering
Hydraulically actuated, multiple-disc oil clutches with 24 friction surfaces in each clutch. Oil-cooled contracting band brakes. Floor-mounted controls.


Counterweights

Adjustable, hydraulically controlled
Counterweight & lift frame . . . . 1,610 kg / 3,560 lb.
8 segments at 600 kg / 1,330 lb each . . . . 4,830 kg / 10,640 lb
Total weight extendable . . . . 6,440 kg / 14,200 lb

Full hydraulic control. High mounting counterweight pivot point gives excellent side and bottom clearance. Over-center design prevents creep-out when retracted. Minimum overall width for easier maneuvering and shipping.



Undercarriage
Sealed Track extends pin and bushing life and reduces wear on links and rollers. Track rollers, carrier rollers and idlers are Lifetime Lubricated. Sprockets have bolt-on rim segments.

Number of track rollers (each side) . . . . 6
Track guage . . . . 2180 mm / 86"
Track shoe width (standard) . . . . 610 mm / 24"
Optional width . . . . 660 mm / 26"
Track length on ground . . . . 2830 mm / 111.37"
Ground contact area (standard shoes) . . . . 3.45 sq.m. / 5,345 sq. in.
Ground clearance from ground face of shoe . . . . 483 mm / 19"
Grouser height from ground face of shoe . . . . 71 mm / 2.81"


Boom control
Safety pawl holds boom drum. Interlock prevents accidental reversal with pawl engaged. Safety kickout prevents boom bending.


Caterpillar Engine
Flywheel power @ 2000 RPM..........................149 kW/ 200 HP
(Kilowatts (kW) is the International System of Units equivalent of horsepower.)
