UPPERSTRUCTURE

Revolving Frame

Welded sturdy box construction, using heavy-gauge steel plates for ruggedness. D-section frame for resistance to deformation.

Swing Mechanism

Axial piston motor with planetary reduction gear is bathed in oil. Swing circle is single-row, shear-type ball bearing with induction hardened internal gear. Internal gear and pinion gear are immersed in lubricant. Swing parking brake is spring-set/ hydraulic-released disc type.

Swing speed ………………………………………………….13.7 rpm (min-1)

Operator’s Cab

Independent roomy cab, 40” (1 005 mm) wide by 66” (1 675 mm) high, conforming to ISO Standards. Reinforced glass windows on 4 sides for visibility. Front windows (upper and lower) are openable. Adjustable, reclining seat with armrests; movable with or without control levers.

Undercarriage

Tracks

Tractor-type undercarriage. Lubricated track rollers, idlers, and sprockets with floating seals. Track shoes with triple grousers made of induction-hardened rolled alloy. Heat-treated connecting pins with dirt seals. Hydraulic (grease) track adjusters with shock-absorbing recoil springs.
