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