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.
