Design Development of Swing Drive (Swing motor Gear box Spring applied hydraulically released parking brake) suitable for closed loop swing circuit on BE1000-1 Hydraulic Excavator (100-ton class Excavator)
Presently, Swing brake angle is 35 to 40 deg. when the joy is returned to neutral while the upper structure of the excavator is swinging. Whereas, the requirement is Swing brake angle shall be within 10 to 15 deg. when the joy is returned to neutral while the upper structure of the excavator is swinging.
