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)

Source summary

Develop a swing-drive package for the BE1000-1 100-ton hydraulic excavator, including motor, gearbox and spring-applied hydraulically released parking brake for its closed-loop circuit. The source asks to reduce continued swing after the joystick returns to neutral from roughly 35–40 degrees to 10–15 degrees. These are the requested stopping targets, not tested results.
