18000 SERIVCE/MAINTENANCE MANUAL INTRODUCTION
1
When in a swinging motion, the preferred way to stop or slow
crane is to move swing control handle beyond center in the
opposite direction. This allows upperworks to gradually stop.
Swing Holding Brake Switch
Swing holding brake switch on side of swing control handle,
holds upperworks in position (applies swing park brake) for
short periods when operating. To prevent damage to swing
system, swing holding brake switch must only be applied
when crane is at a standstill.
When holding brake switch is pressed in and held, an input
voltage is sent to node-1 controller. Node-7 controller sends
a zero output voltage to shift swing brake solenoid HS-32.
Swing brake solenoid valve shifts to block fluid to brake and
swing brake is applied.
When swing holding brake switch is released, an input
voltage is sent to node-1 controller. Node-7 controller sends
a 24 volt output to shift swing brake solenoid HS-32. Swing
brake solenoid valve shifts, allowing system pressure to
hydraulically release park brake.
