Published 02-21-2019, Control # 611-05
Releasing the swing brake
- With the brake pedal function
The swing brake is released when you switch on the
swing gear.
Lamp (1) will extinguish if the swing brake has been
released.
Applying the swing brake
- The swing brake is applied when you switch off the
swing gear, refer to Switching off the swing gear,
page 4-83.
The lamp (1, Figure 4-162) will light up if the swing brake has
been applied.
Swing
The following requirements must be fulfilled before swinging:
- The houselock must be disengaged, refer to
Switching off the 360° lock, page 4-41.
- Swing must be permissible with the current rigging
mode.
- The current rigging mode must have been entered
on the RCL display.
Releasing locked swing gear
You can unlock the swing gear if it has been locked.
Press and hold the button (1, Figure 4-163) – the swing gear
is unlocked. The speed will then be reduced to 10%.
The anti-two block bypass can override swing lockout in the
case of:
• Counterweight cylinders not up
• Carrier avoidance (boom low enough & close enough to
hit the carrier cab or exhaust stack)
You can adjust the sensitivity of the control levers to suit the
operating conditions, refer to Setting the characteristic
curves for the control levers, page 4-84.
NOTE: Slewing movements are not braked automatically.
If you let go of the control lever or move it to initial
position, the swing movement will gradually slow
down, refer to Braking the swing movement, page
4-82.
WARNING
Tipover Hazard!
Before swinging, always check whether the RCL code is
valid for the current rigging mode displayed.
This prevents swing operations from being enabled within
the impermissible ranges, which would cause the truck
crane to overturn.
DANGER
Crush Hazard!
Death or Serious Injury could occur if struck by moving
machinery.
