C. Swing Lockout Device
The swing lockout device attaches on the right side of the superstructure. It can lock
the turntable in the 360° range. You use the swing lock switch (on the cab dash panel)
to engage or disengage the swing lockout device.
When the swing lock switch is in the LOCK position, the superstructure cannot move
left or right.


Make sure that you do not make fast movements or suddenly stop the turn.
 When you operate a new crane, make sure that you do a check of the
Maintenance Log. The swing bearing bolts must be examined at these intervals:
100, 500, 1000 hours of operation.

The torque on the bolts must be 700 lbf· ft (950 N· m).
 The crane can turn with a load above the ground. Do not try to lift the load
diagonally. Do not pull a load across the ground.

Make sure that the outriggers are in the correct position and RCI is set to the
proper configuration before you swing the superstructure with a load on the
boom.

Monitor the area as you move a load. Do not move a load unless the conditions
are safe.

Before you swing the superstructure, make sure that the swing lockout device
is in the UNLOCK position. When the crane movements stop, lock the
superstructure and ensure the swing lock indicator illuminates.
Before you lift and move a load, make sure that the wind and weather conditions are
safe to operate.
