OPERATING CONTROLS AND PROCEDURES
Hydraulic Boom Extension Operation — Remote
Station
When using the remote station (Figure 3-190) to operate the
hydraulic luffing jib, press the button until the desired angle is
reached or until the end position or a switch-off point is
reached.
To lower or raise the hydraulic luffing jib, using the remote
station:
- To lower the jib: push the right button,
- To raise the jib: push the left button.
Two Hook-Operation
Two-hook operation is permissible only when one of the
following is installed:
- Swingaway boom extension
- Auxiliary single-sheave boom nose
- Heavy load boom extension.
For two-hook operation, both hoists must be activated on the
RCL.
NOTE: Enter the reeving for both hoists before reeving the
boom. The values are stored and opened directly
when switching hoists. This eliminates the need for
input later during operation.
