11.5.6 Telescoping mechanism
A telescoping process requires locking and unlocking processes in the main
boom. You can telescope the main boom in different ways.
– Manual telescoping
For manual telescoping, you must initiate all locking and unlocking proc-
esses at the right time.
– Telescoping with semi-automaton
When telescoping with semi-automation, you enter a telescoping value
and CCS controls all the locking and unlocking processes automatically.
You may then need to manually telescope to an intermediate length.
– Telescoping with pre-selection
When telescoping with pre-selection, you can enter several parameters
for lifting the load and the CCS suggests corresponding telescopings that
you can use as the starting point for semi-automatic teleautomation. Tel-
escoping with pre-selection has no independently selectable menu. The
parameters are entered when entering the rigging mode at the RCL and
the telescope status displays are in the RCL
Monitoring menu.
This is operated using the control lever. The control unit
CCS still forms part
of the operation.
Here you initiate processes, receive feedback and can
monitor the telescoping process.
The
CCS display shows various sectional views of the main boom. To make
you familiar with these representations more quickly, the following section
begins with an overview of the telescoping mechanism and a telescoping
process.
