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 processes
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 lift-
ing the load and the CCS suggests corresponding telescopings that you can
use as the starting point for semi-automatic teleautomation. Telescoping 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 CCS control unit remains active as a
control element. 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.
