11.3.7 Telescoping mechanism
A telescoping process requires locking and unlocking processes in the main
boom. You can telescope the main boom in two ways.
– Manual telescoping
For manual telescoping, you must initiate all locking and unlocking
processes at the right time.
– Telescoping with teleautomation
When telescoping with teleautomation, you enter a telescoping value and
ECOS controls all the locking and unlocking processes automatically.
You may then need to manually telescope to an intermediate length.
With both ways, control is possible on the
ECOS control unit in addition to
the control levers. Here you initiate processes, receive feedback and can
monitor the telescoping process.
The
ECOS 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 tele-
scoping process.
