Telescoping The position of the telescopic sections (1) to (6), i.e. which telescopic section
is extended to what extent, is referred to as telescoping.
This section only deals with the displays on the RCL. The telescoping is also
shown on the
ECOS display; Ã p. 11 - 86.
The RCL displays main boom fixed lengths and main boom intermediate/
telescoping lengths in different ways.
Fixed lengths
Possible fixed lengths are 0%, 50% and 100%.
The locking pins (7) are green.
Intermediate lengths
Telescoping
sequence
The telescopic sections (1) to (6) can only be telescoped individually, one
after another.
When extending you must always extend the telescopic section with the
highest numbering first, then the telescopic section with the second highest
numbering, etc. (e.g.
IV, III, II, I).
The telescopic sections are always retracted in the reverse order of
extending.
A Locking pins (7) are black –
e.g. at 35%.
B Locking pins (7) are flashing –
e.g. to 50% and telescopic section is
– unlocked or
– not set down.
