Telescoping the Boom

For a review of the mechanics involved in extending and
retracting the boom, refer to Telescope System Overview,
page 3-133. Refer to Main Menu, page 3-21 and Telescope
Submenu, page 3-32 for information on using the ECOS
system.
Telescope Mechanism
The telescoping process requires locking and unlocking of
the telescope cylinder assembly with the sections of the
main boom. You can telescope the main boom in two ways:
• Manual Telescoping, refer to Manual Telescoping,
page 3-138
For manual telescoping, you must initiate all locking
and unlocking processes at the right time.
• Telescoping with
Telescoping with Teleautomation, page 3-135
When telescoping with teleautomation, you enter
the telescoping requirements and the ECOS sys-
tem controls all the locking and unlocking pro-
cesses automatically. You may additionally need to
telescope to an intermediate length manually.
Fixed Length, Intermediate Length, Telescoping
Length
There are Load Chart tables for main boom fixed lengths,
main boom intermediate lengths and main boom telescoping
lengths.
The lengths are automatically detected by the RCL, and the
corresponding lifting capacities according to the Load Chart
tables are enabled and displayed automatically.
• Main Boom Fixed Length
Main boom fixed lengths have the greatest lifting
capacities. A main boom fixed length is reached if:
- All telescopic sections are locked to a fixed length
and,
- All telescopic sections are engaged with the locking
pin notch.
• Main Boom Intermediate Length
A main boom intermediate length is reached if all

OPERATING CONTROLS AND PROCEDURES
telescopic sections are not locked to fixed lengths.
- Extend the main boom to the required length before
hoisting the load!
- You cannot telescope the boom with the specified
lifting capacities for main boom intermediate
lengths.
• Main Boom Telescoping Length
The main boom is at a telescoping length if it is
extended to an intermediate length and may be
telescoped with the current load. The size of the
load that can be telescoped depends on the angle
of inclination and on the degree of lubrication of the
main boom.

to
The displays (1) to (5) show the current telescoping of the
telescopic sections 1 to 5 in percent, e.g. 50%.
Fixed and intermediate lengths differ in the locking pins (6):
• Green: Fixed length
• Black: Intermediate length
• Flashing: Telescopic section at fixed length with the
locking pin not engaged to the section or unlocked
