Telescoping - Theory of Operation
The following section describes the internal operation of a
pinning boom.
The telescoping process requires locking and unlocking
processes in the main boom. The main boom can be
telescoped in different ways.
Manual Telescoping
For manual telescoping, the operator must initiate some
locking and unlocking processes at the right time.
Semi-automatic Telescoping
When telescoping with semi-automation, the operator enters
a telescoping sequence or “tele picture” and Crane Control
System (CCS) controls all of the locking and unlocking
processes automatically. This mode can also be used for
intermediate lengths.
NOTE: For more information on telescoping with
semi-automation refer to Telescoping with
Semi-automation, page 4-39.
Extending with the Main Boom Configuration
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.
Overview
This illustration (Figure 4-9) shows the completely retracted
main boom with the base section (9) and the first three
telescopic sections I to III (1) to (3).
DANGER
Crushing Hazard!
When retracting the boom, the load will lower unless the
hoist rope is taken in at the same time
