4. FLY-JIB INSTALLATION AND STOWAGE
• It is recommended that two operators perform the installation and stowage work of the Fly-jib.
Prior to operation, discuss each person’s duties in detail and follow the agreed signals during
the operation. If signals are not clearly understood, it may cause an accident resulting in injury
or death.
• Fly-jib installation and stowage must be practiced on solid level ground. Otherwise, the Fly-jib
may turn under its own weight and cause a serious hazard.
• Fly-jib installation and stowage require a rigid stepping stool of sufficient height. An unstable
stool may result in the user falling from a height and may incur serious personal harm.
• For Fly-jib installation and stowage, it is essential to keep the main boom angle level.
Otherwise, when the boom is not kept level, the weight of the Fly-jib itself will make it turn
which may result a serious accident.
• The Fly-jib is installed to the Main boom with four position pins. The Fly-jib consists of two
sections and another position pin fixes the 1st and 2nd sections. Prior to starting operation,
always ensure these three position pins are inserted in the correct positions and secured by
their linchpins. Otherwise, if any of the pins drops out, the Fly-jib will drop which may cause a
serious hazard.
• The Fly-jib tilt angle is adjustable from the stowage position to four (4) positions (0, 20, 40 and
60 degrees), and one postion pin is used to fix it. When the Fly-jib angle is adjusted to the
intended tilt angle, insert the position pin to the correct location and secure it firmly with it’s
linchpin. Otherwise, when the position pin drops out, the Fly-jib will collapse, which may
result a serious accident.
• Whenever the Fly-jib is installed, it is essential to re-connect the over-hoist detector harness
from the Main boom detector to the Fly-jib detector. Always ensure the over-hoist detector of
the Fly-jib is working correctly before starting operation. In the event that the over-hoist
detector mis-functions, it may cause the hook or hoisted load to drop and result in a serious
hazard.
• Whenever the Fly-jib is installed, it is essential to re-connect the Fly-jib detector harness from
the connector in the Fly-jib to the one in the Main boom. In the event that the moment limiter
fails its correct functions, that may cause the hook or hoisted load to drop resulting in death or
serious injury.
• The Fly-jib is stowed to the side of the Main boom and fixed to it with four position pins. When
installing or stowing the fly-jib, always ensure all four position pins are inserted in the correct
position and secured by their linchpins. Otherwise, if any of the pins drop out, the Fly-jib will
become detached from the main boom and fall off, which may cause a serious hazard.
• When the Fly-jib is stowed, always re-connect the over-hoist detector harness from the Fly-jib
detector to the Main boom detector. Always ensure the over-hoist detector of the Main boom is
working correctly before starting operations. Should the over-hoist detector mis-functions, it
may cause the hook or hoisted load to drop resulting in a serious hazard.
• Whenever the Fly-jib is stowed, it is essential to re-connect the Fly-jib detector harness from
the connector in the Main boom to the one in the Fly-jib. In the event that the moment limiter
fails its correct functions, that may cause the hook or hoisted load to drop resulting in death or
serious injury.
CAUTION
The lever block (23) included in the accessories shall be set
to the bracket between the tilt angle adjuster outer rod and
inner rod, for the purpose of changing the Fly-jib tilt angle.
For the use of the lever block, refer to the attached manual.
