4. MOUNTING AND STOWING FLY JIB
• We recommend to mount or stow a fly jib with two persons. They must fully check the work
content mutually and perform the operation based on the designated signals. If the signals
are insufficient, they may contact a moving part, which can cause a serious accident.
• Stop the engine before mounting or stowing a fly jib.
Otherwise, malfunction of the electric wires or hydraulic equipment may occur, causing
unexpected operations or serious accidents.
• Mounting and stowing a fly jib should be conducted on a leveled and firm ground. Otherwise,
a fly jib can rotate by its own weight causing a serious accident.
• Mounting and stowing a fly jib should be conducted on a stable work table with sufficient
height. If you use an unstable work table, a fly jib can fall from a high place. causing a serious
accident.
• When mounting or stowing a fly jib, make sure the main boom is in a horizontal position.
Otherwise, a fly jib can rotate by its own weight causing a serious accident.
• A fly jib is attached to the main boom with 4 position pins. Insert four position pins in the
correct positions and tighten them securely with a linchpin and shaft lock pin. If the position
pin comes off, the fly jib may fall, causing a serious accident.
• When mounting a fly jib, be sure to disconnect the electric wires from the over-hoist detector
on the main boom side and reconnect them to the fly jib side. If the wires are not connected
correctly, the moment limiter or over-hoist detector will not function properly, causing a
serious accident.
• Fly jibs are attached and stowed to the main boom with three position pins. Please check that
the three position pins are correctly inserted and tightened securely by a linchpin. If the
position pin comes off, the fly jib may fall, causing a serious accident.
• When stowing a fly jib, be sure to disconnect the electric wires on the fly jib side and
reconnect them to the over-hoist detector on the main boom side beforehand. If the wires are
not connected correctly, the moment limiter or over-hoist detector will not function properly,
causing a serious accident.
