CAUTION
• The machine weight depends on the machine
configuration.
The weight table on the right shows the weight
of the standard vehicle and additional weight of
respective accessory units.
• The Fly-jib tilt angle is adjustable to four (4) positions (0, 20, 40 and 60 degrees).
During the Fly-jib operations, always keep the boom angle in the range as specified below:
[At the Fly-jib angle in 0 or 20 degrees]
Perform the crane operation within the boom angle range of “45 degrees” or more. When a
load is hoisted in a condition that the boom angle is less than “45 degrees” and the boom
length is “5.3 m” or longer, the moment limiter emits a warning signal, the buzzer sounds
intermittently, and hook hoisting, boom telescoping and boom lowerring operations
automatically stop.
However, when the boom length is less than “5.3 m”, the moment limiter does not emit a
warning signal. In a condition where the boom angle is less than
“
45 degrees", boom lowering
operation is not available unless the boom length is less than “5.3 m”.
[At the Fly-jib angle in 40 or 60 degrees]

load is hoisted in a condition that the boom angle is less than “65 degrees” and the boom
length is “5.3 m” or longer, the moment limiter emits a warning signal, the buzzer sounds
intermittently, and hook hoisting, boom telescoping and boom lowering operations
automatically stop.
However, when the boom length is less than “5.3 m”, the moment limiter does not emit a
warning signal. In a condition where the boom angle is less than “65 degrees”, boom lowering
operation is not available unless the boom length is less than “5.3 m”.
