4.4.4.2 Moment percent more than 110%
If the moment percent shown on the load moment limiter is more than 110%, it means that the
actual load of crane exceeds 110% of the rated load. At this time, crane movements “spool up
H1, H2 and H3”, “derrick boom up and down” are cut off, the tricolor light sends out yellow and
red warning and the buzzer sounds continuously.
CAUTION
Bypass those limited movements in accordance with the following method:
Turn bypass switch (in the electrical control box of slewing table) clockwise until the
icon appears on the load moment limiter. At this time, all limited movements are
bypassed. However, the tricolor light sends out red warning and the buzzer sounds
continuously.
4.4.4.3 Moment percent less than 100%
When crane is not lifting the rated load, please see section 4.4.4.1.
CAUTION
(1) Once the limited movements are bypassed by bypass switch, their speeds will be
reduced to 15% of original speed.
(2) Press “Setup” switch, the bypass of cutoff is valid. After the limited movement is
bypassed, return the control lever for 10s, or press “Setup” switch again, or the
engine stops, or the controller is electrified again, the bypass of cutoff is invalid.
Press bypass switch, the bypass of cutoff is valid for 30mins. If the switch is
pressed again, or the engine stops, or the controller is electrified again, the bypass
of cutoff is invalid.
4.4.5 Boom angle indicator
Boom angle indicator is fitted on the lower rear end of main boom pivot section (i.e. on the right
side of the crane operator’s cab). In this way, the operator, even in crane operator’s cab, can
clearly read boom angle shown on the indicator.
For reference only.
Operators manual should be consulted and adhered to.
