The anti-two block (A2B) indicator appears on
the screen of the i4000 when the hook pulley is
near the boon head pulley. This may block the
hoist function and the booming down depending
on crane model and/or on the options fitted on
the machine.
The rope’s capacity limit indicator appears on the
screen of the i4000 system to indicate that the
allowed nominal load is limited by the rope’s safe
operation limit. Increase the number of strands
(parts of line) between the head pulley and the
pulley block, and change the number of strands
on the i4000 system to turn off this indicator and
thus increase the crane’s nominal capacity.
A warning message will be displayed on the other tabs (INDICATOR
and RANGE LIMITING DEVICE) in order to inform the operator
that an ATB has been detected.
