i4500 Lattice Boom Crane
Instruction Manual
4.4.7 Bypass/Rigging
4.4.7.1 Rigging Mode (Maintenance / Erection Mode)
Warning! When in rigging mode, the motion cut and
overload alarms are disabled. In this condition, the crane
is not fully protected by the i4500, therefore it’s absolutely
essential to follow the crane manufacturer’s advice
regarding lifting the block, the rotation or the use of the
outriggers .
The Bypass/Rigging button is used to access the Rigging Mode,
to override an Overload Condition or to override an ATB
condition. In the case of an emergency the operator can override
the system (lockout) by pressing the Bypass / Rigging button.
The Bypass/Rigging button must be released and pushed again
after 10 seconds.
It is often necessary to go outside the “safety zone”for which the crane manufacturer
provides ratings when stowing or erecting the machine For example, the boom
stowed position may be outside the maximum load radius or minimum boom angle
specified on any load chart.
For this reason, the i4500 provides a Maintenance/ Erection mode where the
boom may be lowered to the horizontal position without having the external alarm
continuously sounding or the motion cut operating.
It is important to note the following points when the rigging mode is
activated:
• There are no lockouts
• The ATB switch is still monitored but will not active the lockout system.
• No audible alarms.
• The yellow light is on.
• The speed of the movements is not limited .
• A flashing rigging message is shown on the display.
• The rigging mode can only be accessed when the SWL is zero..
