An additional feature of the MicroGuard
424 System is the provision of Operator Settable Alarms. These
alarms, when properly set by the operator, provide a method of obstacle avoidance. This is achieved by
means of minimum and maximum angle, maximum length and maximum height alarms. These alarms can be
programmed for each job site and set rapidly for the prevailing site conditions, thereby aiding the operator in
the safe operation of the crane.
Most alarms will occur automatically as a result of limitations imposed by the capacity chart. The operator has
control over additional alarms, which are set to define the working range of the machine for particular site
requirements, and which will provide a measure of obstacle avoidance.
Four alarms are available for operator use.
