Lifting a load
As a load is lifted, the Load on Hook value as displayed on the screen
(item 7 on page 5)
will show the
weight of the load suspended from the hook. This load is compared to the Rated Capacity
(item 9 on
page 5)
, the calculated value that the machine is allowed to lift before an
“
overload
”
event occurs, and
the status bar
(item 14 on page 5)
will fill proportional to the % of the Rated Capacity currently being
used. As the machine changes position in terms of height, radius, cant, gradient or slew angle, the Rated
Capacity is continuously recalculated. Axle lock status and Road, Rail or LUL duty changes will also affect
the Rated Capacity value.
Overload
As the RCI detects that the Load on Hook value is approaching the Rated Capacity, the
AMBER LED
on the
side of the RCI display will light up and the internal buzzer will sound. As the Load on Hook value reaches
the full Rated Capacity value, the RCI will register an Overload state, which is signaled by the
RED LED
being lit and the external tipping alarm sounding. At the same time, any hydraulic service which will take
the machine further into overload will be cut, and the RCI screen will change the colour of the arrows
representing available hydraulic services from green to red for any service that has been motion cut.
Any hydraulic service that will result in the load moving to a safer position will still be allowed, and the
arrows on screen representing these services will stay green to signify that the services are still available.
Axle Lock
The machine
’
s Rated Capacity will generally be lower with the oscillating axle unlocked than when it is
locked. When working with a locked axle (static lift) and a lift and carry duty is required, the axle must be
unlocked. The RCI will monitor the Rated Capacity for both locked and unlocked duties, and if unlocking
the axle will put the machine into overload, the axle unlock signal will be interrupted by the RCI and the
axle will not be allowed to unlock. The axle lock symbol on screen will change to an unlocked padlock
with a red X through it, and the axle will remain locked until the load is moved to a position where the RCI
will not be in overload with the axle unlocked. At that point, the axle unlock interrupt will be released and
the axle will be allowed to unlock.
Travel Inhibit
The RCI will inhibit travel under the following conditions:
When the machine is in an overload state.
When the axle is locked.
When a height limit has been reached.
When the air pressure is detected as being low (air brakes).
