OVERLOAD INSPECTION
This information supplements the Rated Capacity Limiter
(RCL) manual supplied with each National Crane.
When the RCL system has acknowledged an overload on
your crane, you must carry out specified inspections on the
crane.
These inspections apply only to overloads up to 50%. For
overloads of 50% or higher, crane operation must be
stopped immediately and Crane Care must be contacted for
corrective action.
T h e f o l l o w i n g i l l u s t r a t i o n s m a y n o t b e a n e x a c t
representation of your crane and are to be used for reference
only.
NOTE: If your crane is equipped with CraneSTAR, an
overload warning will be posted to the web site for
review by the crane owner.
Overload warnings do NOT indicate real time
events! Warnings could be sent 24 hours (or more)
after the actual event.
