7  Rated Capacity Controller 
7.1  Introduction 
PMERail has been designed to meet Network Rail requirements for the provision of rated 
capacity indicators and ensures that the maximum lifting capacity over the range of a ma-
chine working envelope can be utilised. The system will default to Lifting Mode when 
started up or when the bogies are deployed. See section 4 for operating advice when us-
ing construction plant as a crane. The blue lamp will indicate that Lifting Mode is active.  
The SWL as displayed assumes that 
the load is suspended directly below 
the lifting point. The weight of the 
tool or tools, if fitted, (e.g. Bucket , 
quick hitch etc) are included in the 
SWL and LOH values if they were 
taken into consideration when the 
system was calibrated. The bucket 
cylinder and control linkage is 
assumed to be present. 
Any alterations or modifications to 
machine components which affect the 
RCI must be reported to Prolec Ltd or 
via the machine convertor/service 
agreement holder.
