TEREX’S entire range of RO Stinger boom trucks are now being fitted with rated capacity indicators (RCIs) as standard. Greer has been selected as sole supplier.
The Greer 500R system comes with a new display, which it calls the 586, giving the operator information to verify that he/she is operating safely. Load, radius, boom length, and capacity at current position are all available to the operator.
A three colour bar graph shows the percentage of maximum permitted load. Boom/jib configurations, and parts of line are described ‘in plain English’, Greer says, on the two-line LCD information screen.
This RCI will now be fitted on every Terex boom truck, from the model 7077 (rated at 35 US ton) down to the 2057 (10 US ton) at no extra cost to the customer, it is claimed. Previously RCIs were standard only on cranes above 20 ton capacity. Smaller models used less sophisticated electronic capacity alerts (called hydraulic capacity alert systems by other manufacturers), but this type of system does not protect the jib.
The Greer RCI system and/or 586 display are also available for retrofit onto most Stinger cranes made since 1989.
RCI is the accepted ISO term for what many still call a load moment indicator (LMI).
