INTERNAL RATED CAPACITY LIMITER
LIGHT BAR
The Rated Capacity Limiter (RCL) Internal Light Bar
(Figure 3-15) is located at the upper left corner of the crane
cab.
The RCL Internal Light Bar is an operational aid that works
with the RCL system to warn the operator of an approaching
overload condition that could cause equipment damage,
personal injury, or death.
The lights in the light bar come on in the following manner:
• Green LEDs – when the eight green LEDs are on, the
load being lifted is less than 90% of crane RCL
programmed capacity.
• Yellow LEDs – when the yellow LEDs are on, the load
being lifted is between 90% to 100% of crane RCL
programmed capacity.
• Red LEDs -– when red LEDs are on, the load being lifted
is greater than 100% of crane RCL programmed
capacity.
