JUNCTION BOX

(1) JUNCTION BOX. The junction box,
located on the crane subframe,
receives power (24 volts DC) from the
FRS 24 VDC system. The junction box
is the center for all of the crane’s
electrical connections.
(2) OVERLOAD SHUTDOWN SYTEM
MICROPROCESSOR. The
microprocessor receives information
from four sensors to allow a comparison
of the actual load and rated load. If the
load is over the rated load, the
microprocessor will lock out all
functions that would increase the load
exerted on the crane. These are boom
up and down, hoist up, and telescope
out. All other functions are not affected
by the lockout signal.
