DESCRIPTION AND DATA
a. General. The FRS crane can be extended
to a maximum length of 18 feet. The crane is
capable of lifting 10,000 lbs. at 14 feet.
Beyond that, the crane is limited to lighter
loads by an overload shutdown system. The
crane can be rotated 300 degrees. The crane
is equipped with remote control functions. In
the event of electrical failure, or a hydraulic
failure the crane can still be stowed using the
manual override valve for the electrical failure
or the slave hose for the hydraulic failure.
b. Electrical System. The crane’s electrical
system operates on 24 volts DC, supplied from
FRS 24 VDC system. Electricity provides
power for the remote control system.
Electricity also controls the overload shutdown
system.
