The control panel is a rectangular sheet of steel
mounted on the engine structure on the CRO-valve
side of the engine.
Three air manifolds are located on the control
panel: a
main air-charging manifold with
high-pressure air piping leading from the ship’s
high-pressure air supply system; an air manifold for
the auxiliary air flasks; and a manifold for the
accumulator.
The main air-charging manifold is
equipped with an air-charging valve, which is closed
except when taking on air from the ship’s
high-pressure air supply system to charge the
auxiliary air flasks and accumulator.
High-pressure air piping is provided from the
main air-charging manifold to the auxiliary air flask
manifold and the accumulator manifold.
The
auxiliary air flask and accumulator manifolds each
have air-charging valves, gauge valves, and a
pressure gauge. The auxiliary air flask charging
valve allows for charging the auxiliary air flasks or
emergency charging of the accumulator from the air
flasks.
The auxiliary air flask pressure gauge
monitors the air pressure of the auxiliary air flasks.
The accumulator charging valve allows for charging
of the accumulator and air expansion flask. The
accumulator pressure gauge monitors the air
pressure of the accumulator and air expansion flask.
A fuse switch box is mounted at the end of the
control panel and contains the main switches for
activating the electrical system of the arresting gear.
The cable anchor damper battery position
indicator light box on the control panel contains a
power ON and OFF switch and three indicator
lights. A white light indicates the power switch is
on. Two green lights give battery position indication
of the cable anchor dampers.
Cylinder and Ram Assemblies
The cylinder acts as a receiver for the ram and
as a reservoir for the fluid to be displaced by the
ram. Figure 3-13 illustrates the cylinder and ram
assemblies of the Mod 2 and Mod 3 arresting
engines.
