Stabilizer Manifold Assembly - Located on the A-Frame. Solenoid valves housed in

the Stabilizer Manifold Assembly when activated allow hydraulic fluid to operate the A-Frame

Folding Cylinders and the A-Frame Stabilizer Cylinders.

(8)

Roller Brakes and Back-up Mode Operation - The Roller Brakes and Back-up Mode

Operation control are mounted on the A-Frame Assembly. A constant hydraulic oil pressure

is felt at the Roller Brakes. The Back-up Mode Operation controls are mounted on the A-

Frame allows the A-Frame hydraulics to be operated in the event of remote control failure.

(9)

Launch Frame Pilot Manifold Assembly - Located on the right hand side of the

Launch Frame. A series of solenoid valves, when activated, allow hydraulic pressure to

assist in the operation of the Articulator Cylinders. Hydraulic pressure is also delivered to

the Pinch Roll/Stowing Manifold Assembly.

(10) Pinch Roll/Stowing Manifold Assembly - Located on the right hand side of the

Launch Frame. The Pinch Roll/Stowing Manifold Assembly allows hydraulic pressure

through solenoid valves to operate the Stowing Cylinders.

(11) Launch Frame Articulator Manifold And Synchronization Manifold - Located on the

left-hand side of the Launch Frame. Solenoid valves, when activated, allow the Articulator

Cylinders and the A-Frame Rotate Cylinders to be operated. Hydraulic pressure is also

delivered to the Launch Frame Winch Control.

(12) Launch Frame Winch Control Manifold - Located on the left-hand side of the Launch

Frame. The Launch Frame Winch Control Manifold houses a series of solenoid valves

which, when activated, allow the Upper and Lower winches to be operated. Hydraulic

pressure is also delivered to the Beam Drive Structure to allow operation of the Beam Drive

Motors.

LAUNCHER HYDRAULIC SCHEMATIC DRAWINGS

a. The hydraulic circuits are made up of four major service lines:

P-

Pressure

Hydraulic fluid at either working or a nominated pressure

T-

Tank

Hydraulic fluid fed back to the tank under pressure

D-

Drain

Hydraulic fluid returned to the Tank or a drain point

LS -

Load Sensing

Hydraulic fluid signals the hydraulic pump to either increase or

decrease pump pressure out put during operation of the launcher

LAUNCHER ELECTRICAL SYSTEM OVERVIEW

a. General Description - An electrical system provides power to switches and solenoids which,

when activated, allow the operator to control the function of the launcher components.

b. Electrical power is supplied from the host vehicle. Harnesses connect junction boxes,

switches and solenoids in the electrical system. Junction boxes redirect electrical supplies to

specific sub-systems.

c. Limit switches and indicators are fitted in the circuit to provide a signal, a visual indication at

the control panel, of the state of a component.

d. Solenoid valves, when activated electrically, will allow or stop the flow of hydraulic fluid in the

hydraulic circuits.
