A/M 32K-4A SATS ROUGH TERRAIN TRAILER

The A/M 32K-4A SATS rough terrain trailer (fig. 9-60) is a transport vehicle that consists of a chassis and a lightweight, flatbed, aluminum body. The chassis has two axles and four single wheels that are equipped with pneumatic tires. A torque box provides strength and rigidity to the body. You can remove two sections of the

nonskid flatbed to use a forklift truck to load and unload the trailer. The trailer is equipped with a tow bar, multiple leaf springs, service brakes, and parking brakes. The trailer has 12 cradle tie-down fittings to hold the weapon cradles securely on the bed.

The A/M 32K-4A SATS rough terrain trailer is used to transport air-launched weapons from an ammunition dump to a SATS airstrip. You can operate it over very rough terrain. It is normally used at advanced bases.

The trailer holds weapons in cradles that are two tiers in height when equipped with increased load-density weapon cradles. The cradles are secured to the trailer bed by quick-release, positive-locking clips. The SATS trailer can also be equipped with stake sides and used as a utility vehicle for transporting weapon components. The A/M 32K-4A has an SWL of 8,000 pounds.

AERO 51C MUNITIONS TRAILER

The Aero 51C munitions trailer (fig. 9-61) is a transport vehicle that has an automotive chassis and a flat-deck body. The chassis has two axles and four single wheels equipped with pneumatic tires. The center section of the nonskid flat deck is hinged. It can be opened to provide a hatchway across the full width of the vehicle. It also has hinged deck panels that have double rails with holes at intervals to provide a mounting base for cradles and adapters.

The trailer has hydraulic surge brakes and mechanical parking brakes, a tow bar, and cable harness. The cable harness electrically connects the trailer to the towing vehicle for operation of the trailer lights. Accessory items (chocks, tie-down straps, interconnecting electrical harness, etc.) are stored in toolboxes mounted underneath the forward and aft decks.

The Aero 51C munitions trailer is used with a towing vehicle to transport and hold a variety of weapons in ready storage. The weapons are supported

on the trailer by adapters or cradles. This trailer is used to transport stores and cargo. The Aero 51C munitions trailer is not used aboard ship. The Aero 51C has an SWL of 8,500 pounds.

LOADERS

LEARNING OBJECTIVE: Identify the purpose and use of the SATS weapon loader, the Aero 47A, 47A-1, and MJ-7 weapon loaders.

Loaders are generally used to handle a variety of loads, such as weapons, ammunition, JATO bottles, rockets, pylons, or fuel tanks, during naval aircraft

loading operations. Some loaders are capable of operating over rough terrain while others are built for smooth surfaces. The types of loaders used to handle ammunition and explosives are equipped with flameand spark-arresting mufflers.

A/S 32K-1A/1B/1C SATS WEAPON LOADERS

Each A/S 32K-1A/1B/1C SATS weaponloader(fig. 9-62) is a self-propelled vehicle with a low, heavy-duty frame supported by six small, high capacity wheels. Each vehicle has two main functional components. The lifting mechanism has a lift boom, hydraulic system, and manipulating head. The lift boom is operated by a piston-type hydraulic cylinder mounted in the midsection of the boom support. The manipulating head is located at the upper end of the lift boom, and is capable of limited lateral and longitudinal motions, as well as tilting and yawing motions. The head is equipped with lifting forks attached with quick-release pins and mounted in three positions-normal, inverted forward, and inverted rear.

The drive mechanism includes a hydrostatic drive system powered by a power-splitter gearbox, drive shaft with universal joints, limited-slip differential, axle/wheel disconnect hubs, and steerable drive wheels with power-assisted steering.

The power to operate the lift and drive mechanisms is supplied by a four-cylinder, air-cooled gasoline engine. The weapon loader is equipped with four-wheel hydraulic brakes, electric/hydraulic operated parking brakes, and a spark- and flame-arresting muffler. It is also equipped with nylon tie-down straps to hold the load securely during handling, a utility chain to lift items

directly off the ground, and lights for night loading operations.

Each A/S 32K-1A/1B/1C SATS weapon loader has an SWL of 4,500 pounds. It is used to load externally carried munitions, weapons, and stores onto an aircraft. Each SATS weapon loader is used with a variety of adapters and cradles.
