weapons assembly to lift a weapon from the handling
equipment or pallets to the assembly stands and from
the assembly stand to the handling equipment.
There are three basic types of hoists-manually
powered, electrically powered, and pneumatically
powered (fig. 11-14). A hoist maybe attached to the
overhead by a stationary fitting, or it may be mounted
onto an overhead monorail to move the load laterally.
You must use the correct sling, hoisting beam, and bomb
carrier when connecting the hoisting cable to the load.
Hoists have an established safe working load (SWL)
that you must consider when selecting a hoist for a
particular job. Also, consider the SWL of the interfacing
equipment (bomb carrier, sling, etc.). For example, you
have selected a hoist with an SWL of 4,000 pounds and
a bomb carrier with an SWL of 2,000 pounds. The
maximum weight this configuration can safely lift is
Inspect hoists before you use them, Hoist must be
periodically load tested. Equipment that has
satisfactorily passed periodic load tests is marked to
indicate its SWL. As a minimum, the marking includes
the following information:
The name of the testing activity and the name of
the person performing the test.
The date the test was performed
The date of the next required inspection maybe
included, if desired
If the test period has expired or if documentation is
not available to verify the latest load test status, the
equipment is tested before it is used. If the equipment
fails the load test specifications, the equipment is
destroyed or, if economically feasible, repaired.
There are currently more than 150 weapons
elevators, involving over 55 different designs, installed
on aircraft carriers. The size, type, and location of these
weapons elevators will vary among the different classes
of aircraft carriers.
The Forrestal-class carriers, the USS Kitty Hawk,
and USS Constellation have a combination of
5,500-pound, 2,000-pound, and 1,400-pound special
armament stowage space (SASS) and improved
weapons handling system (IWHS) elevators installed.
The USS Enterprise and USS America were
designed with pneumatically operated doors and
hatches. The elevators on the USS America include five
pneumatically operated elevators and three elevators
that have hydraulically operated hatches and
pneumatically operated doors.
The USS John F. Kennedy was designed with
platform conveyors and an athwartship shuttle. The
elevators have hydraulically operated doors and hatches
served from three power plants. Upper-stage elevators,
numbers 2, 3, and 4, are raised and lowered by hydraulic
ram instead of cables.
The elevators aboard the USS Nimitz have two
hydraulic power plants that serve 10 high-speed
elevators. All the doors and hatches are hydraulically
REVIEW NUMBER 2 ANSWERS TO QUESTIONS Q1. THROUGH Q7.
A1. Missile magazines are vented to the atmosphere.
A2. Mk 58 marine location markers shouldn't be stowed in magazines that are
equipped with sprinklers.

A4. Mk 3 Mk 12 metal pallets are used as magazine stowage dunnage aboard ship.
AS. All maximum and minimum readings taken from a magazine thermometer use the
bottom edge of the steel index marker as a reference.
A6. NAVAIRSYSCOM should be notified if the temperature in any magazine is
consistently above 100°F.
A7. The ship's gunner controls all magazine keys aboard ship.
