The pump speed-control valves have three
positions-fast, medium, and slow. The speed-control
valve lets the operator adjust the flow of hydraulic fluid
from the manual pumps in proportion to the weight of
the load-fast for light loads and slow for heavy loads.
Set both the left- and right-hand speed controls at the

LEARNING OBJECTIVE: Identify trailers
used for ordnance handling to include the Mk 7
and Mods bomb, small munitions, SATS rough
terrain, and Aero 51C munitions trailers.
A trailer is a transport vehicle towed by another
vehicle, such as a truck or tractor. All trailers are
equipped with load-supporting bodies or frames and
with wheels for locomotion. Trailers may be divided
into three categoriesweapon trailers, weight handling
trailers, and warehouse trailers. Only trailers within the
weapon trailer category are discussed in this TRAMAN
because they directly support aircraft weapon loading
A weapon trailer consists of a heavy channel or
tubular frame mounted on two axles and wheels that are
equipped with four pneumatic tires. The frame is
supported by automotive leaf-type springs. The front
axle is steerable and the rear axle is fixed The trailer is
equipped with a tow bar or tow handle that has a towing
eye on its end. Use the towing eye to couple the trailer
to the towing vehicle. Some trailers have draw heads at
the rear to couple the towing eye of another trailer.
A weapon trailer has cradles or brackets that fit the
contours of the weapon being transported The cradles
or brackets on the trailer can be removed or adjusted for
carrying loads of various sizes. Hold-down devices,
such as chains or straps, secure the load during transport.
Some weapon trailers have hydraulic systems to load
weapons on aircraft, or for similar uses.
Weapon trailers are used to transport weapons, such
as bombs, mines, missiles, and torpedoes of various
sizes. In general, the trailers are capable of operating
over moderately soft or moderately rough terrain. The
short airfield tactical site (SATS) trailers operate over
very rough terrain. These trailers are towed by vehicles
such as the cargo truck (pickup). When coupled
together, the SATS trailers form a train behind the truck.
Dont use more than four trailers in one train.
MK 7 AND MODS BOMB TRAILER
The Mk 7 Mods 3, 4, and 5 bomb trailers (fig. 9-58)
are made of a low-slung, heavy, channel steel frame
mounted on four wheels. The trailers have a hydraulic
elevating system actuated by a manually operated pump.
