The elevating assembly consists of an elevating arm,
upon which a cradle assembly is mounted. The cradle
assembly consists of a tilting table and cradle. The
cradle is equipped with rollers for positioning the
weapon. The tilting table and cradle can be tilted 30
degrees forward or backward in a vertical plane by using
a hand wheel. The cradle can be adjusted in the
horizontal plane and rotated around its center with travel
fixed by the table lock plate. The cradle is also capable
of lateral movement. It can be rolled on table rollers
from side to side with travel fixed by the table. The
cradle movements are used to align and stabilize the
weapon during loading. The cradle is equipped with
tie-down straps to secure the load. Outriggers may also
be used to provide greater stability during weapon
elevation.
The front axle is steerable and equipped with a
drawbar, which has a towing eye on its end. The towing
eye is used to couple the trailer to a towing vehicle. A
pintle hook welded to the rear frame lets you couple it
with another trailer to form a train. Pad eyes are located
on the front and rear of the trailer for use with a safety
chain assembly provided with the trailer. The trailer is
equipped with a safety chain connected to the towing
vehicle. When multiple trailers form a train, the safety
chain is connected between trailers to prevent the
drawbar from dropping to the ground if a drawbar or
pintle hook fails. The trailer is also provided with a
static chain to ground static electricity. All Mods of the
trailers are equipped with a rear-wheel mechanical
parking brake.
Mk 7 Mods 3, 4, and 5 bomb trailers are used to
transport and load a variety of weapons and stores. For
transport, a towing vehicle is required, and more than
one trailer can be towed. The Mk 7 bomb trailer has an
SWL of 2,250 pounds.
For aircraft loading and
unloading operations, manpower is used to position the
trailer. Tow the trailer at a safe speed. Speed is
determined by the user activity; tow a single trailer with
a specified load at a speed not to exceed 15 miles per
hour. Tow multiple trailers in a train at a speed not to
exceed 5 miles per hour.
