MIL-S-62294B(AT)

* 3.13.2 Pickup plate. A turned up lip pickup plate, compatible with the size and weight of the

semitrailer, shall be provided as an extension of the upper fifth wheel plate. The pickup plate

shall have a turned up lip not less than 2 inches high. The pickup plate shall extend sufficiently

forward to protect the semitrailer from damage when coupling to and uncoupling from a truck

tractor. The pickup plate shall be integral with the upper fifth wheel plate.

* 3.13.3 Kingpin. A 2-inch diameter kingpin conforming to SAE J700 shall be furnished. The

kingpin shall be fabricated of heat treated alloy steel.

* 3.14 Landing gear. The semitrailer shall have two vertical lift, telescopic, nonrotating

landing legs, with two-speed gears and a handcrank on the curbside. The landing legs shall be

equipped with steel wheels or self-leveling skid pads. Supports for the crank extension shaft and

clips for holding the crank when folded shall be provided. The landing gear shall withstand,

without deformation, the combined static and dynamic forces due to the proportion of gross

weight sustained and the forces resulting from impact during coupling and uncoupling

operations. The landing gear assembly shall be mounted to plates that are gusseted to resist

forward and rearward dynamic thrust on the landing legs. When placed in travel position, the

landing gear legs shall remain positively locked. The landing gear shall be protected to prevent

the entrance of foreign matter which would impair its functional or mechanical efficiency. The

maximum cranking effort to raise the fully loaded semitrailer shall be not greater than

100 pounds.

* 3.14.1 Landing gear range of adjustment. The landing gear shall have a range of adjustment

sufficient to vary the height of the upper fifth wheel from 41 inches to not less than 53 inches

from the ground. With the semitrailer coupled to a towing tractor and in level position, the

clearance under the fully retracted landing gear shall exceed the semitrailer ground clearance, but

shall in no case be less than 11 inches.

* 3.15 Lubrication system. All moving parts normally requiring lubrication shall be provided

with accessible pressure grease fittings. Pressure type lubrication fittings shall be readily

accessible for servicing and shall conform to SAE J534. Pressure relief fittings shall be used

where high pressure lubricating-equipment could cause damage to seals.

* 3.16 Lighting. All lights and reflectors shall be protected from operational hazards by

mounting in recessed or otherwise guarded locations. The brake lights shall override the

four-way emergency flasher or the two systems shall be independent of each other. Lights and

reflectors shall not be mounted on vertical surfaces of the rub rails (unless recessed and fully

protected), or on the semitrailer bumper. Turn signal lamps shall conform to SAE J588. All

electrical wiring shall conform to SAE J1292. Clearance and identification lamps shall be

constructed for easy removal and replacement of lamps and lenses without the use of hand tools.
