MIL-S-62095C(AT)

have a turned up lip not less than 50 mm (2 inches) high. The pickup plate shall extend sufficiently forward to protect the semitrailer from damage during coupling and uncoupling operations to and from a truck tractor. The pickup plate shall be integral with the upper fifth wheel plate.

* 3.11.3 Kingpin. A 50 mm (2-inch) diameter kingpin conforming to SAE J700 shall be furnished. The kingpin shall be fabricated of heat treated alloy steel.

* 3.12 Landing gear. The semitrailer shall have two vertical lift, telescopic, nonrotating, landing legs with two-speed gears, and a hand crank on the curbside. Landing legs shall be provided with self-leveling skid pads of not less than 250 mm by 250 mm (10 inch by 10 inch) square bearing area. A holder shall be provided for the hand crank when not in use. The landing gear shall withstand, without deformation, the combined static and dynamic forces due to the portion of the gross weight sustained, and the additional forces resulting from impact during coupling and uncoupling operations. When placed in the 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 functioning or mechanical efficiency. The semitrailer shall not nose over when resting on the landing gear.

* 3.12.1 Landing gear range of adjustment. The landing gear shall have a range of adjustment sufficient to vary the height of the upper fifth wheel plate at the kingpin from 1190 mm

(47 inches) to not less than 1320 mm (52 inches) from the ground for the size 2 semitrailer, and from 1190 mm (47 inches) to not less than 1370 mm (54 inches) from the ground for the size 4 semitrailer. The minimum ground clearance with the landing gear retracted shall be 280 mm

(11 inches).

* 3.12.2 Air/hydraulic powered landing gear. When specified (see 6.2), in addition to the requirements of 3.12 and 3.12.1 (less hand crank, etc.), the landing gear shall be air/hydraulic powered. The landing gear system shall include a control box equipped with a 12-volt dc motor driven pump, master control valve, leveling valve, booster, main oil tank, air side oil tank, key switch and mounting hardware.

* 3.13 Lighting. All lights and reflectors shall be protected from operational hazards by mounting in recessed or otherwise guarded locations. Lights and reflectors shall not be mounted on vertical surfaces of rub rails (unless recessed and fully protected) or on the semitrailer bumper. All electrical wiring shall conform to SAE J1292. Clearance and identification lights shall be constructed for easy removal and replacement of lamps and lenses without the use of any tools.

3.13.1 Twelve-volt direct current (dc) system. A 12-volt dc lighting system conforming to

3.13 and 3.13.2 shall be provided. The 12-volt dc lighting system shall conform to Federal Motor
