MIL-STD-1365 General Design Criteria For Handling Equipment Associated With Weapons And Related ItemsThis design standard contains the general design criteria and applicable tests for beams, bands, strongbacks, cradles, assembly stands, slings, dollies, bomb loaders, trailers and hoists used as an integral component of an ordnance handling device associated with handling weapons and related items. This standard is not intended to be used directly for acquisition of related equipment, but is to be used as the basis to prepare appropriate development specifications from which the equipment is to be designed and procured.

MIL-STD-1365C

5.1.4.3 Brakes.

5.1.4.3.1 General requirements. All mobile equipment shall have brakes capable of restraining the handling equipment and its rated load on specified floor or deck conditions. For shore-based equipment, the service brakes shall be of the air-over-hydraulic or electric-hydraulic actuated type. For shipboard applications, mechanical brakes shall be used for skids and transporters, while loaders shall incorporate either mechanical or fluid as required. Except as specified herein, the brake requirements for all mobile equipment shall be in accordance with

SAE-AS8090.

5.1.4.3.2 Parking brakes. An automotive type manual parking brake shall be provided. The parking brake shall be capable of holding the equipment, loaded to rated capacity, stationary on an incline of 11.5 degrees. No rolling

or skidding shall take place. The force to fully actuate the parking brake shall not exceed 30 pounds if applied by hand or 50 pounds if applied by foot.

5.1.4.3.3 Service brakes. Automotive style service brakes shall be provided and shall be capable of holding the equipment, loaded to rated capacity, stationary on an incline of 11.5 degrees, and stopping the loaded vehicle from a speed of 20 mph when traveling on a dry, level, concrete surface in not more than 30 feet from the point at which the brakes are applied. Force required to operate the brake pedal and lock the brakes shall not exceed 80 pounds.

5.1.4.4 Examination and test conditions.

5.1.4.4.1 Environmental. Unless otherwise specified in the applicable development specification or by the procuring activity (see 6.2), the item shall be tested or examined under the following conditions and in accordance with MIL-STD-1366.

a. Temperature: 77±18 °F

b. Humidity (relative): 90 percent maximum c. Barometric pressure: Ambient

5.1.4.4.2 Item examination. The item shall be examined for conformance with applicable product specifications and drawings, with respect to performance functions. The product shall be operated with a load and shall demonstrate adherence to the design requirements. In addition, any part of the product which supports or encloses a weapon or component shall be checked to assure that proper contact is achieved between mating surfaces and that there is no slippage, binding or interference.

5.1.4.4.3 Functional.

5.1.4.4.3.1 Rated load. The product shall be tested for not less than 5 minutes carrying the rated load. Equipment not at rest on a horizontal flat surface shall be securely mounted to a stationary apparatus, so that minimal movement is made during testing. After application of the rated load, critical areas of the product shall be inspected to ensure that no overstressing of parts has resulted. In addition, the tests shall conform to the design requirements of 4.4 or as required by the applicable development specification.

5.2 Special requirements - trailers.

5.2.1 Classification of requirements. Trailers designed using this standard shall be subjected to all tests listed with the exception of those tests which do not apply to the trailer as designed (see 6.2). The trailer test requirements shall be classified as follows:

a. Product examination (see 5.2.2)

b. Functional requirement (see 5.2.3)

c. Environmental requirements (see 5.2.4)

Unless otherwise specified in the applicable development specification or by the procuring activity (see 6.2), all testing shall be conducted with rated load.

5.2.2 Product examination. Trailers shall be examined for conformance with applicable trailer specification and drawings, with respect to function and performance. The trailer shall be towed without a load and demonstrate forward and rear mobility including proper steering, brakes, and tow bar functions.
