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

5.4.3 Fenders, mudflaps, and bumpers. Fenders, mudflaps, and bumpers shall not be provided for equipment unless they are essential for protecting the item being handled. For equipment used in UNREP, bumpers shall be provided for weapon protection.

5.4.4 Controls. All controls for energizing armament handling motions shall be designed on the dead-man principle. Handles, switches, etc., shall automatically neutralize in the absence of manual force.

5.4.5 Fuel servicing provisions.

5.4.5.1 Fuel tank construction and mounting. The fuel tank and filler neck shall be constructed to permit mounting in a location where damage from chafing against other equipment parts will not occur. Mounting attachments provided shall be of a type that will not loosen under operational vibration. When mounting straps are furnished, a barrier of fuel resistant material shall be provided to prevent chafing. The tank shall be vented to the outside of the enclosure and shall be able to accept fuel without spill back from a fueling nozzle or a fuel can. Spills or overflows shall be directed overboard without the possibility of trapping or pocketing in or on the enclosure. During refueling, the fuel delivery nozzle or container shall not come in contact with any exposed electrical components of the tank or equipment. Metal fuel tanks shall be metal to metal contact with the frame or incorporate a ground strap to frame permitting discharge of static electricity.

5.4.5.2 Fuel tank components. A cap, chain, filler neck, strainer, shutoff valve, and other necessary fittings shall be provided with each tank. The filler cap should be external to the enclosure to eliminate the necessity for an access door or plate. The cap shall be constructed of a material treated to resist corrosion, or a material inherently corrosion resistant. The cap shall be captive chained to the equipment. The chain shall not be connected to the fuel supply line, and shall be of sufficient size to inhibit loss of the fuel cap. The filler neck shall be constructed of materials treated to resist corrosion, compatible with the fuel tank, and affixed to the tank in a manner compatible with the type of tank construction. The filler strainer shall be removable, constructed of non-corrosive material, 60 mesh screen, and shall be protected to prevent damage caused by contact with the refueling nozzle.

5.4.5.3 Fuel tank marking. The type fuel and fuel tank capacity shall be stenciled on the equipment adjacent to the filler cap. Material used for marking shall be compatible with the type of fuel being used.

5.5 Requirements for non-mobile equipment.

5.5.1 Hoist cable guides. Hoists employing wire rope as the load carrying medium shall incorporate adequate guides, fairleads, and/or feed devices to prevent snarling or entanglement of cable during reeling operations.

5.5.2 Hydraulic lifting or hoisting mechanisms. Mechanical locking capabilities shall be provided on any hydraulic lifting or hoisting mechanism which is intended (or might be used) to hold the load in the raised or extended position for more than 2 minutes.

5.5.3 Positioning and stabilizing load. Where a load must be lifted into close quarters or onto precise mating, provisions shall be made for final adjustment in aligning, mounting, and stabilizing the load. This is especially important for shipboard operations where conditions of roll and pitch must be considered. When testing the complete unit for hoisting safety, these means should be locked out unless their failure would permit the load to fall. When systems handling equipment is operated through the trunk or hatch of a ship, guides shall be provided for lateral restraint when the operations will be conducted under conditions of more than 3 degrees of roll or list.

5.5.4 Hand operated hoist. Hand operated hoist(s) shall be designed such that, when the actuating force is removed, it will automatically stop and hold the load in the raised position.

5.6 Special requirements for boom-type hoists.

5.6.1 Classification of requirements. Hoists designed under this standard shall be subjected to all tests listed with the exception of those tests which do not apply to the hoist as designed (see 6.2). The hoist tests shall be classified as follows:

a. Product examination (see 5.6.2).

b. Functional requirement test (see 5.6.3).

c. Environmental requirement test (see 5.6.4).
