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

5.3.3.6 Design proof load. The loader shall withstand a design proof load (see table I) applied to the forks with the center of gravity (c.g.) of the load in a normal weapon or store position and held there for 5 minutes. Evidence

of yield in any of the components, which could in any manner prevent the loader from meeting operational requirements during service life, shall be reason to consider that the loader has failed this test. Due to the extreme

load it is recommended that one axle be blocked at the wheels and the opposite end of the loader be tied down.

5.3.3.7 Mobility.

5.3.3.7.1 Road. The loader(s) shall be subjected to a road test of 50 miles over paved level surfaces, 25 miles loaded (rated load) and 25 miles unloaded. At the end of this test there shall be no evidence of damage or construction deficiencies. During the 25-mile loaded portion, one short stop is permitted to cool down the loader if necessary. The duration of the stop should not exceed 30 minutes.

5.3.3.7.2 Side slope stability. The loader shall be required to demonstrate its ability to remain stable when driven sideways on an 8-percent (4.5-degree) grade. Loader side rails, if any, may be extended during this operation.

5.3.3.7.3 Brakes. The brake test requirements are as follows:

5.3.3.7.3.1 Service brake. The service brake shall be tested for its capability to hold the loader, fully loaded, without slippage on a dry, 20-percent (11.5-degree) grade for shore-based equipment or a 26-percent (15-degree) grade for shipboard equipment. All tests to be done with loader facing both up and down the grade.

5.3.3.7.3.2 Parking brake. The parking brake shall be capable of holding the vehicle motionless on the following slopes, up and down:

a. 20-percent (11.5-degree) slope with rated load for shore-based equipment. b. 26-percent (15-degree) slope with rated load for shipboard equipment.

5.3.3.7.3.3 Emergency braking. The service brake shall be applied in full force while the loader is traveling at top speed in a loaded condition. The brakes shall be capable of locking all four wheels in this test. Using a time distance recorder, the loader shall be brought to a complete stop from top speed within the distance specified in the applicable development specification after brake application. This test shall be repeated three times. Failure to pass any one of these tests shall be cause for rejection.

5.3.3.8 Ramp negotiation. The loader shall demonstrate its capability of climbing a 10-percent (5.7-degree) grade loaded or a 20-percent (11.5-degree) grade unloaded. No point on the loader other than the wheels shall contact the ground or the ramp. The loader shall negotiate this grade under its own power. Failure to do so shall be cause for rejection.

5.3.3.9 Creep capability. The loader shall demonstrate smooth acceleration from a dead stop to a constant slow speed. Any evidence of surging or leaping shall be cause for rejection.

5.3.3.10 Speed. The loader shall be tested at top speed and must be capable of attaining its designed speed as specified in the applicable development specification. Conformance with this requirement shall be ascertained by a test which shall be performed on a level, hard roadway. The loader shall be accelerated to its top speed which shall be maintained through a measured course of 400 feet. The average top speed shall be determined by measuring the time the loader takes to travel the 400-foot course. The test shall be conducted twice.

5.3.4 Environmental. The general requirements specified in MIL-STD-810, except as noted, shall apply to the environmental tests specified herein.

5.3.4.1 Temperature extremes.

5.3.4.1.1 High temperature. Unless otherwise specified in the applicable development specification or by the procuring activity (see 6.2), the equipment shall be tested in accordance with MIL-STD-810, Method 501.5, Procedure II. The following detail requirements shall apply:

a. Pre-test data shall be required.

b. High storage and operating temperature shall meet the requirements of 4.9.1.
