Materials shall be free from any defects and imper- fections that may affect the serviceability or appearance of the finished product. Materials shall be in accordance with the requirements specified h

23、erein. Materials not definitely specified shall be of a quality to meet the requirements specified herein. 3.1.2 Recovered materials. Unless otherwise specified herein, all equipment, material, and articlis incorporated in the products covered by this specification shall be new and shall be fabricat

24、ed using materials produced from recovered materials to the maximum extent practicable without jeopardizing the intended use. The term “recovered materials“ means materials which have been collected or recovered from solid waste and reprocessed to become a source of rau materials, as opposed to virg

25、in raw materials. None of the above shall be interpreted to mean that the use of used or rebuilt products is allowed under this specification unless other- wise specifically specified. 3.1.3 Magnesium. Magnesium or magnesium base alloys shall not be used in shipboard equipment. 3.1.4 Brittle materia

26、l. Brittle material is defined as material showing less than 10 percent elongation in gage length during tensile testing. 3.1.4.1 Cast iron in any form shall not be used except where per- mitted by referenced specifications. The use of cast iron is limited to ASTM A 48, class 35, or better. Cast nod

27、ular graphitic iron or malleable iron conforming to MIL-1-24137 is acceptable for machinery equipment components. 3.1.4.2 Other britt!-? :qriis shall be used only where it is satisfactory to the COP -,;ing activity for a particular application. 3.1.5 Aluminua -,elded aluminum 6061-T6, ZXXX, and 7XXX

28、 material shall not be used f;- any parts. Aluminum castings shall be in accordance with QQ-A-601. 3.1.6 Metals. Metals that are usually considered to be susceptible to general corrosion attack by a sea water environment shall be processed (treated, plated, or painted) to provide corrosion resistanc

29、e. In order to minimize corrosion attack due to electrolytic action between dissimilar metals in contact with each other, metal-to-metal contacts shall be limited to those metals which, when coupled, are designated by an open square, an open triangle, or an open triangle with a cross bar, as shown i

30、n the table titled “Sea Water Corrosion of Galvanic Couples“ of MIL-E-917 under the following conditions: (a) For combinations of metals subject -to immersion, splashing, or spray from seawater, condition S; E, or L, as applicable, shall apply. 4 Provided by IHSNot for ResaleNo reproduction or netwo

If a metal is coated or plated, the metal rather than th

32、e base metal shall be considered. Metal-to-metal contact is considered to exist between parts that depend upon painting for corrosion resistance. 3.1.7 Prohibited materials. Cadmium plating or asbestos (except for brakes) in any form shall not be used. 3.2 General design. Hoist design shall provide

33、for required selec- tion of material, component design, and assembly tolerances to insure a hoist service life (minimum of 3000 cycles) which does not require any corrective maintenance actions. Rotating shafts shall be supported in anti- friction, lubricated, or self-lubricated bearings or bushings

34、. Shaft bushings or bearings shall be enclosed against entry of dirt, dust, or foreign material. Rotating and sliding surfaces shall be lubricated with lubricant in accordance with DOD-G-24508. Hoists shall operate at environ- ment temperatures of minus 20 degrees Fahrenheit (OF) through 130F. Gears

35、 shall be enclosed against dirt, dust, and water spray, in a casing that will permit ready access for examination and cleaning. Positive means of securing loose parts such as nuts, bolts, collars, and check rings within the casing shall be provided to prevent any component from working loose. Hoists

36、 shall be complete in all respects, including operating controls and other equipment that may be necessary for operation. Maximum combined stress in component parts shall not exceed 35 percent of the tensile yield strength of the material for hoist operation at rated capacity. Combined stresses in C

37、omponent parts shall not exceed 70 percent of its tensile yield strength, when the hoist is subjected to static or dynamic overload tests. For hoists requiring repair parts, sll wear parts shall be readily accessible for replacement. Component parts for the same type hoists from the same manufacture

38、r shall be interchangeable to the greatest extent possible. For hoist operation, a pull of not more than 1 pound per 200 pounds of total hoist load shall be exerted to initiate movement, and not more than 1 pound per 300 pounds of total hoist load shall be required for manual operation of the trolle

39、y. 3.2.1 Load chain. Hoist load chain shall be manufactured from an alloy steel electric or forge welded. Each chain link shall be of uniform size and shape and shall seat properly in the hoist chain sheave pockets. The chain shall provide a safety factor of at least 5 for the rated load based on th

40、e ultimate strength of the material. When specified (see 6.2.11, the chain shall be protected from corrosion by zinc plating in accordance with ASTM B 633, type II, class Fe/Zn 25. 3.2.2 Wire rope. Wire rope, where used for load lifting, shall be in accordance with RR-W-410. Wire rope shall provide

41、a safety factor of at least 5 for the rated load based on the minimum breaking strength of the wire. 3.2.3 Load chain wheels. Load chain wheels shall be provided with at least four pockets accurately shaped to fit the-links of the load chain, which shall operate freely and smoothly over the load whe

42、el. Guides shall 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-H-15317C 37 7979906 0281b77 T M MIL-H-15317C be provided to assure that the chain enters the chain wheel in proper position. These guides, if bolted on, shall have locknuts or oth

43、er means to prevent loosening under vibration. Load shaft may be integral with or rigidly connected to the load chain wheel. Welding of the wheel to the shaft is not acceptable. 3.2.4 Rope drums. Rope drums shall have machined cut grooves and rounded corners. Drum grooves shall have minimum depth eq

44、ual to 40 percent of the wire rope diameter. Drums shall be fitted on each end with recessed flanges to prevent rope jamming. Drum diameter shall be not less than 20 times the diameter of the wire rope, except when extra flexible rope is used and the diameter of the drum may be 15 times the diameter

45、 of the rope. There shall be at least one and one-half full turns of rope remaining on the drum with the hook in the lowest elevation of the rated list. The wire rope shall be secured to the inside of the winding drums with sockets or dead-end clamps. The wire rope de.ad-end connection shall support

46、 80 percent of hoist rated load. Drums, except those for type V hoists, shall have a rope winding guide and shall be protected both on top and side. 3.2.5 Load hooks. Load hooks shall be of drop forged heat-treated steel, and capable of withstanding the tests specified in section 4. Hooks shall conf

47、orm to those shown on figure 1 as specified (see 6.2.1). and shall be fitted with a safety device, and except for the fixed eye, regular, a swivel. The safety device shall consist of a spring latch or swivel type closure, to bridge the throat opening, and shall be an integral part of the hook. Swive

48、l shall permit 360 degree rotation of the hook with full load, without twisting the attached rope or chain. Hook throat openings shall be in accordance with the dimensions shown in table I.
