MIL-H-18766, MILITARY SPECIFICATION: HYDRAULIC EQUIPMENT, ORDNANCE SHIPBOARD (GENERAL SPECIFICATION FOR) (24 JUN 1955) [NO S/S DOCUMENT]., This specification is intended to cover thegeneral requirements applicable to all hydraulic equipments forshipboard use under the technical control of the Bureau of Ordnance. Requirements and information which apply to individualequipments designed for specific purposes will be furnished inthe form of detail procurement specifications or will be includeddirectly in the procurement documents which are issuedwith invitations to bid. The requirements contained in thisspecification shall apply to shipboard ordnance hydraulicequipments when directly referred to in the detail procurementspecification of procurement documentsMIL-DTL-32266, DETAIL SPECIFICATION: WIRE ROPE, 1.5 INCH DIAMETER, GALVANIZED, COMPACTED STRAND, FOR AIRCRAFT ELEVATOR (08 JUN 2008)., This specification covers the requirements for 1.5 inch diameter, galvanized, compacted strand construction wire rope (see 6.4.8 and 6.4.9) used for Navy shipboard aircraft elevators. The wire rope must provide high tensile stiffness to minimize the changes in platform elevation associated with roll-on and roll-off of aircraft and a uniform density that provides consistent tension values in service. It must also provide good bending fatigue performance to accommodate repeated cycling over the various sheaves in the elevator system. The rope must be resistant to corrosion associated with continual exposure to and operation in a salt water environment.
