SCOPE This CID covers
2、tire chain assemblies and replacement cross chains with cross chain hooks for use on military tactical wheeled vehicles equipped with military single pneumatic tires. Tire chain assemblies are referred to herein as “chain assemblies“. 1.1 Description. Each chain assembly is comprised of two side cha
3、ins and the required number of cross chains for each tire. Cross chain hooks are used to connect the cross chains to the side chains. Side chain fasteners are used to connect the ends of each side chain. Replacement cross chains are used to repair chain assemblies. 2. SALIENT CHARACTERISTICS 2.1 Mat
4、erials. All tire chain components shall be made of carbon steel, Unified Numbering System (UNS) grade G10060 through 610200, except for the cross chain hooks. The cross chain hooks shall be carbon steel, UNS grade G10120 through G10220, and shall be stress relieved after cold forming. The use of rec
5、overed materials made in compliance with regulatory requirements is acceptable providing that all requirements of this CID are met (see 5.5).
