ABSTRACT
This specification covers the general requirements for the Type III cargo bed cover (CBC). The Type III cargo bed cover is a removable general purpose rigid enclosure for the cargo bed of the 2-1/2 ton cargo truck (M35A2), 2-1/2 ton lightweight medium tactical vehicle (LMTV; M1078), and 2-1/2 ton LMTV trailer (M1082). The CBC provides environmental protection and security for mission equipment and items of general transport.
SCOPE
1.1 This specification covers the general requirements for the Type III Cargo Bed Cover (CBC). The Type III Cargo Bed Cover is a removable general purpose rigid enclosure for the cargo bed of the M35A2, 21/2 Ton Cargo Truck/M1078, 2 1/2 Ton Lightweight Medium Tactical Vehicle (LMTV)/M1082, 2 1/2 Ton LMTV Trailer. The CBC provides environmental protection and security for mission equipment and items of general transport.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parenthesis are for information only.
The following safety hazards caveat pertains only to the test required portion, Section 4, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
