MIL-T-62735

(d) Pressure relief valve to prevent loading beyond lifting capacity.

(e) Devices to limit vertical creep of the boom to not more than 25 mm (one inch)

per hour.

(f) Signs with 25 mm (l-inch) lettering visible to the operator at both sets of controls: OUTRIGGERS MUST BE IN PLACE BEFORE LIFT IS MADE. Signs shall conform to 3.10.5.

(g) Full control identification and instructions in accordance with 3.10.5.

3.9 Military modification requirements. Military modifications shall be made in full compliance with the human engineering design criteria of MIL-STD-1472 and without compromise of any other requirement in this specification or the contract.

3.9.1 Brake lights and four-way flasher. At least one pair of brake lights shall override the four-way emergency flasher or the two systems shall be independent of each other. Modifications to the manufacturer's standard product to accommodate this requirement shall not compromise conformance to any FMVSS or FMCSR. On truck tractors, the brake lights need to override the four-way flasher only when coupled to a semitrailer.

3.9.2 Horizontal exhaust system fuel shield. All horizontal portions of the exhaust

system on truck tractors which project to the rear of the cab shall have a corrosion-resistant cover plate that forms a shield to shed fluids, preventing fuel spilled from a coupled semitrailer from coming into contact with the exhaust system.

3.9.3 Brake connection for towed vehicle brake control from a towing vehicle. When specified (see 6.2), vehicles with air brakes shall have a system for controlling its brakes from a towing vehicle (wrecker). The installation shall be complete with SAE J318 gladhand couplers, relay emergency valve with no-bleed-back feature (except when a spring applied emergency brake is furnished), additional air lines and fittings. See 3.9.

3.9.3.1 Gladhand couplers. The service and emergency couplers shall be on the front in a protected position providing for ready attachment of matching air hose couplers from a towing vehicle. Identification of the service and emergency couplers shall be in accordance with 3.10.5. The system shall have SAE J318 dummy gladhand couplers with security chains or cables.

3.9.4 Special fuel requirements. Diesel engines (see 3.3.2) shall demonstrate the performance characteristics specified herein when using diesel fuel conforming to VV-F-800. In addition, when specified (see 6.2), the engine(s) shall operate satisfactorily on grade JP-4 and grade JP-5 fuel conforming to MIL-T-5624 under emergency, short duration conditions and on grade JP-8 fuel conforming to MIL-T-83133 under normal conditions. A power loss when operating on JP-4, JP-5 or JP-8 is acceptable.
