The contract line item is CLIN 0001- UTILITY TRANSPORT TRAILER SYSTEM (5 EACH). This specification establishes the requirements for a utility transport trailer system consisting of a 20kW generator set and 96,000 BTU/hr environmental control unit (ECU) mounted on a steel frame trailer for use with the heavy High Mobility Multi-purpose Wheeled Vehicle (HMMWV). The 20kw generator set shall be equipped to provide power to the ECU and to shelters for lighting and other equipment. The generator shall have the capability of producing the required power at 120/208 VAC, three phase, five wire power with voltage regulation of +/- 2% from no-load to full load conditions at 105 degrees Centigrade generator rise. Frequency regulation under variable loads will be 5% from unloaded to fully loaded. The generator set shall be enclosed in a weather resistant, sound attenuated enclosure that shall attenuate sound to less than 80 dba at 3 feet from the control panel under full load, with removable service doors. The control panel shall be protected from the elements with a hinged (or equivalent) access door with a window. The trailer must be designed to carry 2 DHS DRASH Model 6 and 1 DHS DRASH Model 4 (rapidly deployable shelters and shelter accessories manufactured by DHS).

The trailer system shall be designed to meet basic mobility/transportability requirements as established by the US Army's Tank and Automotive Command (TACOM) and shall be fabricated to conform to established criteria for safe to transport by the Military Transport Management Command (MTMC) as suitable for secondary and unimproved roads. The trailer system shall be designed to meet MTMC standards for internal/external airlift, secondary/unimproved road mobility, and sea-lift transportability. The trailer system must be airlift-certified for internal aerial delivery by C-130, C-141, C-5 and C-17 aircraft. The trailer systems physical dimensions are as follows: Length- 230 inches maximum; Width- 86 inches maximum; Height-85 inches maximum, unloaded weight-not to exceed (NTE) 4,000 lbs; gross weight- (NTE) 6,000 lbs; wheel track-same as HMMWV; payload capacity-2,000 lbs; main cargo area capacity- 150 cubic feet minimum; main cargo shall be rear accessible; color/paint-finish coat per MIL-C-46168 over a primer system per MIL-P-53022; finish color shall be 383 green or 686 tan per FED-STD-595. The trailer shall conform to the following physical requirements-steel channel construction with a steel bed; air/sea transport lift/tiedown shackles (shackles positioned for helicopter lift using a spreader bar); 3-inch pintle hook lunette eye; hydraulic surge brake rated at 6,000 lbs with a 10,000 lb actuator and 2 safety chains; front pedestal jack; hand-operated parking brake; 6,000 lb rated TORFLEX axle with an axle to track a HMMWV; 36 inches x 12.5inches-16.5inches load rated C radial tires; two MS52125-2(24VDC) tail light assemblies and connected via a cable with an MS75020 12 pin plug to mate a HMMWV receptacle; tarp tie down hooks; (NTE) 6,000 lbs GVWR; ( NTE ) 750 lbs tongue weight when fully loaded; in-chassis fuel tank which will provide continuous operation of the generator set for a minimum of 12 hours without refueling and equipped with a fuel tank switch (trailer off auxiliary) to allow generator to be capable of operating from the in-chassis fuel tank or through an auxiliary feed to external source and fitted with a four inch diameter filler, a mechanical type fuel gauge, and suitable valves and plugs to allow fuel tank drain. The following ancillaries shall accompany the trailer system: one full size spare tire; hydraulic jack; lug wrench; a 5/8 inches diameter rod with drive stud and 3 bronze coupling with mounting provisions and on 10" AWG-8 ground wire for grounding the trailer; one 4 lb mallet or sledge hammer; one 5 lb ABC dry chemical fire extinguisher with mount; a weather proof trailer cover with eyelets and cordage to securely attach to the hooks provided on the periphery of the trailer; duct set- Four 12 inch diameter 25 foot insulated ducts that shall be used to provide air supply and return between the ECU and the shelter system. The generator shall consist of the following major components: (a) engine -: Lister-Petter Model LPWT4A9 engine equipped with a 12 quart capacity deep oil sump, valve cover fill, critical type exhaust silencer, thermal exhaust blankets on all exhaust items including manifolds, flexible connections, silencer, and pipes. The engine shall be fitted with valves for lubrication, oil drain, coolant drain and be equipped with a coolant recovery system, (b) electric generator- Marathon Model 282PSLI505, (c) generator control panel -- the generator set shall be equipped with three 3-wire wall mount receptacles to provide 120 VAC, single phase power for shelter lighting and other equipment. The output power available from the three wall mounted receptacles shall be circuit breaker protected at 20 amps. One 3 phase, 60 amp wall mount inlet connector, per MIL-C-22992, shall be installed at the generator power panel and shall be capable of accepting 60 amp, 3 phase 120/208 VAC shore power. Light indicators shall signal where power is available at each connection, (d) instrumentation panel -- The generator instrument panel shall consist of an AC ammeter, AC voltmeter, wattmeter and frequency meter. The engine instrumentation shall consist of a DC ammeter for the battery charging alternator, a DC ammeter for the battery charger, an oil pressure gauge, a coolant temperature gauge, and an hour meter. A control switch shall be provided for the engine with switches identified for Preheat/off/run/start.
