TM 55-1945-205-10-20006 00 10006 00OPERATOR MAINTENANCEROLL-ON/ROLL-OFF DISCHARGE FACILITYTHEORY OF OPERATIONSYSTEM OPERATIONThe roll-on/roll-off discharge facility (RRDF) is a floating discharge platform for ocean-going roll-on/roll-off sealift vessels. The modules and equipment comprising the RRDF are pre-positioned aboard ship until needed to support combat operations. The RRDF is used in support of joint logistics over the shore (J-LOTS) operations. Vehicles are driven from the ship onto the RRDF and loaded on Army lighterage for transport to a theater of operations. The structure of the RRDF will withstand the cargo loading through Sea State 2 conditions.10 KW OR 15 KW SKID MOUNTED TACTICAL QUIET GENERATOR Refer to TM 9-6115-642-10 for the theory of operation of the 10 KW diesel generator set.Refer to TM 9-6115-643-10 for the theory of operation of the 15 KW diesel generator set.PERSONNEL SHELTERThe personnel shelter is contained in a 20 ft ISO container. Power is supplied to the shelter from the tactical quiet generator through a power cable stored in the shelter and connected from a 100 amp connector on the backside of the shelter to a 100 amp connector on the generator. The power provided by the generator supplies power to the electrical distribution panel, which is cabled to the incinerator toilet, heating and cooling unit, lighting, fire suppression system and to the GFI receptacles in the personnel shelter.6 KW TRAILER MOUNTED LIGHT TOWERThe lighting system consists primarily of a self-contained, trailer mounted, 6 KW diesel generator which illuminates the work area using four high pressure sodium 1000 watt lamps. The power to each lamp is controlled by individual switches on a control panel. The power is received from a 120 VAC - two phase alternator which is cabled through two 25 amp circuit breakers, to the switches, to a ballast box and connected by quick disconnects to the lights.VHF/FM HANDHELD TRANSCEIVERThe VHF/FM handheld transceivers are utilized for communicating between personnel during loading and unloading operations on the RRDF. The transceiver has a frequency range of 156.025 to 163.275 mhz, plus 10 weather channels. The transceiver has an RF power output with the CNB350 battery of 5.0 watts (high) and 1.0 watts (low). The operating voltage is 7.2 V DC. Current drain in standby mode is 40 ma, in receive mode 200 ma, in the transmit mode 1.8 amps (high power) and 0.7 amps (low power). The battery life (5% Tx, 5% rcv, 90% standby) is approximately 10 hrs (high mode) and 15 hrs (low mode). The audio response is within +2/-8 of 6 dB/octave pre-emphasischaracteristic from 300 hz to 3000 hz. The AF harmonic distortion of the transmitter is 3%. The transmitter has a hum and noise rating of 37 dB and a frequency stability (-20 Deg to +50 Deg C) of +/- 0.0005%. The receiver has a sensitivity rating of 20 dB, quieting at 0.35 uv and 12 dB SINAD at 0.30 uv. The squelch sensitivity (threshold) is 0.20 uv. Modulation acceptance bandwidth is + 4.5 khz. INCINERATOR TOILETRefer to TM 55-1925-257-14&P for the theory of operation of the incinerator toilet.
