TM 55-1945-205-10-40002 00 40002 00The light tower is a three-section telescoping mast which extends from 12 ft to 30 ft and has a rotation range of 360°with a position lock. The mast is easily extended with dual hand-operated winches that incorporate an automaticsafety brake. The tower retracts and stows horizontally for travel.The light system comes with a 30-gallon translucent polyethylene fuel tank, single point lifting bail, forklift slots,heavy-duty outriggers, leveling indicator and removable drawbar. The control panel comes with one GFI protected120 volts 20 amp duplex receptacle, one 240 volts 25 amp receptacle, individual lamp switches, and a non-resettablehour meter to track records for periodic maintenance.The overall length is (in./cm) 174/442, width is (in./cm) 79/201, height is (in./cm) 89/226 (travel position), standardtower height is (ft/m) 30/9 and shipping weight is (lb/kg) 2010/912.LIFELINE SUBSYSTEMThe lifeline subsystem is installed along the causeway sides and trident pierhead sides and shoreward end to protectpersonnel from falls overboard. The stanchions for the lifelines are installed in the turn-tube fittings and ISO cornerfittings of the section modules. The lifelines, life rings, nylon rope and strobe lights are installed on the inboard sideof the lifeline stanchion. Chain is used to span the gap between the sections. Lifeline arrangement may varydepending on FC configuration.COMMUNICATIONS EQUIPMENTThe communications equipment consists of four HX350S VHF/FM handheld transceivers. The transceivers have afrequency range of 156.025 to 163.275 mhz. All channels currently allocated in the USA, Canadian and Internationalchannels are available for use, plus ten weather channels.The HX350S has an RF power output with the CNB350 battery of 5.0 watts (high) and 1.0 watts (low). The operatingvoltage is 7.2 volts DC. The current drain in standby mode is 40 ma, in receive mode 200 ma, in the transmit mode1.8 amps (high power) and 0.7 amps (low power). The battery life (5% Tx, 5% rcv, 90% standby) is approximately10 hrs (high) and 15 hrs (low).The dimensions of the unit are 5.51 in. X 2.17 in. X 1.50 in. The weight is 1.0 lb.The transmitter has a conducted spurious emissions of 65 dB (high) and 55 dB (low). The Audio Response (AR) iswithin +2/-8 of 6 dB/octave pre-emphasis characteristic from 300 hz to 3000 hz. The AF Harmonic Distortion of thetransmitter is 3%. The transmitter has a hum and noise rating of 37 dB and a frequency stability (-20°C to+50°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. Receiver selectivity: spurious and imagerejection 60 dB, inter modulation regulation 60 dB and channel spacing 25 khz selectivity.DECK MATTINGThe deck matting is used as dunnage and is placed where the cargo ramps of the sealift vessel and the lighters willland on the FC deck. The individual mats are a high density polyethylene material and are approximately 10 ft longby 4 ft wide and 1½ in. thick. Each mat weighs 300 lbs.DECK CLEAT AND D-RING/CLOVER LEAF FITTINGSThe modular sections are provided with deck fittings to meet various operational needs. These fittings have a15,000 lb load capacity and are inserted into the tube turns. There are ten tube turns per non-powered module and fiveper end rake.
