Functional AnalysisI
A method must be provided to lift and lower items to and from the radar tower,at the level of the base of the antenna pedestal. Items to be lifted includeLRUs in the antenna pedestal, supplies (e.g. oil), and tools and support testequipment. Most LRUs ine the antenna pedestal (e.g. motor, gear drive, etc.)are larger and/or heavier than can be carried tower (i.e. heavier than 10 poundsand/or bulkier than 0.5 cubic feet). Fixture (e.g. davit, tripod, boo~dwinch should be installed at the tower, inside of the radome. The fi.xtureshould be collapsible or lowerable so that is does not interfere with therotation of the antenna; does not make access to the pedestal more difficult.
Recommended Solution .-i -
1"" Develop a radar Tower Lifting Fixture for incorporation as a permanent installed
handling equipment in every NEXRAD radar tower. Includ~ common off the shelfhoist or winch capable of lifting approximatel~~lbs. from the ground to thetop of the highest NEXRAD radar tower at 30 meter~ Thern1s crane, MODEL 5128and winch, model 40218 and 40318 are recommended. They come with galvanizedsteel aircraft cable. See table below for breakout of parts. Themanufacturer's specification sheets are attached.

MARINE GRADE WINCHES
Marine spur g"ear winches are identical in size and rating tothe industrial models, but they have superior corrosionresisting features:
.Ali marine winches are painted with a primer base coatfollowed by an enamel finish coat. Excellent resistanceto sal~ spray corrosion.
.Stainless steel fasteners and springs.
.Oil impr~nated bronze bushings and seaJed ball bearings.
.Thern marine winches have been tested In accordancewith the prO.cedures of ~STM .Method B~ 17.73 Salt FogTest. .".,-",.-" -
NOTE: All Thern winches, when used for lifting, lowering orpulling on an incline, must be equipped with a Disc Brake.See Bulletin 40B. ".

is accommodated by installation of additional bases(model 511). '
.The two Econo Crane models convert easily from oneto the other simply by removing trom' one base andreplacing to the other base. (Example: from Davit base511 to Wheel base 514.)
NOTE: Final responsibility for detemlining suitability of equip-ment to any parucular use is that of the owner and/or user;thl'.. all a.,plicable codes, regulations. and manuals of materialhandling should be studied.
