2.1 ~RAWL~R/TRANSP5RTER K/T)2.1.1 FUNCTION. The C/T (Figure 2-l) is used to transport the Launch UmbilicalTower (LUTI and the Mobile Service Structure (MSS). The CUT, including the spacevehicle, is transported from the Vehicle Assembly Buildinp rVAi3 to the launch pad.The MSS is transported from its parking area to and from the Launch pad. After launch,the LUT is transported to the refurbishment area and sul .quently back to the VAB.(See paragraph 2.1, Volume Il.1The C/T is capable of lifting, transporting, and lowering the LUT or the MSS, as re-quired, withod the aid of auxiliary equipment. The C/T suppiies limited electric powerto the LUT and the MSS during transit.2.X.2 5ES~R~~T~O~~ The C/T consists of a rectangular chassis which is supportedthrough a suspension system by four dual-tread crawler-trucks. The overall length is131 feet and.the overall width is 114 feet. The unit weighs approximately 6 millionpounds.The C/T is powered by self-contained, diesel electric generator units, Electric motorsin the crawler trucks propel the vehicle, Electric motor-driven pumps provide hydraulicpower for steering and suspension control. Air-conditioning and ventilation are providedwhere required.The C/T can be operated with equal facility in either direction. Control cabs are loca-ted at each end and their control function depends on the direction of travel. Theleading cab, irt the direction of travel, will have complete control of the vehicle. Therear cab will ( however, have override controls for the rear trucks only.Maximum C/T unloaded speed is 2 mph, 1 mph with full load on level grade, and 5.5mph with full load on a five percent grade. (It is capabie of accelerating a maximum of2.58 feet per second.1 It has a SOO-foot minimum turning radius and can positionthe LUT or.the MSS on the facility support pedestals within 2 two inches.2.1.2.1 Chassis. - The C/T dhassis is a rigid steel framework approximately 130feet by 90 -rests on four crawler-trucks and supports the LUT or the MSS aswell as housing the engines, generators, and all other auxiliary equipment.

conditions: summer - 95 degrees FBB, 79 degrees FWB; winter - 35 degrees F.Fueling onerations at the launch area require that the compartments within the structurebe pressurized to three inches of water and that the supply air originate from a remotearea free of contamination. Chilled water is supplied to the LUT at the VAB and thepad, from a remote area free of contamination, to provide cooling. There is one pack-aged air-conditioner which serves the areas requiring environmental control duringtransit. The computer room is maintained at 76-l-2 degrees FIX, and 45 percent rela-tive humidity (RH) +-5 percent at all times excepTduring LUT transit.-The primary electrica power supplied to the LUT is divided into four separate servicesas follows:

a. Instrumentation power.b. Industrial power.c. In-transit power.d. Emergency power,fnstrumentation and industrial power are supplied to the LUT at 13.8 kv. These powersystems are separate and distinct, Power is supplied from the C/T to a limited numberof items during LUT transit from the VAB to the pad. This power is used for the water/glycol systems, computer air-conditioning, threshold lighting, and obstruction lights.The emergency power for the LUT is from an engine generator located in the groundfacilities. it is used for obstruction lights, emergency lighting, and for one towerelevator,Water is supplied to the LUT at the VAB and pad for fire, industrial and domestic pur-poses, and at the refurbishment area for domestic purposes.2.3 HOMETOWN ARMS (SYSTEM NO. 041)2.3.1 FUNCTION. The basic function of the four holddown arms, which are locatedon the LUT deck (level O), is to position, support, and restrain the vehicle on thelaunch pad during checkout at the VAB, transportation to LC-39, and subsequent launchof the vehicle.

2.3.2 DESCRIPTION. Each of the four holddown arms (Figure 2-81 is identical andis located between each of the four outboard engines of the S-K stage. Each arm isapproximately 6 feet by 12 feet at the base and weighs approximately 37,000 pounds.Holddown is accomplished by a preloaded toggle linkage that applies the holddown forceto the vehicle thrust frame. The preload prevents separation of the vehicle and theholddown arm anvil during thrust build-up and minimizes the dynamic loads imposed onthe LUT structure at cutoff. Wind loads, engine misalignment, shock, and vibrationare considered in the design of the structure, Each support and holddown arm containsa spherical compression block for load transmission. Level adjustment is accomplishedby various shim thicknesses.


36/1242-3.4


37/124

Simultaneous release of the holddown arms is controlled by a Launch Commit signal[this is received after receipt of the thrust OK signal from thrust sensing devices),which in turn, controls the holddown arms release control panel. The holddown armsrelease control panef, an command, directs high-pressure helium (He) to each holddownarm assembly activating the pneumatic ball-lack separator, separating the toggle linkageand thus releasing the holddown arms.2.4 SERVICE ARMS ISYSTEM NO. c121)2 -4.1 FUNCTION. The nine service arms (Figure 2-9) provide access to the launchvehicle and support the SewiGe lines that are required to sustain the vehicle at the siteprior to launch.2,4.2 GENERAL ~~SCRI~TI~N. Each complete structural assembly consists oftwo or three elements of truss-type construction employing tubular members and gussetplates. The arms, excluding the Ccmmand nodule KMI access arm, are secured tothe LUT by two standard t~wer~m~unted hinges containing the arm retraction mechanism.3% CM access arm is secured to the tower by two large hinge plates which provide therequired rigidity between the tower and &n (Figures 2-10 throtigh 2-W.The service arms, excluding the CM access S-U aft arm, support the service linesthat link the vehicle to the ground supply and control system. The preflight arms C+ICintettank, S-X fom!ard, and S-Ii aft3 are retracted at P-14 seconds and secured tothe LUT by a latch-back mechanism. The inflight arms retraction system is actuatedby liftoff switches Iaated on the holddown arms.The CM access arm provides an environmentally conditioned means of astronaut ingressand,egress to the Apollo spacecraft. The arm is .retracted at T-6 seconds and hasthe capability of being re-e&ended within 30 seconds.2,4.2.1 Arm Retraction. Each arm is retracted by rotation of the arm after discon-nection oft rier from the vehicle. ..2.4.2.2 Umbilical Carrier Withdrawn. All carriers, except the S-K intertankcarrier arm, are pneumatically dis~~n~e~t~d from the vehicle by applying gaseous nitro=gea EN21 at 755 psi to the locking mechanism and push-off pistons located within thecarrier housing. Since the S-K intertank carrier contains Pnly two mechanical lines,dis~~nne~ti~n is achieved through the locking me~banism in lieu of the push-off pistons.The inflight arms, excluding the Service Module CS?vTI rm, utilize a dual-cylinder with-drawal mechanism in conjunction with the pneumatic disconnection of the umbilicalcarrier from the vehicle. The withdrawal mechanism is mounted on the vehicle end ofthe arm and is bolted to the umbili~ai.~arrier which contains the various service lines.

2.4.2.4 Access Platform. Service arm extension platforms, located at the vehicleend of the second element, provide access to the vehicle and umbilical area. Thesecond element contains brackets for supporting the extension platform box beam, whichis composed of a bearing carrier assembly consisting of recirculating roller bearingsmounted on a T shaped carrier, In areas :vhere the horizontal vehicle deflectionsexceed four inches, a T head is located at the end of the extension pl~qtform, TheT head moves perpendicu!ar to the basic platforms on rollers to accommodata vehiclemotion in the lateral direction. The basic platform utilizing the T head (S-II forward,S-IVB aft, S-IVB forward, and SM arms1 is connected to the vehicle through a couplermounted on the IT head bumper assembly. The coupler connects to a hard point onthe vehicle to form a link between the vehicle and extension platform. A small serviceplatform replaces the T head on the S-K intertanks, S-IC forward, and S-II aft armsand contacts the vehicle through a spring-loaded bumper assembly, Since the vehiclehorizontal deflections do net exceed four inches, the coupler employed with the Thead arms is not required.2.4.2.5 Control, Control cabinets, conta,ning hydraulic and pneumatic acctimulatorsand Gontrol -or the arm retraction and withdrawal mechanism system, are locatedon the service arm level, The preflight arms utilize two cabinets. The second cabinetemployed by the inflight arms actuates the redundant tower mounted cable retractionsystem, Cabinet number one controls the actuation of the arm rotation, disconnection,and retraction system. A hydraulic charging uni t, which consists of a stainless steelreservoir and two hydraulic pumping units, provides the initial charge and periodicreplenishment for .he service arm control system accumulators. During the final phaseof the launch countdown, the unit, which is mounted to the lower level of the LOT base,is de-energized and the launch sequence is completed with energy stored in the accumu-lator.2.4.2.6 Service Lines.
