CHAPTER II, SECTION 3 (Neg. No. W-864-8) Figure No. 2-65. Stations 6001 and 6002 — How. Platforms at the 12-foot, 41-foot, 50-foot, and 64-foot levels contained a 624-foot-diameter opening in the center, and the portion of the deck from the front edge of the platform to the opening was designed as-a pair of hinged platform sections which were counterweighted for manual operation. Additional cutouts were made in the grating around the opening at the 12-foot level to allow clearance for the missile fins and pods. A platform was provided at the 77-foot level to seat the elevator-hoisting equipment. Checkered plate flooring covered an area 8x24 feet. Louvers, 3x5 feet, were installed on four sides of the tower at each of four levels. A pair of swing doors, 7 feet high, provided a 14-footwide opening on the bottom of the front face of the tower. A 9-foot-wide rolling door hung from mechanically operated trollies. The door extended from the top of the swing doors to the top of the tower and was supported laterally at the 12-foot, 41-foot, and 64-foot platform evels. A personnel elevator, 4 feet square, operated to all levels. Interlocked safety gates were pro- vided at each platform level as well as other Page 126 standard safety featurs. An access ladder extended the full height of the tower on the inside. The tower was supported on four 4-whee] trucks equipped with hydraulic brakes. Movement of the tower was effected by a simple winch and cable system between the firing anc auxiliary pads located 400 feet apart. The winct was located just beyond the auxiliary pad but was controlled from within the tower. Power was supplied from three 150-kv diesel generators located about 600 feet from th firing pad. The power connection was made through a cord located on the tower and plugge* into a receptacle on the firing pad. The elevato however, was operated from a separate generatc . to alleviate the high starting current required to drive the elevator motor. Lights and recep- tacles were provided atall the platform levels. The firing pad was a 200-foot-square stabilized area with the tower located in the center. The foundation for the tower at the firing a auxiliary pads consisted of 12-inch steel beari: pile clusters with concrete caps 8x11x4 feet deep. Provision was made to tie down the tower to its foundation when it was subjected to hi :
