19. Tower: A lightweight, ten-meter aluminum crank-up tower with optional anti-climbing plates, consisting of three 12-foot sections (BCD), an 8’ long, 1-½” (or 2”) diameter mast and 1-½“ (or 2”) to 1” mast adapter. The tower must be attached to the rear side of the housing as shown in Drawing 4719-1. The tower must be capable of safely supporting, without guy wires, a wind direction vane and a wind speed anemometer at the 10 meter, B-section height, and a motor aspirated shield containing temperature and relative humidity probes, a pyrometer and two spot lights with base at the top of the “D” tower section (approximately 12’ high). An Aluma Towers Model T-135 (with 3-12◊ sections) is recommended. Other features as follows:

a) Roof supports, tower base support, brackets, cables, cranks, etc. must be included so that the tower can be safely transported in the horizontal position on the roof of the housing, easily tilted/cranked to the vertical and then cranked to the desired height. A safety device must be included to lock the tower in a base support while in the vertical position and to its roof support in the horizontal (transport) position. All necessary tower hardware must be included. All hardware must be aluminum or stainless steel.

b) A hinge must be attached to the corner of the housing allowing the tower to pivot to and from its horizontal and vertical positions. Hinge “ears” must be welded to the outside section of tower at a point approximately 7-8 feet from the bottom of the tower.

d) The vertical cranking apparatus must include a safety stop.

e) The location of the tower as shown in Drawing 4719-1 is approximate. Consideration should be given to: the location of the tower, the ground fed service entrance, and any outside GFCI receptacles, so that they do not interfere with their respective operations.

20. OSHA approved safety railing with kick plates and ladder access opening, shall be installed on the roof. Rails shall be removable to allow for lowering of the tower and shelter transport. A removable roof access ladder with lockable safety / anti climb gate shall be supplied as well. A non-slip surface shall be applied to the roof surface.
