The 4" x" 4 tower diagonals carry loads to heavy- duty hot-dip galvanized steel anchor plates or hot-dip galvanized anchor weldments. The system of longitudinal and transverse diagonal bracing provides stability in a true tension-compression design.

All structural framing connections use 1/2" dia. galvanized machine bolts with either fiber-reinforced nylon shear connectors or FRP connector straps.

The fan deck is pressure treated exterior grade fir plywood designed for a uniform live load of 60 psf.

Access and Safety

The Sigma tower is designed to meet all OSHA requirements. A 3'-6" high guardrail system, complete with toprails, intermediate rails and toeboards, surrounds the entire top perimeter of the tower.

Aluminum ladders attached to the tower endwalls provide access to the fan deck level. Ladders begin at the cold water basin level and end at the top of the guarddrail. Each tower normally includes two ladders—one at each endwall.

Hinged doors through the endwall casing permit access to the interior of the tower at the basin level. Single-cell towers have one door. Multicell towers have doors in both endwalls, plus accessways through any and all partition walls.

Removable fan guards on Series 1000 models keep personnel away from operating fans. The galvanized, heavy-gauge welded rod guards lift off for easy access to

the mechanical equipment. The taller fan cylinders used on Series 1200 models effectively keep personnel away from the fan, eliminating the need for guards.

All mechanical equipment is accessible both from the interior of the tower and through the fan cylinder.

Every component of every tower is removable and replaceable.

Casing

Tower endwalls are cased with gray 8 oz/sq ft rib-type, fiber reinforced polyester sheets. Water and corrosion-proof,

FRP is immune to biological deterioration and requires no maintenance.

Casing ribs run vertically. Vertical joints between sheets are overlapped one rib and are sealed in the fill areas. Casing attaches to the structural members with stainless steel fasteners and neoprene bonded washers. Corner trim pieces are 12 oz/sq ft molded FRP.

Cold Water Collection Basin

Most Sigma owners install their towers over concrete cold water basins provided by others. However, you can choose a Marley wood collection basin as an optional accessory. (See page 11).

Consult your Marley sales representative for detailed dimensioned drawings and load schedules to help you with your basin design.
