ESW4 Closed Circuit Coolers
Optional Sloped Ladders
When sloped ladders are supplied with a unit, they are shipped
in the basin section, if there is room. One sloped ladder will be
provided for each cell. Assembly is identical for each cell.
Sloped ladders are attached at a minimum of three points.
Taller units will have four attachment points. At each point of
attachment, the ladder will be fitted with a ladder bracket
assembly. The ladder bracket assembly looks like a metal box
and is shown in detail (component #4) in Figure
21
below. The
upper two assembly brackets are factory mounted to the ladder
and are not adjustable. These two brackets define the slope of
the ladder. The lower brackets are adjustable. See Figures
