■ Many cooling towers are installed such that the base of the unit is
600mm or more above the roof or grade level. This makes it difficult
to get up to the foot of the attached ladder. The ladder extension alle-
viates this problem. Marley ladder extensions are available in stan-
dard 1524mm and 3353mm lengths.
■ Where cooling towers are installed on an elevated grillage or piers,
it is often difficult to get to—and through—the access door conve-
niently. This platform provides easy, safe, and comfortable access to
that door.
■ This platform provides easy, safe and comfortable access to the
