Operator`s manual

A safety rail (10) is attached to the sides of Section One to catch the rear end of Section Two if it should
ever, by reason of excessive torque, become disengaged from the Section One rail. The second ladder
section (see Figure 4-5) is nested into Section One and is free to ride over Section One on the rear
mounted nylon slides (7) and the Section One Nylon Slides. Two sets of pulleys are mounted horizontally
at the forward end of the second section (1) and are canted to cause the Extension Cables to pass under
the ladder section in order to feed onto the winch winders, located on the underside of Section One. For a
description of the extension system and placement of cables and pulleys, refer to para 4.2.
Also located on the forward end of Section Two are three pairs of nylon slides (4) to support Section Three
and a set of Locking Pawls (2) to engage in the rungs of Section Three when the ladder is extended. Two
pulleys are mounted between rungs toward the forward end (3) to direct the Retraction Cable from the top-
side of Section Two to the under-side. Each rung is equipped with a no-slip tread (5).
Two pulleys, having two sheaves each, are mounted horizontally at the rear of Section Two (6) to change
the direction of the Extension Cables. A safety rail (8) is attached to the sides of Section Two to catch the
rear end of Section Three if it should become disengaged from the Section Two rail.
The third ladder section (see Figure 4-6) nests into Section Two and is free to ride over Section Two on
the rear mounted nylon slides (7) and the Section Two nylon slides. A Retraction Cable Compensator
Assembly (3) is mounted toward the forward end of the ladder section.
Also mounted at the forward end of Section Three is the Water Tower Assembly and guard rails (8), the
Water Tower Control Panel, the PA System (9), two each of folding foot steps and kneeling guard
assemblies (1,2) and axe (4) and pike pole (5) holding brackets. The rungs are equipped with no-slip
treads (6).
