21. Ladder Extension Dial - Indicates, in feet, the length the ladder is extended.
22. Water Tower Pressure Gauge - Indicates water pressure to the water tower.
A detailed description of the operation of the ladder controls is given under the heading "Ladder
Hydraulics".
The Ladder Extension Dial (see Figure 4-8, number 6) is controlled through a cabling system attached to a
vernier screw on the extension winch drum and is channelled to the ladder Control Console through a
series of pulleys to attach to a dial mechanism which positions the indicator. For a description of the
operation and calibration procedures for the Ladder Extension Dial, refer to Section 8.
The Ladder Inclination Dial (see Figure 4-8, number 3) is controlled through a cabling system attached to
Section One of the Ladder Assembly and channelled to the Ladder Control Console through a series of
pulleys to attach to a mechanical dial mechanism which positions the indicator. A detailed description of
the operation and calibration of the inclination dial is given in Section 8.
Four Outriggers provide stability for the ladder when it is in operation and must be deployed before the
ladder is used. Two Outriggers are located at mid-chassis, on each side of the truck and two are located
immediately aft of the rear wheel wells (see Figure 4-9).
