V.
INSTALLING THE LADDER ACCESS SYSTEM
A. Preparation for Mounting
Check both units to verify they have matching serial numbers.
Plan and lay out the entire installation before making any cuts or drilling holes in the body of the
fire apparatus. This will keep "out of service" time to a minimum and also help to minimize mistakes.
See Electrical System (Section B, page 7) before any holes are drilled into the apparatus.
Lay the two units on the shelf of the apparatus to that you can see where holes will be required for
the mounting bolts. There should be sufficiently sized flat surface underneath the mounting holes, free
of seams and obstructions where the bolts will pass through. Raise the ladders near the two units to
determine where they will lay when installed. The ladders must be evenly supported by each unit (the
same number of rungs should extend on the outer side of each ladder support).
When the ladder is raised and lowered in this position, it should clear protruding objects on the
apparatus such as emergency lights, hand rails, etc. Make sure that when the ladders are in the up
position they do not obstruct cross lays or hose reels.
Measure the "resting" depth of your ladder combination to determine how far your ladders will
protrude out from the hose bed wall (add depth of 6" for the retracted LAS System). In the event that
the actuator retainer casting (item 48, page 15) or inner arm casting (item 2, page 15) come into contact
with the stiffening rib at the top of the hose bed, you may have to notch out the stiffening rib to recess
the device (see page 21). In the event that the stiffening rib is notched, the exposed metal surfaces
should be painted and covered with an edge guard material. In addition, and in particular, if the
stiffening rib is notched, you may wish to add a backing plate (page 21) on the inside surface of the hose
bed wall. The plate will reinforce the hose bed wall and provide a good mounting support for the
QUIC-LIFT System. The edges should be rounded off, on the side next to the hose, and flat head bolts
should be used to mount the plate.
Bolts 3/8" or larger should be used to mount the base castings to the fire apparatus. When the bases
will only be mounted to the hose bed wall or only mounted to the shelf deck, 1/2" bolts should be used
with substantial backing plates (page 21) and supports. If you are installing the QUIC-LIFT devices to
only one surface, we suggest you contact one of our technicians before beginning.
