TROUBLESHOOTING

 

All units are tested after final assembly to ensure proper operation and adjustment.  no further adjustments 

should be required unless excess movement is noted.

 

A.  Excess Movement of the Rack and Ladders

 

 

If the rack and ladders appear to be moving more than when the System was initially installed, it is

 

probably due to one of the following reasons:

 

 

1.  Ladders and rack not properly seated against the vehicle mounted ladder stop.

 

 

 

A ladder stop must be provided by the apparatus manufacturer to prevent the ladders from 

 

 

swaying.  If the ladder rack is not touching the stop, swaying will occur.  Shims may be required to

 

 

close the gap.

 

 

2.  Booms move freely when the rack is pushed or pulled by hand.

 

 

 

use the following procedure for adjusting the hydraulic cylinder (8), bumpers (16) and latch (9).

 

 

refer to figures 13 and 14 on page 17 for numbers in parenthesis.

 

 

 

a.  Remove ladders with the rack in the down position.  Raise the unit back up approximately

 

 

 

3/4 of the way and loosen the two bumper lock nuts (65).  Turn the bumpers (16) towards the

 

 

 

backing plate (6).

 

 

 

b.  raise the rack up until the cylinder is fully extended and the latch (9) closes.  The hydraulic

 

 

 

 

pump will slow down when the cylinder is fully extended.

 

 

 

c.  Pull booms (2 and 3) out by hand to apply load on the cylinder (8).

 

 

 

d.  Check the gap between the inside face of the latch (9) and the outside face of the latch

 

 

 

bar (10).

 

 

 

 

The gap should be around 3/32" when pulling out on the boom assembly by hand to take the

 

 

 

free play out of the unit.  if the gap is less than 3/32", the overall length of the cylinder has to be

 

 

 

lengthened.  if the gap is more than 3/32", the overall length of the cylinder has to be made

 

   shorter.

 

 

 

e.  The length of the cylinder may be adjusted as follows:

 

    1.

  Loosen the 3/8" socket head cap screw clamp bolt on the shaft clevis pin.

 

    2.

  Lower the rack so the latch (9) opens and the latch bar (10) just clears the latch.  This

 

 

 

 

takes the pressure off the cylinder which will make the next step easier.
