The document provides training objectives and procedures for operating an aerial ladder truck. It outlines how to position and stabilize the truck, erect and manipulate the boom, recite load limits at different boom angles, and describe emergency operation procedures. Tactics and uses covered include rescue, ventilation, elevated master streams, fire suppression to upper levels, and scene lighting. Load capacities and stabilization requirements are detailed for different boom angles and conditions. Emergency procedures for hydraulic failure and manual operation are also defined.

1. Model T-55B
Water Tower

2. » Firefighter will describe 5 uses of aerial
apparatus and briefly describe tactics for each.
» Firefighter will position and stabilize apparatus
on simulated fire ground.
» Firefighter will erect, rotate, extend, and
position boom to a target.
» Firefighter will recite load limits given a boom
angle and condition.
» Firefighter will describe emergency operation
procedures.

3. » Rescue
» Ventilation
» Elevated master stream
» Fire Suppression
(access to upper levels)
» Scene Lighting

4. » Overhead obstructions
» Ground obstructions
» Slope
» Capacity and reach limits
» Specific notes for:
˃ Rescue Access to upper levels
˃ Ventilation Fire Suppression

5. » With engine running, set parking brake
» Engage the power take off (PTO)
» Chock front wheel

6. » Use a spotter
» Look for
overhead
hazards

7. » Engage
master switch
» Turn on Panel Lights
» Don’t use “Fast Idle”
unless speed is
essential
» Nothing works
without holding the
“Dead Man Control”

8. » Deploy Outrigger jack plates
» Use wooden bearing pads when required

9. » Select “Jacks”
» Set Outriggers individually:
» downhill first
» uphill second
» SAFETY: Use a spotter when outriggers are deployed
» Line up edge of pad with “pin”
» Extend outriggers until rear bumper raises 3” -
4” and weight is shifted from tires to the
outriggers
» Raise until selector will switch to Boom
» Ensure truck is level

10. » Switch over to boom control
» Walk around vehicle to verify stable condition
» Ensure Boom Functions
switch is in correct position
˃ In: Midship Control
˃ Out: Rear Control

11. » Check overhead hazards
» Elevate boom
» Rotate to desired position
» Extend to desired height

12. » Standard hand signals for controlling cranes
operations

13. » Due to a part failure
˃ Water cannot be pumped directly to the boom
˃ Replacement piping has been installed to allow water to be pumped
into the boom
˃ A PINCH POINT exists between the ladder base and this new piping

14. » Due to the PINCH POINT
˃ The boom cannot be raised
higher than 50o
+ Note the white arrow
˃ If a spotter is used
the boom can be raised
higher to 60o

15. » 1000 GPM @ 100 psi at the nozzle, with ladder
at 90o
= reaction force of 500 lbs.
» Live loads, due to nozzle reaction & distribution
of firefighters on the ladder are most greatly
affected when the boom is fully extended and
nearly horizontal

16. » The greater
˃ the horizontal distance from the nozzle to the centre of the truck
˃ the radius of the line of action of the nozzle stream to the boom pivot
» the greater the effect on
˃ boom stress
˃ truck tipping moment

17. -10 to +90 No load 1000 GPM any
direction
45 to +75 300 lb tip
500 lb even
1000 GPM any
direction

18. -10 to +45 500 lb tip
900 lb even
0 GPM
45 to +75 800 lb tip
1600 lb even
0 GPM
-10 to +75
tip supported
1600 lb even 0 GPM

19. » Erect and position boom for best advantage.
» Bring nozzle position out of storage and into
desired position.
» Water delivered by truck pump through 4” hose
to 4” rear supply
˃ Boom cannot be rotated once line is charged

20. » Nozzle can be operated from:
˃ Rear
˃ Midship
˃ Umbilical
˃ Ladder Tip

21. » Control pump throttle
to get 100 psi @ nozzle
˃ 1500 gallons per minute at 100 psi
˃ Friction loss through 4” hose is negligible
˃ Elevation loss is 0.5 psi per foot
˃ Friction loss through “Master Stream” is 25 psi

22. » Ladder communications
on TAC 3
» Pump operation
from step due to
electrical hazard
» Ladder can be
raised/lowered
& rotated with a
firefighter on it
» Ladder CANNOT be
extended/retracted
with a firefighter on it

23. » Generator
˃ Right Side, rear compartment
˃ Four Halogen Light MAXIMUM
» Boom Lights
˃ Two 110 volt lights at tip of boom
» Intercom
˃ Rear Panel
˃ Midship
˃ Tip of Ladder

24. » Air System
˃ Take mask from compartment at rear of Ladder
˃ Turn on the Air Bottle at the base of the ladder
˃ Don the mask at the tip of the ladder
+ XL30 mask
+ Screws into regulator
+ Switch regulator
from Don to Use
» Fall Restraint
˃ Required when working
on Ladder
˃ Belts located in rear
compartment

25. » Shutdown
˃ Nest the nozzle and drain the tower
˃ Rotate Ladder using pointer on turntable
˃ Retract Ladder
˃ Lower Ladder into cradle
+ XL30 mask
+ Screws into regulator
+ Switch regulator
from Don to Use

26. Overrides
» Keys are in glove box
˃ in cab
» Jacks Override:
˃ Raise boom without jacks being
extended
˃ Used when tilting cab forward for
maintenance
» Boom Nested Override:
˃ Move jacks when boom is not
nested

27. Turntable
» It is possible to
rotate turntable
manually
˃ Housing hole is not centered
˃ Need a wrench

28. Power Pack
» To be used in case of
failure of engine,
transmission, PTO, or
main hydraulic pump.
» Small electric
hydraulic pump
˃ Uses lots of power
» Controlled by “Aux.
Pump” toggle on rear
panel

29. Hydraulic Supply Failure
» Complete hydraulic
failure.
» Disconnect and
reverse hydraulic
lines.
» By service personnel
only.

30. » Firefighter will describe 5 uses of aerial
apparatus and briefly describe tactics for each.
» Firefighter will position and stabilize apparatus
on simulated fire ground.
» Firefighter will erect, rotate, extend, and
position boom to a target.
» Firefighter will recite load limits given a boom
