Truck Driver

Question 1

Business District setbacks from curbs

Answer 1

10-12 feet

Question 2

Short Jacking Operations

Answer 2

If one side is short jacked, you cannot work off the short side, only the full side
If both sides are short jacked, one can only raise and lower out of cradle
Short jacked side needs to be extended far enough to remove pins and insert them

Question 3

Outrigger Deployment Ops

Answer 3

Extend both stabilizers on one side
Extend both stabilizers from other side
Low side: move stabilizers down to unload suspension or 2 degrees past level
High side: move stabilizers down to unload suspension
and bring to level
Ensure front tires have contact with ground with slight
bulge
Ensure all 8 green lights are on
Pin Stabilizers

Question 4

Aerial Operation Speeds

Answer 4

Turtle - will always operate without high idle
Normal - will operate in high idle if 2 functions are being used
Rabbit - will always operate in high idle

Question 5

Aerial Controls (at tip)

Answer 5

Red momentary switch (remote aerial master) dead man engaged
Tip controls are 33% slower than pedestal controls
RAMP system applies
Rider must wear truck belt and secure himself to laces of ladder (not rungs or K braces)
Feet must be on pads
No leg locking
Rider is not to extend or retract the ladder if foot pads are within 10 feet of upper mid bed

Question 6

Ladder Overloading

Answer 6

Load Minder shuts off at 45 degrees
Amber lights on bed section will flash and alarm will sound.
Operation to correct:
1. Remove or reposition ladder occupants
2. Retract ladder sections
3. Slowly increase ladder elevation

Question 7

Bedding the Aerial

Answer 7

Ensure water supply shut off
Open the main drain
Raise, Retract, Rotate, Lower
Walk the ladder before bedding

Question 8

Walking the ladder

Answer 8

Mushroom Switch OFF
Ensure roof ladder, pike pole, axe are secure
Ensure nozzle is opened, centered, up and on a stream pattern
Ensure standpipe gate valve is closed
Ensure waterway is fully pinned to desired fly section
Check cables, pulleys, communications equipment

Question 9

Emergency Power Unit (EPU)

Answer 9

Operates off battery power
To be used in lieu of PTO, if PTO fails
Should be operated once a week
Run for a period of 30 mins, then 30 mins cool down

Question 10

Rear Stabilizer Control Hatch (with EPU)

Answer 10

For stabilizers
“Multiplexed” switch that is powered by electronic computer
When used with rear stabilizer controls all safety envelopes are still being utilized

Question 11

Turntable Pedestal (with EPU)

Answer 11

“Multiplexed” switch that is powered by electronic computer

When used with pedestal controls all safety envelopes are still being utilized

Question 12

Hatch behind drivers side access ladder (with EPU)

Answer 12

For Ladder and Stabilizers
“Hydraulic” switch is hardwired to battery and hydraulic system
If the electronic “multiplex” system has failed, the EPU switch is the hatch behind the drivers side aerial access ladder will be the only one functioning

*When used with hydraulic override valves on turntable and side access hatches the aerial operates with no safety envelopes

Question 13

Global/Manual Overrides

Answer 13

Three Total:
Global Override
Stabilizer Manual Override
Ladder Manual Override

Question 14

Global Override (rear stabilizer control hatch)

Answer 14

Will bypass all safety envelopes in “multiplex” system
Used to get out of trouble only
When in use, “multiplex” records conditions of all sensors to hard drive

Question 15

Manual Overrides

Answer 15

1 for stabilizers (behind driver side access ladder)
1 for ladder (in turntable)
If either hatch is opened an alarm will sound and message will appear in command zone

Question 16

Why do we extend all 4 outriggers?

Answer 16

All other units coming will have to work around apparatus

Question 17

How should pins be placed on stabilizers?

Answer 17
