Great replys. As a 12 year Operating Engineer before my Fire career I was a crane operator. Definetly stop by and talk to an operator. Better if their in the IUOE. You will get more accurate info. The general rule of thumb is the tonage rating of your crane or ladder truck in this case, is divided by the number of outriggers that you have. That then gives you the square footage of the pads to throw down. Example: 100 ton crane with 4 outriggers. 100 divided into 4 = 25. You then need 25 square feet under each pad. you should have a 5'x5' pad under each one. Example: a ladder truck rated @ 80,000 lbs totally loaded in service = 40 ton divided by 4 outriggers is 10 square feet per pad. As in other replys the situation will dictate if that is enough , not, or too much. Better safe than sorry. Also someone asked why the pins in the riggers and not the hydro. rams on the ladder. The outriggers once deployed are done being used unless you start to sink and need to extend them more, which you should be able to do without removing the pins. Just a safety feature. The rams on the ladder are constantely being raised and lowered so that feature is not available. I hope that was helpfull.

There have been some really good points brought to this thread. Our department uses the pads everytime. There is no set rule in our department on this, but just rather assumed or habit. Being captain of the department and in charge of the apparatus I would never like to see our quint set up without the pads....yes it might work just well without, but i dont want to see something happen to a brother because someone was in too much of a hurry to set pads.
We are a rural department. Not all surfaces we set up on are pavement or concrete. That is why I stress pads everytime. If the guys are in the habit of using the pads, then they wont have to think about if the surface is stable enough to use the truck without the pads.
Trucks have evolved alot throughout history. I remeber seeing photos of old trucks that had screw jacks. With hydraulics now days, jack are deployed quite fast. If the truck is crewed like it should be, then two guys can get the pads out while one or two guys set the riggers. Again, safety of firefighters is main consern when operating. Just as the saying goes, you cant help anyone if you dont look out for yourself. If a truck fails because of not using the pads not only is a civillian going to get hurt, but also a brother or two.
The truck we operate is an e-one. Among the major selling points of the e-one ladder, the pinless riggers was a major. I dont care for the pins at all. Yes they are a great safety device, but it just makes me feel like the manuf. doesnt trust their system. Just a personal feeling.
I am really interested in this topic and i am looking forward to reading what other departments are doing and what other opinions are.
Stay safe out there guys.

I have a couple of questions for the NYC guys. I was recently transferred to a house with a 105' RM Pierce tower ladder, so I am still trying to get used to using it in case I am floated to it for a shift. Do you all ever have issues where your outriggers sink into the pavement at all? It gets hot here in NC in the summer, but probably no less hot than NYC with all the pavement.
Are you all on an Eng. or a truckie? Just wondering.

"Trucks have evolved alot throughout history. I remeber seeing photos of old trucks that had screw jacks. With hydraulics now days, jack are deployed quite fast."
We had a older Pirsh with screw jacks, and I have yet to see a truck set up faster. It is all on how the rig and your crew is set up. With the old Pirsh the driver would go into PTO while the steps would drop the pads and the screws. By the time the driver was on the turntable and raising the ladder all 4 outriggers were set, with pads down. Around 25 to 30 seconds max.
Anyway, on a rural road (blacktop) I have seen the pads sink slightly 1cm or less. I haven't seen it on a regular street. Use the pads, they should be next to the jacks, if not MOVE THEM.
Remember why we have the truck, to save lives and access the upper stories and roof. Set the entire truck up to streamline those operations. I have seen saws, and other tools along with hose (why it would be on a truck is beyond comprehension) electric reels and all types of junk in the baskets of modern tower ladders. We can hardly get around how will victims of a fire do it?
Anyway, do what the manufacturer wants, if they told you to use the pads then use them.
If you are not comfortable with where the pads go then try this. Extend the jacks on one side, then move to the other side while another FF places the pads. Finish set up on the first side while he places the pads on the second side. It is not ideal but it beats moving the pads because they are in the wrong place. Other things can be ised like your pike pole to measure distance.
As for the pins (at liest on a Pierce) they are a safety item and not needed for operation. Set up the ladder and when you get a second put the pins in.
FFFRED I can speak for my department, when inserviced on our ladders (E-One and Pierce) they said the pads were needed for softer ground and not needed everytime we set up. Our shift commander threatened to write up anyone who used them without the pads. (this came from the chief according to him) I guess we are unable to think for ourselves. We have the same rule about short jacking the Pierce. I'll take my hits if it saves a life. The bottom line is. Learn your truck inside and out and learn what it can and can't do. Then when the Sh*t hits the fan and what you do will save a life do the right thing.

Train and work as the team that you train to be and it will take no more then an additional few seconds to get the pads out. On the calls where you see that the stick needs to get up FAST for a rescue you can likely get away with skipping it if you have a solid base, but there is no need to skip the practice in the routine.

On days I am driving the truck, on every fire call, I set the truck up for use (even on smells and bells) that way, when i really need to do it it is automatic.
Either you put jack pads down or you don't. I suggest that you do because the one time you'll need to you'll forget to do that. Ever try to bed a ladder that is fully extended with the truck on its side. Do it for safety and everyone goes home.

We were trained by Snorkel reps to use stabilizer pads whenever the aerials are being setup to distribute the weight. It doesn't matter what the ground environment is at the time.
We have an 85' Snorkel and a 75' Telesqurt. We drop the ground pads every time the units are setup. The pads on the Snorkel are solid steel and I think there about 2'x2' by 1" in thickness. The pads on the Telesqurt are that same except their made out of aluminum. We were told by Snorkel that we can not use the aluminum pads with the Snorkel cause of the weight difference in the two aerials but ALF has stated that they now use the aluminum pads on all of their Snorkels. (interesting)
Has for icy conditions, I would prefer to lay down some oil dry to act as a form of traction for the pads so that when the outrigger shoe it's the pads they don't slide away from the truck.Jim Shultz

About the jack knife question
We run a 100' ALF tiller. The book recommends you jack knife for maximum reach of the ladder but it isnt necessary. Some of the older Seagraves recommend always setting up in the jack knife position especially for a ladder pipe operation.
We also have never had a problem with the pads sinking into the pavement. Just remember nerver drop em on manholes and train/trolley tracksJust another one of the 99%ers looking up.
