        I'd bet this is pretty much a new stick. Weren't the tip loads of the old 135 considerably less than what they're touting on the 137?

          They are claiming that it will reach 13 stories. Any fireman knows that this truck would have to be set up right next to the building and be raise almost at a 80 degree or so angle.

          They don't say and they won't either, about buildings that are set back from the street maybe 50 or so feet and no way to get up alongside those. Take the apartments building that are set back from the parking areas that at 0200 you have vehicles headed in to the curb that you have to try to position the truck to get the maximum reach for any operation.

          Tall ladders are nice guys. We ran 100 foot tractor drawn for years, no they didn't ever get above the 7th or 8th floor on even the best days we had.

          We have argued with sales people for years claiming this or that. As a side note a bullard hemet salesman came by the fd drill school one day claiming this and that about their new helmet. He said nothing can perpetrate the shell.

          I said "Oh nothing Huh"? He said yup. I took a number 2 phillips screw driver in my right hand and drove it all the way through the shell, impact cap. He said that it should not have done that. I asked him if he would like to put it on his head and I try it again? He picked up his helmet and walked out, got in his car and drove away. We never saw him again.


          Moral of that story, don't believe nothing they are saying and half of what they are showing, It isn't fireman proof!

                  And that even holds up mathematically!!! I just flashbacked to geometry class and worked it out...

                    One the hydraulic side... I notice the waterway is pinned on the 2nd to last fly section, so it's max elevation is 110'. I would have been surprised is it was located at the tip.

                    Here's they're dilemma if they put it at 137':
                    137' elevation, minus 4' where the pump impeller is above the ground, equals 133'. 133 x 0.434 = 58 psi head pressure.

                    250 psi is max the pump is rated at.
                    250 - 53 psi head pressure = 197
                    197 - 100 psi nozzle pressure (NFPA requirement) = 97 psi.

                    So the total friction loss from pump to nozzle, at 1,000 GPM cannot exceed 97 psi. And that's through the valve, collector assembly, and ladder piping.

                    Anyone buying one of these would be well off to buy a 2-stage pump rated at no less than 2,000 GPM.


                    Under-slung stabilizers? You can count me out.

                    Don't be fooled by the "750 lb" marketing gimmicks guys. The rated tip load on this aerial is 250 pounds. NFPA requires an aerial ladder to hold it's rated tip load at any angle & any elevation. At full horizontal, this aerial holds 250 lbs. The 750 lb tip load is at higher elevations, and/or shorter extensions.

                    This reminds me of the old ALF and Seagrave aerials with inclinometers showing their tip loads and extension capabilities.

                      I'm a moron. I'm sure its the same stick as of old.

                      Look at the load chart and it looks to have similar ratings as that of the old 135.

                        If you scroll up above the load chart, there is an impressive picture of a high access with the truck still away from the building.

                          From their web site....

                          Buildings aren’t getting shorter. Fires don’t have a maximum height limit. So why should your aerial ladder be any different? Reaching more than 13 stories high, the new CR 137 is North America’s tallest aerial ladder.
                          The CR 137 features narrow criss-cross under-slung stabilizers and a speedy set up – less than 45 seconds. The welded extruded aluminum ladder combined with advanced engineering provides a 2.5 to 1 structural safety factor, exceeding NFPA requirements. As with most E-ONE aerials, the integral torque box frame offers a rock solid foundation for the chassis and aerial, while providing a lower center of gravity than a bolt-on torque box for improved vehicle handling. Perhaps the most impressive feature of the CR 137 is its ability to reach a target that is 110’ high AND 82’ horizontally off the side while supporting a 750 personnel tip load. For maximum reach, strength, stability and safety, make sure your crew is riding in the new E-ONE CR 137.


                          I still would be shy of this thing.

                            Yet many large (and small) departments across the US found success with the older 135' models?

                              However, compare Smeal's 120 footer tip load at any angle as food for thought. Yes, I know its shorter...

                              And yes, I know lots of rigs are still running around with a 250 pound tip load at various elevations and angles.
