  • Help with Aerialscope operations

    I picked up an old 1978 aerial scope, but the town I bought it from did not have the manual. I have scoured the internet. Does anyone know where I can get a manual?

    Other things I don't understand is how the interlock works on these older truck, the dept I am on the LTI interlock blocks aerial operations it the the outriggers are not deployed correctly, it does not seem that the interlock on the scope works that way.

    What kind of hydraulic oil does it use, it is a bit low and the dipstick/caps makes no mention of type of oil.

    I know many years ago we looked at a 'scope in Cherry Hill, NJ and the head of the shop at the time, Tom (don't recall his last name) was well know for his knowledge of Aerialscopes. Could be he retired, that was around 2005?

      Chevron Rando.
      Trying to see which grade.

      And when you go to set the jacks and outriggers, just put them all down as far as they will go, no matter the grade. DOWN! ALL THE WAY!

        We had an older Pirsch ladder truck (1964) in our dept that used ISO 46, but not sure about this truck. i just shocked that it is not on the filler cap and or dipstick.

          The 1994 Scope 75' we had in our company you had to put the two main outrigger pins in where the chrome rods on the pins made contact with a plate on the one side of the outrigger the rear facing side. Then there was a push button to release the the interlock and move the diverter control from the lower position(outriggers) to the upper positions(boom). Don't know if your rig has that being a 1978 it may have used a different interlock then we had being older. If it was refurbish by baker it may have what we had depending on year of refurbished.

          Call a seagrave rep to give you the oil specs.

          As for hill opps with scope baker trainer at the time on ours said ideal setup would have cab facing down hill jack front tires of the ground. With the rear jack until half bubble is out of tires and then outriggers where you don't lift the rear tires off ground so rear tires help prevent sliding this is when it is a severe grade.

            yes there is a push button about a foot above the transfer knob.

            On the push pins I dont see any wiring on the out riggers, the pins dont look like they contact anything.

            On the dash (cab) there is a yellow light that is illuminated that says "interlock", I am assuming that it is on because the truck's dipstick says 5 gallons low on hydraulic oil. When I push the button it still does not allow the solenoid to allow transfer

            thanks for the great info

              Update, did lay my hands on the manual, and just for completeness and future info seekers

              Hydraulic oil = shell Lo-hydraul 123, or equiv . they listed Rando HD is one of the equivs so kudos FWDbuff

              also TOWER412 is correct, there were wires at the outriggers pins.
