Turning radius for fire truck

I need to set up a turn-around at the end of a 400' drive for fire truck turns. Not a cul-de-sac but a tomahawk. What radius or vehicle type? I know, that's a bit like "how high is up?" but let's stipulate a mid range vehicle rather than, say, an urban ladder. Any leads appreciated! rs

Fire Truck: Turning Radius: 48' Length: 32' Width: 8' Height: 9'-8" Overhang Rear: 10' If you need it, I have charts for different vehicles extracted from Architectural Graphics Standards that I could email, I think they're tif images? - Jim "TCEBob" wrote in message news:40216d92$1_1@newsprd01... > I need to set up a turn-around at the end of a 400' drive for fire truck > turns.

I am working a project for a supermarket and need to know the turning radius for there semi-trucks. Do you have that info as well. I wouldn't mind having all the charts for different vehicles as well. My email is jwilkerson@vandellce.com. Thanks.

Hi, An infinitely better solution is a program like "Autotrack" from Savoy. This gives you a huge range of vehicles, ability to create your own and ability to sort out what happens when you go forwards, backwards or any combination of these at any speed. The results are grip editable and can provide an excellent visual view of the vehicle tyre track and overhangs. -- Laurie Comerford CADApps www.cadapps.com.au "TCEBob" wrote in message news:40218525$1_1@newsprd01... > Jim, I would be eternally grateful.

Laurie, I slaver at the thought. But this time all I really need is the pc equivalent of the turning diagram. I will look it up and check it out but it has to be really inexpensive. rs Sorry for the repeat, the first one went to e-heaven.

So I went to the site and downloaded the demo. Very discrete, these Brits; not a word on the site about price. Please tell me what it cost when you bought it. But gently. rs

You should explain to your boss its unethical for you to be designing life safety facilities like fire truck accesses without the necessary tools and or training.

I would flat out refuse to take responsiblity for those drawings and certainly wouldn't put my initials on them. (What usually happens when you design something different is after it is built the fire department sends a truck out to test it. Expect a phone call if they can't turn around.)

If you are forced to design it on a shoestring budget you could consider calling the responding fire hall (not 911) and explain to them what you are designing. They should be able to give you their guidelines and tell you what their biggest truck is. Then call the manufacturer for turning radius or 3-point turn specifications. (I've done something similar for bus stations and facility specific articulated buses. They provided a scale diagram which I was able to scan, import and rescale correctly to check my designs).
