Roll Cage - REALLY needed????
Dangle_kt - 24/9/07 at 05:46 PM

Has anyone ever rolled a Locost?

They are pretty dam low and wide - if you have rolled one - what speed and what were the circumstances?

just interested

Yeah

did he survive??????
thats bad

I think the answer to the OP's question is yes ;-)


blakep82 - 24/9/07 at 05:58 PM

probably not really needed on the road, but would you really want to wait til something happens to find out?

Hope he was ok!!!!!!!!

After seeing that I've just moved a Roll Cage up to second on my list of winter upgrades

As we are all enthusiastic drivers a roll bar is worth having and in my opinion the bar adds to the look of the car.
Some early Lotus sevens and the early robin hoods were offered with the roll bar as an option but just look if something is missing

It's not the low and wide bit that we need to take into consideration, everyone I know who's rolled a car has either gone up / hit a bank (not the kind with money in) or spun and hit a kerb, this could happen to anyone in any car I guess, I'm making a big big cage, but that's partly to strengthen the rear of my car as at the moment it's held on with dust, cobwebs and luck.....

I believe he only broke an arm. Which is effectively nothing after an off of that magnitude.

More discussion about cages/that crash/binbags for condoms (!) in this thread http://www.locostbuilders.co.uk/viewthread.php?tid=56410

WOW!

Scary stuff!

I was interested - I have a roll cage, but was just curious.

here is mine, its pretty substantial and means I have to climb in through the top! like dukes of hazard but with much less style or grace.

I only have a hoop and backstays at the mo, and did have need (when I was adding the b/stays) to drive without protection. It felt like riding an m/c in t shirt and shorts

I will be having a front hoop and front rear connection soonish, mapbe with side impact protection and a removable screen (with integrated wiper)

If you feel the need to have a full roll cage, then at least get it manufactured to conform with MSA regs. Anything less could potentially be more life threatening in an accident than having a single roll bar.

not a 7, but shows well why roll bars are needed

How do double hoops fare in a crash? I always found 'm better looking on road-going Locosts than the big bars/full cages.


blakep82 - 24/9/07 at 08:48 PM

think i've got the roll cage fairly well covered

That's a roll cage with bits of chassis attached!

That will be the heads then!

I've told this story before, but...

One of my son's friends had a Caterham Superlight with a full cage. He was going quite fast on wet roads when he came across an unexpected sharp bend. He slid across the road, hit the opposite kerb with both wheels and flipped the car at some speed. He walked away with only his pride hurt.

As a follow-up, Caterham straightened up the car for a wad of money, and when they gave it back they told him that all the shocks had been wound up to max, and that they'de re-set them to sensible damping settings! That was a cock-up by the previous owner, and this lad was not techie enough to realise.


brynhamlet - 25/9/07 at 05:52 AM

All I can say is the driver of that Caterham was lucky, but it's a testiment to the strength and safety of the cage.
For road use I would not entertain anything less than what my car has got i.e. braced roll bar. Landing on my head in the unlikely event I did roll it, without a bar does not bear thinking about.

standerd roll bar rivnutted on driver walked away unhurt

I remeber long discussions about that MK crash a few years back, and don't want to start them again, but PLEASE PLEASE PLEASE - no one RIVNUT your roll bar on! Nothing could be further from good engineering.

I can only imagine the car above did a 'pure' roll: I'm sure with any sliding the bar would have ripped straight off.


James - 25/9/07 at 09:34 AM

I couldn't find it on Youtube, but there's a video of a guy barrel rolling a 750mc Locost through the air. Think it was Castle Coombe a couple of years ago.

Pretty sure he walked away.

As for rivnuts..... agree wholeheartedly with Matt!


procomp - 25/9/07 at 01:18 PM

Hi locost only been to castle coombe once. And that was this year although one was on its roof. I think it was the caterham incident James is reffering to.

Also if thinking of having a cage done to comply with MSA/FIA it will be worth researching the blue book as some people who are supplying cages are obviously not aware of the changes made a few years ago. So some cages supplied over the last few years do not comply with this criteria.

cheers matt
