roll cage info (design,cams,rta)

[oldcorollas]

i am sure you are allowed to have a full for the street, as long as it is engineered. i was looking to do it myself, but i have thought abit about it and i think my like is worth a bit more than the $1000 it would cost to get a proper one built.

previously in NSW you could have front half ONLY if it met the requirements for head space and was foam covered. in the majority of cars, it is not possible to provide that amount of headspace (acoording to the diagrams) and so a front half of cage was not legal.

new national regs draft.
http://www.dotars.gov.au/transreg/vs...28sept2005.pdf

section LK8

only 4 point allowed. removable 6 point is allowed.
fixed 6 point cage is NOT allowed
it even specifically says cages with tubes running down Apillar and Bpillar
are not suitable for road use

figure LK14 shows head space requirements

also says seat belt mountings can be incorporated into vertical section of main hoop, but doesn't expressly prohibit mounting anywhere else.. would need to provide similar strength to main hoop tho.

it also states that horizontal braces alongside front seats are not acceptable (from acces point of view)

if you have a workshop that can certify a full cage before the new regs come in, better get it done quick

I know in qld you can have a full roll cage you just have to get it engineered/ blue plated. The car i brought was from nsw and it did have a full roll cage but they cut the front part out due to the thinking it was illegal but well they may be wrong

[45aken]

when will these new regs come in?!
if i cant go a full cage, is there even much point in spending the $xxx on a half rear?
worst comes to worst i'll half rear then seam weld/brace the front.

rear 4 point from bond roll bars is only $539!, $839 for the full cage. cams approved etc

Ring Brown Davis Automotive in Melbourne. David Brown I think is on the CAMS committee for roll cage design. He would also know the regs for all states regarding cages. They can sell you a kit for a 6 point weld in cage including intrusion bars ( both around dash and through dash).
Cheers.

He is also on the Vic RTA advisory committee, so he can give you the definate word on the topic, at least for Victoria.

Anyone located in QLD need not have to worry about these DOTARS regulations, as these are drafted from tha current QLD laws and therefore will not change.

In saying that, it is possible to get a 6 point cage engineered/plated, but the requirments of DOT/RTA/CAMS/ANDRA or differ a little and make it harder to comply. An example is with the current laws you are not allowed side intrusion bars, but for ANDRA and I think maybe CAMS you do need a side intrusion bar that is WELDED in, and not bolted in...

[takai]

For CAMS it varies, and you definately require a side intrusion bar if your car didnt come with them standard. You can run without one if the car came with side intrusion bars in the doors.

Basically it is all detailed in the CAMS manual, which i would advise anyone going down this track to read carefully.

What!? Side intrusion bars not allowed?? Pfft, what issue of Hot4's did you get that from?

[Forcefed6]

They come from the current regulations for mod plates...
This came straight from the reference material, and I will get a copy of it on Monday just to verify it.

And it didn't come form Hot4s cause I don't read it...

So why is it that we can legally fit side intrusion bars in all cars on our cages?

[w810sc]

hi,
"triple G" or "GGG" does roll cages, located in Anvil Rd toongabbie or winston hills

it says in the DOSTARS book that you cannot run side intrusion bars. this is what im so confused about i swear everyone has their own theories on cages(from gov regs to cage builders, engineers and RTA). maybe i'll jus speak to an automotive engineer and then see. RTA dosent know S^%t either.
how hard is it to stick to regs these days, in dotars is says no intrustion bars due to accessibility or something.
so basically it;s ok if my door crushes in and messes me up, but it's a big no no if i have to hop over a bar to get in my car?!?! it's stupid.

i even talked to those bond roll bar people and the bloke reckons that ur not legally allowed to run harnesses on the street. makes me kinda wonder how good those cages are if he says crap like that.

cool1, can you link a copy of the QLD regs about cages? that should put an end to the speculation..

From the (really bad) Qld Tpt web site:

see pge 23 Modification_Jan05v2.pdf (433Kb) - not overly helpful as most of the mods that folks here would undertake are listed as 'complex' modifications.

About the Light Vehicles Mods:
clickme.

fwiw, Vehicle inspection guidelines used for standard safety inspections (in Qld)

Specific info sheets about many kinds of vehicle mods (but nothing on internal roll bars)

Unfortunatly we have to pay for the Blue book which comes as a hard copy, so I cant link to it.
But, I will try and scan the relavent pages and post them here. Give me a few days and if I haven't posted it PM me a reminder.
