Proposed Midget Technical Change - Head Protection Bar (Read 1,327 times)

[percy]

Not much discussion online about proposed technical changes.

Such changes are out for consultation until April 30th. One that caught my eye was a proposed addition of a head protection bar or halo.

I'm no physicist and the detail is not in my area of expertise so I'll defer to others, but prima facie the idea/concept makes sense to me. There seems to be good rationale for the addition.

Look forward to others airing their thoughts.

One of our rescue crew at Waikaraka was asking about these a few weeks ago. Does the Halo impede extracting an injured driver? And there are bolted/bracketed on and welded on ones. Interested in peoples thoughts.

Good to see a chassis manufacturer has submitted a proposal ,but is this proposal going to be a optional piece of fabrication only .
Has alot of merit to me as safety is paramount especially the top of the cage preventing head and neck injuries ..

According to the proposal, ....optional... and theyve done tests which indicate driver extraction is not hindered. Some manufactures offer halos as an optional extra at present such as XXX and J&J. As long as they are not too high...which might make it something extra to dig into the track in a bad flip... it seems a good idea.
I,d like to see the extra brace that the WoO has mandated this year incorporated also. There's usually a bit of a trade-off i fugure in some features. Make it too strong, and the forces involved still have to go somewhere...hopefully the driver wouldnt take the brunt of those. i.e. When I see a rollcage thats been bent in a crash, usually means it's done it's job correctly.

long overdue.. this was submitted last year and basically ignored. This time the submissions had a lot more impotus and pointed out the failings of snz if they continue to defer what is a very important safety feature already widely used in USAC and Australia..
