Tow loops - wire rope!


Recommended Posts

Anyone noticed this in the 2017 Blue Book?

 

Q 19.1.3.
(a) There must be substantial towing eyes securely
fixed to the main structure of the vehicle, front
and rear, within the confines of the body to
enable the vehicle to be moved. Cars of periods
A to F and single seater racing cars are exempt
from this requirement subject to a suitable towing
point being clearly identified. Towing eyes must
have a minimum internal diameter of 60mm.
Towing eyes/towing points should be painted a
contrasting bright colour (dayglo red, orange or
yellow, marked with an arrow and the word “tow”.
(B) The following configuration and specifications are
strongly recommended:
Vehicles to be equipped with two front and two
rear towing eyes positioned equally either side of
the longitudinal center line.
The towing eyes to be made of steel wire rope of
at least 6mm diameter with a 6x19 wire core.
Each towing eye to have a breaking-strain of at
least 2 tons and allow the passage of a cylinder
with a diameter of 60mm.
The towing eye to be fixed to a structural part of
the chassis with a minimum of M10 (Grade 8.8)
fixings, the inner part must be flexible in order for
the towing eye to be retracted inside the bodywork
profile.
Towing eyes should be situated 25mm forward of
the adjacent bodywork with clearance of 100mm
above and below to enable recovery crews to
attach straps and shackles.
A “pull-cord” to be attached to the towing eye to
enable the marshals to access it. The end
attached to the chassis may be either ‘thimble’ or
‘open-loop’ style.

 

Apparently it was an alternative last year, but "strongly recommended" this.

Probably compulsory next.

Many of this years racers have a neatly folded strap complete with integral stitched large dia 60mm steel ring material secured with a tie wrap against the front of the cars, sounds like a development of this being promoted.

Am I right in thinking that for the TR sprints etc. One doesn't need to upgrade from webbing tow loops to these wire ones?

I refer the Honourable Member to S.10.1.15,

"It is recommended that suitable towing point(s)

on all cars shall be clearly identified, and suitably
marked, using a contrasting bright colour, accessible
from the front and rear."
