question JATE rigging for a Land Rovers 1970s vintage

Before I opened the thread I thought you had mistyped JATO and was intruiged.

My guess would be that the hook on the chain would be a "Clevis Hook" that has a narrow slot that locks in between tow links like this type.

The 3/8 inch measurement refers to the dianeter of the "Wire" the chain is made from.

Could be fun to fit a Landy with JATO. :cool2: For those who may not be aware, JATO- Jet Assisted Take Off. JATE, Joint Air Transport Establishment. The purpose of which was - The study , development and testing of service techniques and equipment for airborne assualt and air transportable operations. In 1998 it became the Joint Air Delivery , Test and Evaluation Unit.

l have been to my unit this morning because for years l have had a box that contains[ Securing Airlift Equipment ] that

has been with me since the late sixties in it are the chains for use on MSP,s [MEDIUM STRESS PLATFORM] and for heli

lift of vehicles there seems to be two types of chain heavy and light the heavy is ten feet long the light is three feet long

but the hook design is the same see attachment

REGARDS WALLY

The orange paint = livery of Kuplex , it is a older style 'Grab Hook' that would be used on a lashing / winching chain - not on a lifting chain. A lifting chain for shortening would use a similar component but designed for the application of shortening - a 'Clutch' normally fitted at the master ring/ loop. The silver one looks like a similar Pewag manuf. component.

I first heard mention of a JATE on a Land Rover when the U shackle loops were first fitted on the Defender chassis , the name originating from the later named JATEU - and it stuck. (IIRC = Joint Air Test and Evaluation Unit)

Regarding the original query - you seem to be asking for specifics , but don't describe the specifics of the actual vehicle .

-----------------

With Lightweight photographs - you will see a timber often 2" x 2" or 2" x 1" batten bolted to the rad. grille mesh , Kuplex chains 4-leg shortening clutches & position fixed with tie-wraps , wrapped with hessian - even undated pics. of early L'wt. Many early Lightweights had rope 'burns' on the bonnet front edge , my understanding is that the original helo-lift was using spreader beams with ropes (no chains) , the four attachment ropes had QR (quick-release) shackles , I don't think I have ever seen a in-service photograph of this arrangement. However several years ago , somebody on eBay sold several of these lifting kits , asking £40 - I wish now I had purchased..

Thank you for that as the chains are colour coded yellow green orange blue red and are of the same design may be some one could tell me there purpose l know some are for lashing down vehicles on MSP.S as are the quick release turn buckles

as l seen them used to rig a platform

Interesting stuff.

I have a chain identical to the 'light' chain you described but with a yellow hook. A very useful bit of kit - I wish I had more of them.

Paint colour used by manufacturer is not always a good guide on new tackle , however much of the yellow painted stuff of this type that is specifically for fishing boat gear. Going by the chandlers prices I have seen - can't be the higher grade steel lifting tackle component ,,

Hi Robin, I was previously OC Aerial Delivery Section JATE and one of my sections carried out trial rigging and produced the final rigging scheme. Overall design was a REME responsibility so there may be copies of old rigging schemes in the REME Museum archive..

I wasn't intimately involved in the rigging process but it is a complex mix of shock struts, honeycomb cardboard and securing chains. Most of the impact was taken by the wooden shock struts which forced a steel mandrel down a steel tube. The cardboard honeycomb took around 20 percent of the shock and the vehicle suspension took the last 20 percent or so.

Fro memory the chains were taped with black tape which was extensively used on all rigging schemes. The vehicle had to be well secured to the platform which nearly turns upside down on initial extraction.

The wire was a figure of 8 loop as I recall which went around bobbins on the outside edge of the platform.

My memory is very hazy so I would contact the REME Museum in the first instance.

I am looking for very specific details so I ca as near as possible recreate proper lifting gear

 

From what I can see there was a chain with a hook that grabbed back onto the chain at the vehicle end, how did that hook stay locked on? How long was the chain portion, what was the chain size, what is the hook design?

 

At some point the chain transitions to what looks like a poly covered wire, how does the changes take place?

 

How does the wire terminate and onto what?

 

Please and many many thank yous to anyone who can help.

I understand Robin is wishing to re-create actual lifting tackle for Helo-Lift (that is a practicable proposition) - not delivery by MSP , I suppose with MSP - if it survived and drove off - it would then be cleared of all tackle etc.

With Helo-Lift - actually some of the better photographs of tackle installed on L'wt - they are coming ashore from Landing craft , I suppose the tackle was in-situ for the return trip ?

Thank you all for the replies, loads of info there for me to digest.

I am amazed that the hooks do not have some kind of positive lock mechanism to hold them against the links of the chain, that still boggles my mind.

As Ruxy pointed out I am going to recreate a helo lift but the MSP info is valuable for others I am sure.

So far nothing about the chain to cable transition or cable to master link.

Looks like the positive lock for the hooks was Tyewraps (other makes are of course available) with the chains wrapped in black bodge tape. Yes that's the Mob I remember...:-D

So it should be easier to replicate as the "specialist" cable ties and bodge tape are available......

I remember driving a BV202 up from Odiham to Let Jate play with it and sort out the rigging, went the past the peace camp on the A38 (Sorry dear, you should have been quicker getting out the way). Were you there then Doug? (Not the peace camp).

Lots of luck with it Robin!

Patience as always seems to pay off.

There is currently on ebay in the uk an advert which shows 4 leg helicopter lifting chain.

The imges below show a close likeness to what I am told would have been used to lift a Land Rover in NI in the 1970s, specifically the Land Rover wheelbarrow EOD portee and the fish fryer jamming trailer.

The cost of sending these over from the UK will be hideous, who knows what friends I my have left or people who might owe me something.

Anyway, here are the images and I will see what I may be able to source, if I could get the hooks locally and the funny pairs of plates that transition from chain to cable I may have a winner.

I think a visit to my local Air Force airborne transport school is in order now I have these pictures.

The Land Rover wheelbarrow EOD portee and the fish fryer jamming trailer stationed at Bessbrook Mill (Tac HQ, South Armagh) had what appeared to be these chains attached at all times as I never saw them without. The bright green cables were especially memorable standing out against the matt green and black camo. The Land Rover was really stripped down without much in the way of bodywork, no front wings, or windshield as I recall.

Rob,

getting a comment like that on this subject completely voluntarily without telling you why I am so keen is brilliant and makes all of this so worth while.

Thank you, I will dig deeper.

Your photographs , look at the tag. SWL capacity (Defender more than Series) , the 'hooks' are shortening clutches - getting close to some applications.

Have a look here (I think it will bring up all pages for info. on this subject - however - I would need more time , possibly I can see detail better with a glass) , the MJC Lightweight 1/2 ton book pages 140 on . In the yard the EOD L'wt has no tackle , it has no standard front & rear chassis lifting points.

Interesting , the EOD photograph in the book show a EOD L'wt in the field service (1981) , my original hardback & softback editions don't show this. I spoke to Mark recently about the very few difference with the latest edition (softback) - this photograph inclusion was not mentioned. I have been intending to buy the latest edition , however there seems to be many new earlier softback editions on sale still - so I need to make precise enquiry as to the date of print before purchase..
