The slew sideways can be quite significant.


This is one scenario. Add greasy slime at the recovering vehicle's position and it can happen. Too much gusto or rapid regaining of grip can see the bogged vehicle inadvertently "going bush".

It's much harder to draw the example of the effect on a sloping beach recovery, however this is where I've seen more of the problem in practice.

All I really want is for others to end up with recovery provisions which should never let them down one day. I've witnessed this issue numerous times, and know you can't always re-rig to avoid it when you only have a corner to pull on... or from. However I'll time out on this one now to avoid sounding like I'm stamping my foot over it.

Over'n'out,

No problem, I can see what you mean now. This is actually similar to what I was saying above with the freedom of direction the equaliser gives. It allows the tow vehicle more give to maintain a line around ruts or boulders, etc.

But there would be similar examples where even an equaliser wouldn't help you, if the towing vehicle is further to the left, an equaliser wouldn't prevent the towed vehicle lurching to the left and into an obstacle. It is hard to snatch around corners.

You may be better off with a winch or a shovel and some maxtrax as a backup where snatching isn't possible.

Anyway, nothing wrong with sharing views on recovery technique.....

Re: No tow hooks? Front Recovery Soluition help

FWIW, my comments on a couple of points made above:
  1. Assuming little or no friction between the equalisation strap and the snatch strap loop, the tension in both legs of the equalisation strap will be the same, therefore the load on both hooks will be the same. In anything other than a straight pull, the angle of the load on the hooks will be slightly different but the load will still be the same.
  2. The Pajero has a monocoque body whereas traditional Toyota fourbies have a chassis. The statement that a Pajero's body is weaker than other Toyotas may well be true but then to infer that all monocoque bodies are weaker than chassis bodies is fallacious. Any body, whether monocoque or chassis, can be made as strong as the manufacturer wants it to be. Weight for weight, a monocoque body is stronger. That is why they are now so favoured and it's about time, my 1953 VW Beatle was monocoque.

Re: No tow hooks? Front Recovery Soluition help

On point 1, yes, if the snatch strap moves freely then the load should be 50/50 on the hooks. Depending on how short the Equaliser strap is the force on the recovery point can be more than half the force of a single strap. So a 1,000kg snatch could have an effective 700kg force at each recovery point, if your ES is too short. It would also have the effect of pinching the front end together.

True!

BTW, my equaliser strap just arrived from JustStraps. Now to wait for the Chief hooks.

Re: No tow hooks? Front Recovery Soluition help

I got bored today and did a bit of photoshopping of a prerunner with integrated hooks I'd like to fit, if someone made it. It is loosely based on the RRO prerunner, but extends to cover the washer bottle and air compressor.

I guess you would also want a bit of rubber trim to run around the exposed edge of the bumper and hide the clip holes. Another problem is that the MY14 bumper cuts a bit higher than the 2011-13 models, but perhaps there could be some adjustment on height at the fittings.

I've been running the same idea through my head for a while now. I think the current designs around are virtually pointless as they fail to address more than half the vulnerability issue.

As it stands, at least leaving the plastic lower skirt on you're not driving about with your pants half down! It might cost money to replace the Tupperware, but at least insurance would pay for it if the damage warranted.

My thoughts are to shape big tube as per the detail line, so it sits over the exposed slots all the way to the edge. Yes it'd project upwards of the top mounting point a bit, but if you hit it that hard you'd have more to worry about!

Cheers,
Steve

Re: No tow hooks? Front Recovery Soluition help

Yeah, I'm use to have a decent approach angle on the cruiser, with the factory bull bar. But I've seen my mate's navara do a grading job on some tracks we go on, particularly soft sand. Trying to avoid that, and like you say, I don't really want to be driving with nothing covering the bottom of the radiator and these other bits.

I'm a bit surprised mopar haven't done something here, they have the rock rails and other skid plates.

edit: maybe Chief Products will deliver the goods.

Navaras / Pathys with genuine bar work fitted over the front have the most awful approach angle. I'll put a couple of bucks on it having one of those!

Re: No tow hooks? Front Recovery Soluition help

As some of you seem to have spare time - here is a little quiz.

Attached is a photo that shows a nice recovery point and a steel bash plate. Gold star for the person who can identify this hard core off road beast. Oh - there is another similar recovery point on the passanger side too.

Dunno about "nice"...

... I've got some great photos of that style of attachment point in less than ideal working condition.

However I'm stumped on what it's attached to. The plate in the lower LHS of the shot has me stumped. Is that part of a bullbar GM?

Yes... I have loads of time

Cheers,
Steve
