charlie,

 

theese are the winch chocks we use at work for soft ground they work fairly well. WINCH CHALLENGE WHEEL CHOCKS ( 1 PAIR ) on eBay (end time 26-Nov-10 14:48:14 GMT)

 

Wow, those ones look like they're on steroids compaired to my wussy ones

Good thread , lots of useful stuff, suprised no one has mentioned ground anchors. A very handy tool. Re the vehichle damage I put the strop round the rear of the chassis rather than the towbar on the hairy stuff.

Also its handy for re-routing the pull if there are no handy trees.

Just re-read B101's post and he pretty much nails it.

david, you have left very little room for movement in your vehicle positioning, lets say you dragged the jeep forward only 1m, you are then in a sticky wicket as you guys say, if rope length was the issue fair enough, but always carry extra strops, ropes, shackles with you.

Those chalks are ok for tarmac but on soft ground i wouldnt, going by the front of the chalks and the raised dirt the vehicle has shifted a bit.

 

That shot shows the landy after sliding a meter or so, whilst the chocks were on the back set

She held firm, once we changed them round to the front.

 

You're right regarding these particular chocks Stevie, there from Nelly (Denka platform) which is not specifically designed for off road.

Though we have used them a few times with no great dramas.

 

Will look into getting a set like the ones Matt linked to earlier

 

 

 

Any one willing to recomend a good training provider for Lantra 4x4 Winching?

oh and contry to popular belief even fibre winch ropes recoil!

 

when skidding timber out last year (?) a timberwolf 150 got in the way of a recoiling rope after the redirect pullys sling snapped, the force skidded the chipper 10ft sideways across grass, mudgaurd and tail light demolished

i done my professional offroad drivers course, and winching and recovery course with Venture 4x4, three holes, wisbech, they were really good 5 years ago!

the weakest link is usually how the winch is attached to the vehicle

David,

 

once upon a time thoose chocks were a genuine Land Rover accessory I will try and find the book I have at work which is a genuine Land Rover book and see if it has the part no's for the chocks.

they were sold by FW (part of Superwinch now) for there FW525 etc, the chain goes over the bumper.

 

the best off-road chocks were very like that but they had another ~1ft out in front with 2 extra spade lugs and folded flat in just the same way, they also had a loop so you could chain/strap the rear chocks to the front chocks

 

that said chocks put all sorts of forces into the radius arms and trailing links and that’s not to mention the forces placed on the king-pins or track-rod etc!

They were the best, but were both heavy and expensive new. I seem to recall that the Rover part no was 583590.

 

I have been on the lookout for a set for some time, but they are rare as hen's teeth and when they do come up now they're very pricey (mind you I did think £250 was a bit steep, but perhaps that's what they're worth now). If anyone here has a pair for sale, please PM me!

[b101uk]

Yes I seam to recall them being ~£250 new back in 1985.

 

That said they would be easy enough to knock up for a lot less money including galvanising and with a little extra thought they could double up as bridging ladders, but then if I wanted a set I would make them rather than buy them at that price, but they would be the better longer type which I have a CAD modal of
