Thanks for that

I’ve looked at a few videos and have a snatch block. However can’t find any in relation to advantage on my unique purpose. As they are all for increasing power to move the vehicle. When I want the vehicle to move something.

I can see there is something here I’m not understanding and some pulling technique. By any chance do you know a video or link that can show me how to reduce pull on car or stop it sliding forward please?

Its simple at the moment you are using the winch power to move the post and the only anchor point is the car it then reaches a certain point and starts to move the car
If you use a snatch block attached to the post and anchor the end of the cable to a tree.
when you apply the same amount of force to the post the anchoring force will be spread 50% against the car and 50% against the tree which means you can use twice the power on the post before the car starts to slip.

Aaaahhhhhh now I understand!

Thank you this is perfect. I’ll whack one of my big steel stakes in the ground then there’s no trees. And pull it out after.

I’m thinking of using the snatch block on a 1 meter high A frame of staffolding for pulling stakes out vertically also. Do you think this would work as good as I imagine?

That will work.

You can also use a spare wheel next to the post the the rope going over it.
I would see if there are any winch training courses you can go on I did one a few years ago and found it very helpful.

Saying that, I may as well just put the stake under the tow bar and chain it!

Pretty much what I was doing previously. Winch with steel hoops bolted to the back fixture points... stake through either one whacked in deep. Backup chain in case of snapping. Winch sitting ground level with a dolly bolted to the bottom of marquee pole. Then pull inwards mechanically while pushing pole top up manually.

So the advantage of my new winch is space and energy saving. Safer rope. But not time saving IF/WHEN there’s no near by tree/anchor point.

Unless I figure a way of either reversing the car in special programs maybe and low range? To fight the tug on grass?

Or use bricks/grips/chocks in front of the wheels instead of the burden of whacking stakes in and pulling them out. Which is what I ultimately wanted to do not have to add anchorage.

Also the new tent requires doing 2-3 times now as it’s bigger. So vital I get the right way about it

Thanks I understand more now definitely

Hi all

Just a question please

I’m now wiring in a jib crane (12v 500kg winch bolted on to a swivelling steel crane arm)

I got some 10mm2 cable to run from the battery, under the body towards the back, so I could have an Anderson plug along side the electrical plug for the trailer. Then another Anderson clip wired in from the a frame, under the trailer, and another Anderson plug. Then the detachable crane have a plug and fixture points. (So it can be bolted on and used to lift marquee panel storage bags off and on the trailer.

But upon trying to wire, I’m finding it hard to get a clean run for the wire and it didn’t feel like a good installation!!!

So, my question is:

Can I make a plug that uses the second electrical supply socket on the D3? Or remove the spare car plug, and use the wires to fit an Anderson plug? Or use the plug type that the D3 has already.. but on the cranes wiring side, at the point of hitching?

I’m thinking if there’s a second power socket already installed on my car, then surely it’s wise to use this and keep it neat. Instead of adding another line.

Thanks I’m advance

I think I saw theres a difference in voltage on the two hitch plugs. Hoping the spare is 12v or i could use just a few of the pins in the plug to get what I need maybe!

10mm2 cable is not heavy enough for that length of run.
I used 35mm2 cable for my trailer mounted winch, i ran it down along the chassis on the passenger side in plastic conduit.
I only ran the positive and connect the negative side direct to the chassis, i know this goes against what most winch manufacturers recomend but it has worked very well for me for many years.
I then have an anderson plug bolted to the towbar and use a short extention when i want to use the winch.

Hi are you ruling out the modification of the vehicles second towbar power output?

Also, I’m not great with wiring knowledge.. does your reply mean that the negative is just needing earthing? And the positive red is all that’s needed to be run from battery to rear end?

Also, I have an isolation switch on the negative wire on my new front winch. But the winch still works when it’s switched off and the red plastic key removed. Does this mean the switch is faulty or at I doing something wrong please?

The pins in the tow electrics sockets are only rated a 15 amps so are not heavy enough.

The cabling needs to be capable of carrying at least 1.5 time the current for short lengths or very short usage times for longer runs or where the demand for power is over a longer period the cabling needs to be rated at 2 or 3 times the current draw.

With your isolator switch it needs to go in the positive cable not the negative, you have run a negative cable to the winch which usually bolts to the frame of the winch but the winch will also be bolted to the chassis which also connects it to the negative side of the battery. So when you turn the switch off the winch is still able to make the circuit back through the chassis.

Ah ok. Thanks.

So 35mm2 red cable, wired from the battery up to the tow bar. Then Anderson plug. Then Anderson plug and use the original 10mm2 wiring from the a frame onwards to crane. And connect the black to say solder it to the trailer frame somewhere hidden?

Does that sound ok?

Or run black and red from battery?

you can't conenct the black to the trailer frame.
It must goto the car through a connector.

Ok so I could use say a crocodile clip on the negative 10mm2 crane cable to be touching the car chassis.

Saves me buying as much expensive cable!

Cheers

The way i would do it.

Run a length of 35mm2 cable to a 350a mega fuse mounted under the bonnet from there run 35mm2 cable under the vehicle to an anderson plug mounted on the towbar for the positive connection, run a length of 35mm2 from the negative side of the anderson plug and connect to a good clean part of the vehicle chassis.

On your crane mount an anderson plug near the base with both positive an negative wires connected. Then make an extention lead using 35mm2 cable with an anderson plug on each end.

When you want to use the crane just connect the extension lead to the crane and the vehicle and you will have power

I'm very worried about your wiring. The isolation switch/solenoid should always be in the positive line. The winch motor is possibly earthed through the mountings/chassis to the battery so disconnecting the big earth wire to the battery will have no effect whatsoever. Also, what is the rating on the switch you're using? Most kill switches with the plastic keys are only rated to 125A continuous, you'll draw up to 400A with a winch.
