Motorized winch ...

[principedeleon]

Hey guys.. I have seen a couple of motorized winches and im trying to build a mechanical winch that uses a large sprockets and a gear box to multiply the pulling ratio .

I get the basic facts of how it works to make it pull but i just havent seen how does these winches reverse in the rope or wire in the drum.

So maybe someone here who haves one made could show me how could it be made .

I have seen a couple of them online but i cant notice how the reverse is built into the winch.

This a good example of what im looking to build .

Do you need to power reverse or just free spool out?
A heavy duty 3000lb boat winch with a brake and a chain saw motor would be a good combo with the right gears to really pull a load. Should be easy to mate up with a couple sprockets and a chain or belt.

For a 12vdc winch the polarity of the motor is reversed with a switch.

There isn't a reverse, just a brake on the gear drive winches - usually along with a friction driven belt from the motor that drives it. You pull the cable out by hand after disengaging the belt and the gears. So you have a handle for the belt and a second handle that separates the drive gears. Basically what I had was just like the one you have pictured. Here's a video of it, but I think you've seen it already.

Mike..I want to just free the spool out.

Russau.. Im planning on using a 3hp gas engine.

Reed..i thought about making a handle to tighten o loosing the belt power. But i didnt thought about having to loosing also the chain.

Thought it maybe had another mechanism that could maybe reverse or loosing it faster.

I would use some kind of a centrical clutch to spin the chain , maybe for a go cart or something similar .

Free spool out, power in and use the brake on the power in to slow the speed down as needed.

Winching isn't anything to take lightly - death is likely if you don't know what you are doing - may still happen even you do know what you are doing. Have someone show you the ropes before getting a winch. It sounds like you should buy a winch rather than build one. If running a winch is a dangerous thing then running a home built one is a hundred fold.

Have you asked the question do you NEED a winch or just want one. Most folks don't need one <---- Yuba guys this doesn't apply to you

If you do get one get the synthetic cable rather than the steel one, there is no reason these days to do other wise. Am Steel and the like is what you looking for.

If you really NEED one, have someone show you how to operate it and go to buy one you are looking for something like this

I totally agree with the brake statement , I thought he was looking for a way to tranfer power , and still be able to use the chain drive .

Hi Ratled & Reed .. Thanks for ya advices..im right now in a river that have been heavly mined and im trying to get into the more difficult part of the river to find more virgen ground. i have already started building the winch i have been trying to build a more stronger winch then the ones shown i believe so since i never seen one in person. i have in plan on using a plasma syntheic rope which is a bit stronger then the am steel. i also have in plan using a 3/4" rope with a smaller diameter sling for if anything breaks be the sling wire..

i have built the a disengage funcion and plan on loosing the belt from pully to slow the pull..But i didnt have in plan on building a brake because i couldnt capture it built in the pictures i have been able to download..

im also planning on building it with a larger engine like a 6.5HP engine with a 2:1 REDUCTION CLUTCH ..

i will post more pictures but for now these are what i have ..

Here are some Pictures of my build of my Trevs dredge / subbie which i use in deeper water..

Hello Everyone.. Dont let no one tell you you cant do it. i have build My Dredges and now My own Mechanical Winch. it could break in 3 pieces and be taking anywhere.

 

[Reed Lukens]

Looks like you need something to be able to disengage the motor. Usually they have a bit larger belt on the first set coming off the motor, with an idler pulley mounted on a bar that you can throw down on the first belt to engage, then throw up to disengage the motor from the winch. Maybe I'm just not seeing it

 

[Reed Lukens]

Here's our throw arm. You could push down hard on it if needed to move heavier boulders that were causing the belt to slip.

 

[Reed Lukens]

Then here's the arm thrown up with the extension rod slipped off and the motor shut down. This way you can pull out the cable a bit without completely disengaging the shaft.

Hi Reed, I did get to build a clutch system and also a way to desengage to the drum from the motor. The reason you didnt get to see it is because the belt i got it too small and there wasnt any play in between it. i also didnt install the Pulley Bar because i needed a 5/8" screw to set it in place. On Monday i would buy some washers to install the Drum Chain and try to complete it.

im interested in buying some synthetic rope online but with all the Plandemia i cant not buy anything online to get it shipped to my country.

here locally i could get wire rope or some polyester rope..
but even that is hard because most everything is closed.

Go with wire cable. It lasts a lot longer.
