Hi guys,
I am building a winch for a client in Sweden. I wanted to share some pictures.
This is what it will look like when complete:
It can be equipped with electrical slipring and or fiber slipring.
I’ll post a video when I got it running.
Cheers,
E.
Superb !!
Wow, @etienne, that is quite impressive. Those anodized aluminum parts are huge! What is the upper part of the frame for? It looks like it has lights or cameras?
The upper part is for IP cameras and lights 
This way you can see whats happening on the drum and in the water.
Good looking winch!
Is that a stepper motor operated level wind on the top/front of the frame?
How much weight it is going to haul?
Hello,
It is a stepper motor + guide for CNC mahine. it can handle a surprising amount of side load.
The main BLDC drive can handle 22Nm. So top wrap will have theoretical 98Nm and bottom wrap 278Nm. Max speed is 200RPM but not sure if I will allow it to go this fast. I’ll have to test it when I get there. I was looking at another motor that could do 150Nm but it was a bit too heavy and I didn’t want to sacrifice too much tether.
This is not a load bearing winch. Its going to be strong enough to handle tether management but the break is electrical.
I went this way for several reasons:
So its not to launch and recover the ROV. For that I call sell a hoist + basket.
I also designed (not yet built) a latching system + bullet but that would be for bigger ROVs…
Cheers,
E.
Hello all,
I wanted to share with you the completed electrical winch.
Took me a while to tame the winch controller but I must admit I am very happy with the results.
Here is a small video:
For the next version I will be replacing the pelican style power controller to a rackmount version.
I will also add the coiler and IP cameras.
We also have a hand crank version with a lock lack mechanism at the top:
We were able to fit 2KM of 6mm fiber tether…
Cheers,
E.
awesome! Great video too
Thanks Marcus, I hate making those. I wished Rusty came to visit so I could trick him in shooting some videos for us
Looks pretty awesome! how much for one of these for 300m of tether?

Hi,
The winch details can be found here: http://www.deltarov.com/new/product/electrical-storage-winch/
That said I am making a revision for a motor with right angle gearbox with fail safe brake.
Cheers,
E.
