Whopee! I can fit a 90kg anchor! Just kidding but with a bit of guidance I think you have helped me answer my own question :-)
You do need to consider the situation where all your chain is out and you drag into deep water. In this situation the winch will be required to lift all the chain and and anchor.
This is why most winch manufacturers recommend using the total weight of the ground tackle. You also need to consider the losses associated with turning the chain 90 degrees over the bow roller and friction etc.
This link suggest the maximium pull is 1000Kg which is quite a beefy winch, but worryingly they recommend it for a boat size 34-42 feet.!

Most winches rated for a working load of 120kg have a maximium pull of about 1000 lb
I found this link
Products | WINDLASSES AND CAPSTANS | WINDLASSES - VERTICAL AXE | Antares
Which seems to confirm the details.
So I am a bit puzzled exactly how big your winch is. Perhaps someone with the same winch can confirm how it performs in real life.
Most of the weight is in the chain therefore the chain length is therefore important. The length of chain needed is more dependent on the depth
of water you will be anchoring
It may be worth starting a new thread along the lines of "how much chain do I need for the xxxxx"
If you planning on cruising many different areas something like 100m is good to have.
