The thread in my pedal crank has given up so need to replace my chainset. I've got all the right equipment but finding it completely immovable (I'm using a bigger wrench than the one in the picture now).
Any tips?

You need two wrenches on the crank extractor.
double check that it’s threaded in correctly. the extraction threads are really fine and easy to cross-thread, and it will make your task here A LOT harder if they strip. there should be a smooth, consistent resistance when threading in the extractor tool. a sudden rise in resistance signals cross-threading.
to get better leverage, angle the crank and wrench like an upside-down V. grab each arm and push together, using your chest muscles. try to get the arms as close to each other as possible.
Take the extractor tool out completely and make sure there isn’t a washer in there, and that the end of your tool is small enough to actually go in the square hole to press on the spindle,
If everything is engaging properly you just need more leverage
As long as the extractor is screwed in properly and it looks to be what you are missing is leverage. If the crank has been there a while it’s going to just laugh at the short spanner you have there you will need something much longer so if you have something like a short piece of tube that will fit over the handle try again. Apply steady pressure and it will give in
I just had a crankset removal problem and I had to get a helper so I could get maximum leverage. I also wear work gloves from a fear of cut knuckles.
You’ll have to figure out the best leverage position. Typically that the crank arm and the tool handle in-line.
Make sure the pusher end has a smaller diameter than the hole in the crank arm.
Some less expensive removal tools have a large diameter pusher.
