One of my ongoing projects involves moving furniture-sized rocks with a pulley/cable system. Years ago I acquired a heavy duty (supposedly) military-surplus pulley. It incorporated an ingenious latch system to allow a quick insertion of the cable. Tip the big hook 90 degrees to unlatch a link, drop the cable in and reverse the process to use the system.
Recently I needed to get a second pulley and ended up on Amazon for the 30 ton snatch block shown here. It does what the previous one did but with a much simpler mechanism, using just three parts (one used twice) and a circlip. I think it's brilliant, but maybe I just impress easily.

This is not meant to be a negative comment at all, but is there anything Vevor won't put their name on? You could probably outfit your entire life with Vevor products. I have two Vevor electric motors I got from amazon and am happy with them...they were maybe 60% of the cost of an equivalent Harbor Freight branded motor (my only option other than Grainger for an OTC motor).
But it is funny: https://www.amazon.com/VEVOR/s?k=VEVOR
The swing sides idea is really clever, as long as there's no - or very little - rattle room between the two sides. Nyloc nuts ahoy! D.
Do you come quietly by night, move people's big rocks, surveille their property until you see that they've put the rocks back where they had them, and then move them again? Over and over, for years?
That was my hobby too, until I got shot.

I can’t say.
