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
