Looks just like my trolly setup. same hf winch even!
Nice!. Figured my simple light weight design would get others to setup same!
I used 2 pair of 440 lb trolleys rolls smooth Just noisy .
I have been adding track in different locations on my ceiling to use for lifting anything 400 lbs or less. "AWSOME " one of more useful shop upgrades. back truck in and trolley over and lift out 250lb sheet goods with a c clamp, and no help.
Just need to keep in mind its for moving vise, pallets, 4th axis tools around and bulky light material .
