Of course, there would need to be an on-off switch. But DC? Was that just for the controls?No sir its DC
Yes each one is left right, fed bkwd, up down as you say, the chain only is power on and off

No sir, dc cranes.....makes it more interesting
I've just been on the phone to a friend who spent most of his life mending TVs, radios, etc. He had his own repair shop in west London. He thinks it most likely that the electricity supply in the area was DC, hence the crane being DC. Parts of west London were still on DC in the 1960s, being converted to AC street by street. Edison lost out on DC transmission, because there is less line droppage with AC. Why did you say the cranes being DC "makes it more interesting"?
Try and get someone to fix em and you'll find out
