In Nova Scotia, by the book, we have to have a separate chain with a binder at each corner of the machine along with a separate chain and binder for the bucket or an impliment. They are really truing to get haulers to use ratcheting chain binds and even heavy duty ratchet straps on smaller equipment. Longeer hauls are done by the book while short, community hauls usually get a couple of chains and binders.
I almost always use the tractive force of a skidsteer or tractor or backhoe to tighten the rear chains and will argue that I almost always end up being tighter than when using a chain bind. And I'm not talking about snow or ice covered trailer decks either.
