I am installing D-rings on the floor of my trailer which will connect to the frame for max strength. When loaded on the trailer I want to secure my tractor from tipping so I will put chains around the axles and secure them to the D-rings. My question is how to tension the chains given the short distance from the axle to the D-ring. I can't measure this distance right now because the tractor is in the shop but the working room is probably less than 18". (I am thinking I want a 5000 lb WLL tie-down; I trust load binders more than ratchet straps.) The tractor is a 1958 Ford 641. My searches for chain binders don't give the lengths. I would like to have my trailer modified before I go to pick it up. Thanks.
