Hey Guys I may be able to help you out with your problems getting vehicles in your shop even in extreme cold weather.
Operating a shop in Fairbanks Alaska and temperatures down below -50 below at times.
We built a 10' push bar 2" square this bar has frame hooks on one end and a regular chain hook on the other end.
We use a 4 wheel drive to push and pull vehicles around the lot and into the bays. My service truck has a chain mounted
to the front of the frame of the truck hanging down far enough to attach the hook bolted to the bar and like I said
the other end has body hooks that attach to the under side of most vehicles with frame holes.
I will attempt to post a video showing how this works later on today. I will also attempt to post pictures.
