Another of my few remaining tools and equipment I made long ago.
Back in the late 80's to early 90's we needed a headache rack on one of our trucks this was what I did
the headache rack was made with locking bars for the chains binders and below them there was a locking rack for straps. Since the truck had a long wheel base I mounted it on a drone which served as a platform to stand on for retrieving and replacing the load binding equipment as well as a mount for the tool box. in the tool box I made a tray which could be lifted up and clear of the box allowing clear access to the bottom of the box
