I guess we only have photos as guides as to how a tank on this trailer would be secured, unless someone can come up with a manual for this vehicle which stated how it would be secured, or an account by someone who actually has loaded and driven one can be found.
(Though not specific to this vehicle), the humble wooden chock was in common use to prevent vehicle movement, then and decades later. Dozens of wartime pictures show that wooden chocks were the most common way to secure german armour and vehicles on freight wagons, its much less common to see chains, ropes or cables seen to be in use. Its interesting that only nails were used to prevent a large heavy vehicle from movement, and the forces exerted on loads during train movement could be considerable, due to a 'concertina effect'.
When I was a railway man we would place a humble wooden chock on the rail and kick it in to wedge into the space where the locomotive wheel meets the rail. This was used to secure 100 tonne locomotives. Yes they had a handbrake on as well, but the chock was an extra precaution that was mandatory when stabling a locomotive. Obviously no nails or other means were used to hold the chock as it was wedged between a flat steel rail and a the curve of the steel wheel.
Is it possible that wooden chocks wedged in the right place might also help prevent a load moving on a trailer.
Just my thoughts, for what its worth
(great looking build I'd like to add)
