I dont know if hydraulic lift tandems go back that far - but they've existed in the dump world for a long time of course.

Welp AI taught me something.....

Lift axles, in general, were in use by the
early 1940s, initially utilizing mechanical devices before quickly transitioning to hydraulic systems.
Regarding specific advancements in tandem axle technology:

1957: The liftable tandem drive axle was invented by Finnish truck manufacturer Vanajan Autotehdas.
Early 1960s: Non-ground bearing hydraulic detachable gooseneck trailers, which utilize advanced hydraulic lifting/lowering systems, were introduced around 1962.
Modern Hydraulic/Air Lift: While early systems were hydraulic, modern, common, computer-controlled "airlift" axles that automatically lower when weight limits are reached became standard in later years, often referred to as "pusher" or "tag"
