the concret pipe trap is indeed a heavy thing and you need a machine to set it on its place. but with a little bit of maintenance it will do its work for decades. the concrete pipe trap was invented in germany in the early 1980s when hunters notice what a fox was allways doing. its common to have drainage ditches on the fields and where a farm track is crossing such a ditch you have a conrete pipe under this crossing to make a way for the water. it looks like this:

many of this ditches are only full with water in spring but the rest of the year more or less dry.
mister fox makes the patrol early in the morning and late in the evening every day and hunter see he was allways taking the way through such a concrete pipe if it was on his way.
so the idea was born to set such pipes for trapping and it became a great success not only for fox but other like racoon, marten, badger, racoon dog too.

the trap is great but maybe a little bit overengineering

here you see how to bring the game into the abfangkorb https://www.youtube.com/watch?v=AT8X5mNL4Kk

abfangen is german hunter language for killing, so simple

the most ingenious trap is imho, the danish crow trap

you see it here, very simple

you give a bait into the trap, maybe corn or other things the crows like. its easy to jump into the trap for the crow through the openings between the wood but its impossible to fly up again because the opening is to small for this. if the the first crow is trapped inside it will start a lot of noise that attract other crows who jump into the trap one after the other.
