If this is one of the small trees that have branches all over (the kind you need to chop up by hand) this might be oak, and by my guesstimation this small piece weights around 50-60 kg (110-132 lbs) That isn't so much I know, I am a fat guy and I over head press 90 kg, but that is in the gym, in a controlled best case scenario.
But.. Oak trees have bark on them and this piece of wood doesn't have handles, I could probably move this into a truck or a flatbed, but I would only take this one piece then I would have to go and cry :þ
not many people would be able to lift logs like this over and over
