Picked up one of the front axle assembly's at the auction .. now getting it home seems a slightly bigger challenge than I thought

I am only 2 km from the auction house and thought a couple of the boys, lift one end of the crate and drag it onto the trailer and off we go

But they state it weighs 300 kg .. so guessing that 3 of us cannot lift it onto a trailer ?? Maybe not ?? I have a block and tackle and could drag a frame down .. is that going to work ??
You advice on the following would be greatly received ...
So for those that have already acquired heavy parts what is the best way to get them home ? Okay solved ... They will Forklift onto my trailer ..
Did they help with a fork lift or something to load onto a trailer? Answer YES

Cheers ...
Update ..
Rang Frontline contact .. they have a fork lift and will work out how get it onto the trailer so 1st problem solved

Have a block and tackle, just need to get a frame to hook it on so I can get it off
