The issues are:
(1) lifting the logs
(2) supporting them as they are run through the bandsaw
You can combine the 2 or not. A motor lift/cherry picker will work to lift them and move them, but the wheels are a bit small. A pump lift table will work also and has the added advantage of adjustable height.
For the resaw setup I made, I use adjustable height roller supports.
These worker OK, but the rollers weren't really in use so ...
I then I made a jointer extension support by removing the rollers (easily done) with a 2 x 12" plank.
Get 4 elcheapo roller stands.
Remove the rollers and replace them with a 2" x 12" plank on either side of the table, assuming you have 4 stands. Under the plank you can "tack" additional support struts to support the plank if it sags. To remove the rollers from the stands just push in on the pin, it's springloaded, and the roller will pop out.
If you don't have 2 - 2 x12" planks just buy some at HD, use them, and return them the next day, "Sorry, I didn't need these...... any more"
