I didn't pick up from your original post that you were doing this as a business, I thought you were doing it for home use. My mistake there and changes a lot of things.
The problem I found with log lifts is you still have to roll them around TO the log lift. Smaller stuff, 20 - 34, it's not too bad, 34- and up it's about all you can do and hard for 2 guys if there are knot balls and such. We work up everything and most pieces are not the straight logs that a lot of guys here seem to be working with. For a true one man operation with no noodling or hand split to quarter there are only 2 options. the Bobcat type as shown or an overhead lift.
I went with the lift as we cut where it lays, backing down the tree length, throwing wood to the side. You can load the truck as you go, loading from both sides once you move. We normally just haul another day and just fill the truck while we're there to save on trip. Your operation would be different. Pushing out the back is the most efficient but with big stuff you have to pull it back again. That is why I went with wedge on ram, plus the overhead lift doesn't swing back as it splits. Once chunked, you can swing the hanger away and work up the chunks to size that are sitting on the swing tables. Here are some pics of one being worked up.
The Tempest I saw had outfeed out both sides, meaning 2 conveyors were needed. Very fast design but makes a lot of smalls if that is an issue for you. The Bob Cat type take a lot of room and you still have all the splits on the ground you have to work around. I guess you shove or pinch to pick up but that is a lot of time running a bigger motor to do a trivial job.
For how we work up wood I think I have the best option I could have. For you I just don't know. Mine goes a lot smoother and quicker with 2 guys and I'm not denying that. But, I CAN do it by myself if needed and that is what I was shooting for. The winch has a 30 ft reach to drag them to the splitter if needed. Normal thing with 2 guys is to get it down to where it is 1 man chunk size, Then the other guy starts winching/dragging another into position. Constant flow and that is what you want to get things done.
I don't believe most commercial guys noodle. It's wasted product and tends to make shorts when you do split them up. We all get chunks on the nastys but I'd be interested to here from any of you commercial guys on whether you noodle all your big ones. I'm just cutting for personal use and do not sell.
