This shouldn’t be a problem for a top beam frame. The only thing I’d really be worried about would be any play in the chain links, and any play in the linkage system. The latter shouldn’t be an issue, although if there is any slop in the system, the top of the machine is where we would notice them the most. I remember seeing posts that mentioned that there could be play in the chain links, which would obviously add up across a longer span of chain. Is this actually an issue or am I worrying over nothing?
That’s a very good point. So ultimately it may be the best idea to reduce the sled weight to prevent motor stall.
I wanted to make sure this is something we are thinking about as we go into experimenting with a longer top beam. I know that I wouldn’t think too much about it, go through all the effort of setting up a 12 or 14 foot beam, and then wonder why my motors can’t lift the sled. Admittedly, this probably affects me more than others, since I have a 40 lb sled currently.
