attached are pictures
Edit: the last three pictures are uploaded at really low res. But the first two are reasonable quality… I recommend that you follow the link and actually look at the model. (You don’t have to download a program, you can look at it directly on the site)
I might consider making the first tower out of 5x c channel. it will give you less flex in the lift and the arm will move and turn with the chassis more than if it is just a 2x.
also doesn’t look like you have a full chassis, but making sure that the chassis doesn’t have too much flex where the tower attaches. it is going to make a big difference in how stable the actual arm is.
we put a 2x c channel toward the front of the chassis going from one side to the other and it made the lift a lot more solid because the flex was actually coming from the chassis, not the lift.
is the chain bar on the top of the lift designed to move skyrises from the autoloader to the base?
if so, how are you going to fit between them like that?
I feel like the back of the arm would hit the auto loader every time it tried to rise due to the swinging of the first 4 bar layer.
do you have it built yet? love to see it!
