Elevator Help

I ordered these rollers for an elevator but I am unsure what is keeping the bars from falling inwards. Is there something I can buy to prevent that?!

This kind of system only really works when you have a rectangular elevator frame (254 in 2018, 1323 in 2018 and 2019 for example). You’ll need to have two uprights parallel to eachother on either side of the robot and then connect them at the top and the bottom with a horizontal beam. If you’re looking to build a single pillar elevator you’ll probably need to use a different product/solution to achieve your goals.

Thank you! I was planning on having two pillars but there is a mechanism in the center of the elevator so I could have a horizontal on the top but on the bottom I could only have it on the outermost bar that is fixed to the frame. Do you think that would be okay?

No offense, but I feel like you should’ve done more research regarding elevators. Just buying bearing blocks without knowing how to use them or how they work isn’t really a smart idea.

That being said, the product you linked seems to be really cool and simple. The bolts that hold the bearing blocks appear to prevent the bearing blocks from moving around.

There’s no way for you to tie the 1st stage frame together at the bottom? Even a supporting member about halfway down the length of the elevator would provide a huge amount of rigidity. I recommend you avoid building an elevator that is effectively U shaped with no support at the bottom. You’ll have issues all season long with your elevator frame falling out of the uprights because of the lack of support. Last year my former team dealt with a pretty similar issue and we never could get our elevator and scoring mechanism functioning properly. If your design absolutely critically relies on the bottom of the elevator being open you should look at REV Robotics’ lift kit. The V-bearings included in that kit constrain themselves on the elevator rails so you don’t need to connect the bottom of the moving stage. Apologies if I’ve misunderstood your design ideas.

Wow thank you so much for you advice! I didn’t even think of putting a bar half way down I will definitely try that!

No problem! Take a look at 1678’s CAD from the past two years. It might be helpful. If you need any more help with it feel free to PM me and I’ll do my best to assist!
