So my team is making a DR4B lift for the first time. Are there any tips on how you guys would recommend powering it, mounting it, and keeping it structurally secure? That’s what I feel the hardest parts of the DR4B lift would be, and I would appreciate any tips you guys have. Also, what is the best…

Yes that will definitely help. What about mounting it to the base? Any specific way to mount it that works very well?

Ideally with either a standoff or a half c-channel that forms a triangle between the tower and the drivetrain.

ah yes of course, the all mighty triangle is the obvious choice.

Power the lift from the center. Sounds like a no brained but I didn’t do this in ITZ and I would not wish that pain upon some one else

So would you just directly connect the motors to the gears in the middle of the lift? I would imagine you would want some type of gear ratio to increase the torque wouldn’t you?

It should be powering a pinion gear meshed to the gear connected to the bottom linkage.

I should’ve been more clear, just look at any worlds level ITZ reveal and you’ll see. They power their oft from the center segment rather than the bottom and center segment. Generally, 1:5 (torque) works well with two motors and v5. However, I would use 1:7 (torque) because of the heavy load this ye…

[image] 64540A: worlds level ITZ reveal Okay Thank you, I see how that works now. Just out of curiosity but has there been anyone who has gotten a higher torque ratio than that 1:7 on a DR4B lift?

You could, but don’t. You will be in for a world of suffering if you try to use a compound gear ratio on a DR4B.
