Question about the Andymark climber in a box. After doing some research and looking at blueprints, we decided that it is too long for our goals. But, there are no internal blueprints. Does anybody know if we could cut it down to make it shorter in the middle or if that’s even possible?

You can. My team is installing our recently modified climber this weekend.

Just make sure to cut down all of the stages (two or three) the same amount.

Also note that for a two-stage climber, this will shorten your minimum height by a factor of one, but will shorten your max height by a factor of two.

ok thank you so much, I will do that

We also need to cut our climber and don’t want to mess it up since we only have a limited amount of material. I want to make sure I understand what you are saying here.

If we cut say 12" off of the stages, then we reduced our starting height by 12 inches, but reduce our max length by 24, right?

yes, that is correct. we just finished our climber and we considered that. Also, keep in mind the angle your climber will sit at to consider the net height. You’ll have to do trig calculations for that.

We are planning to mount vertically. The math is just throwing me off because it doesn’t seem that the length of the tube I am calculating would get us to the height we want.

I’m getting that we need to cut 20 inches off of the tubes. Which, based on the drawing on Andymark, would get us a starting height of 17.5ish and a total length of 46ish which we’d have to limit. That math just doesn’t seem to be matching to me

How many pieces of tubing are there in one of your climbers?

We are doing a 2 stage, so 3 total.

yeah in that case your math sounds about right. With a two stage climber your extended length ends up being a little under three times the starting length. 17.5" times 3 is 52.5" and 6.5" sounds like enough to compensate for motor mount/overlaps/not starting quite on the ground.

I’m just having a hard time seeing how cutting the stages down to 10 inches will get us over 40 inches in height.

~~10 inch stages won’t reach 40 inches.~~ How high off the ground are you mounting the bottom of your climber? If you can get it lower that will let you have longer stages for the same starting height and therefore more extension.

@Christopher149 's comment made me think about this a little bit more. From 17.5" starting height you’ll get no more than an additional 20" and it’s really a bit less than that since you have overlap so it’ll reach somewhere under 37.5"

With the top of the collapsed climber over 20 inches off the ground?

We will be 3.75" from the floor to the bottom of the climber

Okay yeah that probably won’t get you a lot then. I think I was underestimating the amount of space eaten up by the overlap so I went and did the math out using Andymark’s CAD model and ended up at 33.05" as a max height with a starting height of 21.25". I think if you cut 15" off of each tube you could reach about 46" with a starting height of 26.25". Sorry if I caused any confusion. I did a bad job of estimating how much space is lost on the bottom of the climber.

Calculations:

Measuring on the CAD model I got a total of 51.8" of extension (25.9" on each stage). The entire model is 37.5" tall to the top of the hook so starting from 3.75" I got up to a starting height of 41.25" and a final height of 93.05" Taking 20" off each of the three pieces of tubing I got to a starting height of 21.25" and a final height of 33.05".

To try to calculate how much tube to cut off to still be able to reach to 46" I took the final height from above (93.05") and subtracted 46" meaning 47.05" can be removed. I divided this by 3 to get to 15" off each of the three tubes and then subtracted this from the starting height above (41.25") to get to a starting height of 26.25"

They’re very helpful when you’re only looking for dimensions and don’t necessarily need to sort through a CAD file.(https://cdn.andymark.com/media/W1siZiIsIjIwMjIvMDEvMTkvMTUvMzIvMzEvZWYxNDgwMjItNzdkZS00MmM4LTliNDktYzFiN2Y2ZDU3YWIyL2FtLTQ2NjcgMSBTdGFnZSBDbGltYmVyIGluIGEgQm94LnBkZiJdXQ/am-4667%201%20Stage%20Climber%20in%20a%20Box.pdf?sha=6050c6ebe68fa7bd)

Thanks. I had the drawing already, but just wanted to double check before cutting.
