I'm currently building a functional Lego escalator that is minifigure-scaled and with staircases transitioning from flat platform to stairwell. Here's my progress so far: escalator slope design But with the design of the staircases hopefully out of the way for now, I've come into an issue with the slope as it is seemingly improbable to build. I tried multiple iterations: technic bricks, technic beams, snot, … but there's only so much I can do on Mecabricks. I don't have the necessary bricks available at my disposal, nor does my local area has any retails which offers the Pick-a-Brick service, therefore I couldn't physically test this build out.

Is there any way of building a framework for this slope to hold up at a precise angle of 39.5 degrees? Preferably one that is legal or at least doesn't cause immense stress on the bricks, due to the technical nature of this build?

EDIT: Extra images for elaboration: Isometric perspective of escalator design Design of stair consists of 2 3M shafts, plate 1x2 with holder (vertical), and plate 1x1 with upright holder

I aim to have this escalator to be roughly 4 bricks in width and its height will be dependent on how tall a story might be (probably 9 bricks tall).

I don't intend to use the new dedicated escalator piece because I want to design an escalator that is flat at the base and transition into a moving stairwell then back into a flat platform at the top (and vice versa). Basically something of this complexity , but at a minifigure scale.

EDIT 2: These are the results I yielded when I tried hinge pieces for building a slope: Iteration 1 Iteration 2 Connector peg with plate 1x2 with pinhole on bottom or any other hinge designs yield the same results. Maybe it could work but since I don't have local access to Bricklink and the likes, I couldn't physically test this out and have only Mecabricks to work with.

  • Welcome to Bricks.SE! I'm not quite sure what is your actual issue here. Do you need help finding a way to build a structure with specific angle? Specific length/width/height? It would also be nice if you added isometric picture (I have initially thought of your assembly in a different way, but now I see how it is put together).

    Have you also considered dedicated piece for building escalator: bricklink.com/v2/catalog/catalogitem.page?P=69900

  • Have you considered the hinge elements? The 1x2 Top Plate (also available as a 2x2) and the 1x2 Hinge Base can usually be used to provide many angles up to 90 assuming you're happy to rest the bottom somewhere.

  • @Zhaph-BenDuguid I've used it but there were misalignment issues. Please see EDIT 2 for further elaboration.

Could this work in you case? Using snot brick to build it vertically.

Slope 45°

EDIT 1:

The only way I managed to get your angle and snap it correctly is like that. I used stud.io with collision turned on to be sure it could work. I hope this can help you. 39.5 39.5°

EDIT 2: I found another solution using bar and bar with clip. This one is much more modulable but maybe less stable. Let me know what you think. enter image description here

EDIT 3: Adapted to use technic beam.

beam setup with beam

  • I don't think this could work. Do note that my slope is not at a 45 degree angle, and I very much want to make sure the slope is at the precise angle I've tested with so that the stairs remain leveled.

  • Do you know the exact angle you're looking for?

    According to Mecabricks, a 39.5 degree incline.

  • Could you try the first iteration again, but with connector pegs and Technic beams?

    How do you want the orientation of the beams? Holes on top (meaning the steps will slide on the holes) or holes on the side?

Update: Now that I have stud.io installed, I've finally got an upright design for the slope's framework as follows: 39.5 degrees slope (white) with supporting frameworks (green) This design was based off of @Hugo 's suggestion, but modified to use Technic pegs and Technic bricks for better stability.
