Change the model and drawing.
56 USD 1 . Replace the bottom direction on the 50x30 tube.
The 2nd Increase the distance between the directors (low directors to locate as low as possible)
3 . Change the cover of the corpus on the whole flexible leaves (there are sketches)
and 4. Change the design of the block of rolls (change the material from the laser, to the corner)
and 5. Making a shorter val
6 . Change the size of the upper roll
7 . Changes to reduce the loss of the field
8th Change the size in some details (it is a sketch)
The 9. Create a montage scheme in 2 types of fixation
The output should be a 3D model, and 2D drawing

If this is a modernization of the project where the lack of strength has already been found, then I propose to make a calculation of the strength:
1 . Determine the load.
The 2nd We calculate the tension in the elements.
3 . Identify the rigidity of the structure. (it is in the case when the strength is sufficient, but the structure has movements that interfere with the work of the mechanisms)
3 . We verify the strength of the static and the strength of the dynamic - during movement. in different positions. During the start and stop. Because at these moments the mass can multiply by 1.5-2*g.
You may think that is overwhelming. But if you don’t do this, your next project may be – “replace already the 50x50 tube.”

Змінити обшивку корпуса на цільні гнуті листи (є ескізи)
Це студентський проєкт? Чи планується робити цей сходовий ліфт для інвалідного візка в реальності?

Для інвалідного візка

А розрахунки на міцність зробили по зміні конструкції і ви їх надаєте?
Бо робить зміну конструкії без розрахунків це наражати на небезпеку користувачів цього ліфта.
-
якщо це модернізація проекту де вже виявлена недостатня міцність, то пропоную виконати розрахунок на міцність:
1. Визначаємо навантаження.
2. Розраховуємо напруження в елементах.
3. Визначаємо жорсткість конструкції. (це у випадку коли міцність достатня, але конструкція має переміщення, які заважають роботі механізмів)
3. Перевіряємо міцність статичну і міцність у динаміці – під час руху. У різних положеннях. Під час старту і зупинки. Бо в ці моменти маса може множитись на 1,5-2*g.
Можливо вам здається це зайвим. Але якщо цього не зробити, наступний ваш проект може бути – «замінити вже на трубу 50х50».
