Excellent project, very good analysis, just a consultation:

- Do you have a reference gearbox in the current market?

Re: -- Aquilesmorillo (talk) 23:18, 15 December 2020 (CET)

Thank you, the most important thing is to select a gearbox with a high ratio like the one used here of 1:100 and with the required safety to prevent the load from being returned. Here is a reference, that supplier offers reducers with auto-blocking system (99 series) and with the required ratio:

Part number 1.18 -- Inddigital (talk) 23:43, 15 December 2020 (CET)

Will a 10 mm cable be sufficient to carry a 200 kg load?

Re: Part number 1.18 -- Aquilesmorillo (talk) 23:54, 15 December 2020 (CET)

Sure, you can use this table as a guide:

D [inch]	D [mm]	Safe Load [kN]
1/4	6.4	4.89
5/16	8	7.56
3/8	9.5	10.9
716	11.5	14.7
1/2	13	19.0
9/16	14.5	24.0
5/8	16	29.7
3/4	19	42.3
7/8	22	57.4
1	26	74.3

For 3/8" [9.5 mm], we have a safe load of 10.9 kN [1111 kg]

How is the mechanical behavior in extreme cases, such as impacts?

Re: -- Aquilesmorillo (talk) 03:05, 16 December 2020 (CET)

A simulation was made as an example, which shows the mechanical behavior to a vertical impact load caused by a slope, obtaining satisfactory results, you can see it at:

You used a program to compare the height of this frame with the height of a person, where can I get that program, is it Open Source?

Re: Part number 1 -- Aquilesmorillo (talk) 03:38, 16 December 2020 (CET)

That program is fSpy, (Open source still image camera matching), is Open Source, it was used as part of the reverse engineering process. You can find it at:
