- from 7 to 10° - ladders;
- from 11 to 25° - ladders with railings;
- from 26 to 30° - gangways with steps and railings;
- from 31 to 45° - stairs with horizontal steps and handrails;
- more than 45° - stair compartments.
Depending on the angle of inclination of the mining, the ladder can be produced in various configurations.
The design makes it easy to assemble several separate ladders into a single highway.
