Curved stair lift

Rail geometry solved per staircase, with the model and drawings generated from the result.

Sectional schematic of a curved stair lift running up a staircase: a double curved rail on wall-fixed mounting brackets, a swivel seat and footrest at the bottom, and a motor housing at the top, with travel and radius dimensions marked.Inspect image

The design task

No two staircases are the same, so the rail has to be solved for each one.

The geometry is the hard part: rail radius, travel and mounting points all depend on each other and on the stair itself.

What the automation handles

  • Rail geometry solved from the staircase measurements
  • Model generated from the solved geometry
  • Section and assembly drawings produced from the model

Generated output still needs the checks and approvals required by your engineering and manufacturing process.
