Your skiphoist is travelling at a very
slow speed.
The tolerances for the rail are not very critical.
Use the tolerances that are used for overhead
cranes for example.
I would use as follows:
Rail centres +/- 3 mm
Rail level between supports along the rail
length devided by 1000
Rail level between the two rails
span devided by 1000
These tolerances are adequate for the speed
you use.
Kind regards,

Could someone please advise on acceptable tolerances for the rails of an inclined skip hoist with an angle of 12 degrees to vertical. Vertical lift is 38 metres and speed is 0.35m/sec. The payload is 3000 kg. ■
