2.á Overhead
Clearances
When choosing the stairway ensure
there is adequate overhead clearance for boarding the platform
at the upper and lower landings.á The ASME
A18.1 requirement is 80ö.
Similarly, ensure there is
overhead travel along the entire travel path of the platform.á The ASME requirement
is 60ö above any point on the platform deck.
If platform arms fold up, they may
pose overhead problems when the platform is
being called in the folded position.
