Horisont Stairway
Assembly
NOTE!
If the steps lean backwards due to the supporting surface not being level,
the stairway must be collapsed slightly. This is achieved using the handrail.
The lock must be released at the same time. Now place blocks on the sup-
porting surface under the rear side rails to make the stairway’s contact
point level. This is a difficult procedure and the stairway should be partially
opened during erection. Complete opening is performed as in point 4.
5. If the stairway is to be anchored at the upper end, use a slab attachment or
scaffold hook.
Erecting a stairway against a sloping surface
When a stairway is erected on sloping earth or rock, it should be anchored
at both top and bottom. If the stairway is to be in place for a long period, it
should be fitted with additional manual locks to prevent the semi-automatic
locks working loose in use.
Mounting slab attachments
Two slab attachments shall be used to anchor the stairway.
Mount the slab attachments in the holes at the upper end of both jointing
irons. The slab attachments can be placed on the inside or outside of either
side rail. Anchor the stairway by bolting the slab attachments to the support-
ing surface or similar.
--- NOTE! ---
The slab attachments are to be mounted with the curve turned upwards
