CRABESCAL

STAIRWAYS

Overall stability and triangulation

Crab public stairways must be supported and braced so as to withstand the working loads to which they are exposed

as well as the force of the wind. Downward loadings on the standards will be checked on each installation in order to

take into account the effect of the height and working loads on the legs.

Supports

The ground strength will be checked and load distribution systems, where necessary, will be firmly secured. The

materials used for supports will be checked. In the case of stairway towers built on a slab, this will need full attention,

more particulary with regards to its under shoring structure.

Anchor points

These will be firmly secured or anchored to the main structure or to any other point of adequate strength.

The materials used in the supports will also be checked.

Service stairways: where these are included in façade scaffolding, additional anchoring at each level is compulsory.

Please see the technical instructions for the location of anchor points.

Public stairways: testing

Crab public stairways have been tested under static and dynamic loads, as well as under loads varying at different fre-

quencies (additional clauses in the standards directives), tests carried out at the C.E.B.T.P. and registered under

N° 2343.6.838 as regards compliance with current French standards.

Please contact our engineers if you require any additional information.
