Assemble
the
beam
like
DA (1 and 3)
•
However, the A-support [80] is
assembled between the support
carrier [70] and the beam in front; it
is secured above and below by two
locking pints [60] each.
•

Aligning the roof extension
Align the roof extensions in such a way that their distance agrees with the C-clamp distance to the
working platform. Hoisting on a slant is not permitted.
9.1.4
Stability calculation for the roof extension
The stability calculation includes determining the number of counterweights according to Table 1 and
Table 3 as well as identifying the bearing capacity for the roof construction at the place where the roof
extension is to be set up according to Table 1 and Table 3. The bearing capacity for the roof
construction is to be identified for each individual load scheme.
