7.1

Fitting the telescopic dome shaft

The telescopic dome shaft allows the shaft to be
smoothly adjusted to the terrain surface between
an earth cover of 140 mm and 340 mm (Mini tele-
scopic dome shaft) or 140 mm and 440 mm (Maxi
telescopic dome shaft). To assemble, the profile
seal (material EPDM) of the shaft dome is rubbed
in with plenty of soft soap (do not use lubricants
with a mineral oil base because they will corrode
the seal). The telescopic dome shaft is then
greased, slid in and aligned to the terrain surface.
7.2

Telescopic dome shaft for pedestrian loading

Important: To prevent loads from being trans-
ferred to the shaft, the telescopic dome shaft is
filled in layers with round gravel
8/16) and evenly compressed. Avoid damaging the
shaft dome and telescope. Then fit the cover
and lock it with the childproof lock, tightening the
screw on the cover sufficiently such that it
cannot be opened by a child.
7.3

Telescopic dome shaft for vehicle loading

If the shaft is installed below a surface driven on
by vehicles, the telescopic dome shaft
anthracite) must be lined with concrete in the collar
area (load class B25 = 250 kg/m²). The con-
crete layer must be at least 300 mm wide and ap-
prox. 200 mm high all the way round. To extend
the shaft, the cast iron telescopic dome shaft (max.
useful length 440 mm) and the extension sleeve
(max. useful length 300 mm) can be used.
Attention: Use the cast cover under all circumstances.
7.4

Telescopic dome shaft for HGV loading

When installing below surfaces driven on by
HGVs, the telescope is lined
7.3. The concrete rings
a cast frame with star-shaped load distribution
are then installed to support the cast cover. The
cast frame must have a contact area of approx. 1
m². To extend the shaft, the telescopic dome shaft
for HGV loading with class D cover, provided by
the customer (max. useful length 440 mm), and
the spacer (max. useful length 300 mm) can be
used.
Please note: Can only be driven over with HGV, if a self-supporting, steel -reinforced concrete bridge is
installed.
