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.
