BEGU telescopic dome shaft
On installation under areas used by trucks with a
maximum weight of 12 t, the telescope
is supported as
described in point 6.2. The concrete rings
(Ø 600 mm)
and a cast frame
with star-shaped load distribution for
mounting the cast cover are then installed (observe earth
coverage of at least 800 mm, max. 1200 mm). The cast
frame must have a supporting area of approx. 1 m².

Assembling the adapter
For lager coverage heights a adapter is needed. To insert
the adapter into the tank dome, soft soap is needed. Into
the highest groove of the adapter the profile seal is
inserted an greased generously. Afterwards push the
telescopic dome shaft into the adapter and adapt it to the
planned area surface.
1 Adapter = max. earth-cover 1.350 mm
2 Adapter = max. earth-cover 1.500 mm
(in each case in connection with the Maxi telescopic
dome shaft)
The entire system must be checked for leaks, cleanliness and stability at least every three months.
The entire system should be serviced at intervals of approx. 5 years. In this case, all parts of the
system must be cleaned and their function checked. Servicing should be carried out as follows:
-
Drain the tank completely
-
Clean surfaces and internal parts with water
-
Remove all dirt from the tank
-
Check that all internal parts are firmly seated.
