Bracket SL-1
This is used if there are no suitable points of appli-
cation for the lowering cylinder beneath the Heavy-
duty supporting unit (either because the clearance
between the System beam and the ground is too
small, or because there are no cross-profiles)
Travelling gear distancer SL-1 330mm
Where large HD supporting units are used under
straight cover-slabs, the entire slab load momentar-
ily rests on the lowering cylinders when the load is
taken off the lowering wedges.
These momentary loads are no problem for the
Lowering cylinders SL-1 250kN, as these cylinders
are equipped with an overload function.
Lowering procedure
1) If the traveller units are not already pre-mounted,
position them centrally beneath the HD support-
ing units
(depending on the repositioning method that has
been selected).
2) Using the Lowering cylinders (D) , slightly raise
the unit (thereby taking the load off the lowering
wedge).
3) Take the load off the heavy-duty supporting unit
(A) with the aid of the lowering wedges (E) and a
suitable ring or fork spanner (width-across
46mm).
4) Remove the lowering wedges.
5) Using the Lowering cylinders, lower the entire
unit onto the traveller units or (if these are
already mounted) down to the ground.

If it cannot be guaranteed that the load will
remain under 200 kN, then the Travelling
gear distancer SL-1 must be used
