Moving STB units on a trolley
STB units can be moved quickly
with the STB trolley if a crane
cannot be used, e.g. in tunnels.
The trolley can be installed on
the STB 450 (Fig. 41.3) and the
STB 300/300 plus (Figures 41.1
and 41.2).
Installing the trolley waler
The trolley waler is bolted to the
support frames (counter plates
and nuts are already attached
to the waler). When moving the
unit, a counterweight is required
to prevent tilting (the weight
depends on the formwork height
and support frame used). Each
unit requires two trolley walers,
four wheel adapters and four
trolley spindles 48/70. Depending
on the weight, four swivel-type
castors for 2, 6 or 10 tons
are required. The wheels are
mounted to the waler by raising
the unit with the spindle.
Attention
Æ
The support frames must
not stand on the trolley spindles
while pouring. When using the
STB 300, remove the trolley
waler adjacent to the panels,
otherwise anchoring is not pos-
sible. Observe the trolley waler
instructions.
Æ
When moving or tempo-
rarily setting down the support
frame, its stability must be veri-
fied by means of a calculation.
