Crane ganging
For crane ganging, each panel
must be attached to the sup-
port frame STB 300/300 plus or
STB 450.
STB 300/300 plus units
STB 300/300 plus units with a
width up to 3.50 m are moved
by attaching the crane hook
to the formwork (Figures 40.1
and 40.2). Always use two crane
hooks with sufficient capacity!
STB 450 units
The STB 450 and the height
extension 150 are equipped with
crane eyes. When transport-
ing STB 450 units with height
extensions above the ground,
attach the 4-rope crane sling
to the crane eyes of the top
height extension (Figures 40.3
and 40.4). Every crane eye has a
capacity of 3.2 tons (this applies
to both the STB 450 and the
height extension 150).
Attention
Æ
Do not break the STB units
free from the concrete using the
crane!
Æ
When setting STB units on
the ground, always ensure they
do not tip over, using ballast if
necessary. Even when setting the
unit down temporarily, ensure
that it is secured to prevent it
tipping over, for example due to
wind gusts. This can be achieved
using additional supports on the
facing side or setting down the
units so that they rest against
each other.
