HALFEN DEHA 6325
The corresponding operating information including the installation and assembly instructions must
be readily available in the precast plant and on site. The instructions must be observed.
HALFEN DEHA Lifting loops 6325
Fig. 1
The HALFEN DEHA 6325 Lifting
loops are used to transport precast
reinforced concrete elements. The
loop is made of high strength oval
shaped steel
cable and fi xed with a pressed
ferrule.
The lifting loops are identifi ed with a
colour label marked with the name of
the manufacturer, the year of produc-
tion and the load class (see Fig. 1).
The load capacity must be verifi ed
according to the specifi c require-
ments. All infl uencing factors must
be considered in the calculation,
for example;
• impact factor
• diagonal pull
• adhesion factor
Installation (Fig. 2 and 3):
The lifting loops are always installed
in the top accessable surface of the
precast element. Longitudinal or
lateral orientation is possible. The
loop-end with the ferrule is positioned
in the formwork.
The following dimensions and
distances must be observed during
installation:
• embedment depth t
• loop projection ü
• minimal spacing e /2
Z
• minimal element thickness

The identifi cation label on the lifting
loop must remain visible after pouring

the concrete.
The required minimum and additional
reinforcement must be installed acc.
to static specifi cations. The concrete
cover of the HALFEN DEHA Lifting
loop and the additional reinforcement
must be in accordance with EC2.
Crane hooks can be connected
directly to the protruding lifting loops:
• The bending radius of the hook
used for lifting must be equal or
greater than the diameter of the
cable.

• Sharp-edged hooks must be
avoided.
• The allowable maximum spread
angle is 60°, e.g. diagonal pull is
permitted up to 30°.
If the HALFEN DEHA Lifting loops are
installed in the small side of a minimal
thickness element, they can be
orientated either parallel (fi g. 2) or
perpendicular (fi g. 3); in this case
diagonal pull at right angles to the
walls main orientation is not allowed.
