DEHA 6325
Assembly Instructions
Polski
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.
DEHA Lifting loops 6325
The DEHA 6325 Lifting loops are
used to transport precast reinforced
concrete elements. The loop is made
of high strength steel cable shaped to
an oval and secured 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 coeffi
cents
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 distan-
ces must be observed during installa-
tion:
• embed depth t
• loop projection ü
• minimal spacing e

• minimal element thickness

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

Q-Mesh reinforcement
bent to a U-shaped
The required minimum and additional
reinforcement must be installed acc.
to static specifi cations. The concrete
cover of the 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 DEHA Lifting loops are installed
in the small side of a minimal thick-
ness 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 orien-
tation is not allowed
.
