Basket hitch
Basket hitch rigging method:
In the single-wrapped rigging method, also called bas-
ket hitch, the attachment device is wrapped once in
a U-shape around the load. The loose ends are guided
upwards and hooked into crane hook or load lifting
device; so the load only rests in the lifting slings. To
double the working load limit, the angle of inclination
ß must not exceed 6°.
It is not permitted to use for attachment in basket hitch!
Except for the attachment of:
• large loads, provided the attachment devices are
prevented from slipping together and the load is
prevented from shifting.
• long rod-shaped loads, provided that an inclination
of the load, a slipping of the attachment devices and
ejection of the load or parts of the load are avoided.
This requirement does not apply to the lifting and raising
of the load close to the ground.
Double looped attachment method
This method offers greater safety for loose bundles
by additional looping of the load. The determination
of the working load limit of suspension gears requires
particular attention for the looped and double looped
attachment methods. For example, the working load
limit of a single-leg suspension gear remains unchan-
ged when the hook is hooked into the suspension ring
after looping. If, in the case of a single-leg ring chain,
the ring is hooked into the crane hook after the looping,
the working load limit of a two-leg suspension gear is
assumed (see Fig. 4.7.2 to 4.7.5).

4.8 Fixtures

For the intended use of the fixtures, it is essential to take
into consideration their specific operating manuals,
unless they are described in greater detail in this
instruction manual.

5. Limits of use

CAUTION: Do not move chain slings over
sharp edges (edge radius less than nominal
thickness of the chain). Use edge protectors
or intermediate layers to protect chain. In
case of use on unprotected sharp edges, the
working load limit of the chain in DE, CH and
LU must be reduced by 20 % according to
DGUV rule 109-017. According to ÖNORM,
the WLL must be reduced by 50 %. Coun-
try-specific regulations must be observed.
For example, this type of load occurs with choker hitches.
