Original instruction manual for
pewag standard lifting chains

General Description

pewag standard lifting chains are manufactured from pewag chains, connecting links and accessory parts.
The main function of the lifting chain is to serve as a connection between a load to be lifted and a crane hook
(fastening) that in turn, leads to the lifting and transportation of the load. The maximum working load limit as well
E
as in most cases the associated angle of inclination for multi-leg chains, number of chain strands and the nominal
diameter of the chain can be found on the tag.
pewag standard lifting chains should only be operated by properly trained persons. The longevity of the chains
and a high level of safety can only be safeguarded if used correctly and as instructed which in turn should prevent
accidents to persons or property. Therefore reading and understanding this instruction manual is of utmost
importance before using lifting chains, but one should not neglect the importance of carrying out activities in a safe
and responsible manner. The instruction manual should be easily accessible to all until such time as the machine is
decommissioned. The manual undergoes constant updating, hence only the most recent version should be seen as
valid which can be downloaded from www.pewag.com

Intended Use

Intended application: fastening and lifting and/or transporting loads.
Detailed information on the intended use can be found in the corresponding sections on the following pages.
Working load limit: the maximum load capacity (weight) of the lifting chain depends on the chain dimensions (d),
the number of chain strands, the angle of inclination (β), the sling configuration – see load capacity table.
The maximum load capacity can also be taken from the marking (stamping) on the tag, but only when it's intended
use is implemented correctly.
Application Temperature: Detailed information on the application temperature can be found in the corresponding
sections on the following pages.
Angle of Inclination: The angle of inclination is the angle between the chain lane and an imaginary vertical line.
If multi-leg chains are used, the angle of inclination must lie within the specified range of 0-45° and/or 45-60° and
should not differ from each other by more than 15°. Angles of inclination under 15° should be avoided.
The weight of the load to be lifted should be divided equally amongst each chain strand. This is the case when the
chain strands are ordered symmetrically to one another; which means that:
with a three-strand lifting chain, the lifting
points should be the same distance apart
or rather that they depict an equilateral
triangle with each angle at 120°
(see figure 1).
with a four-strand lifting chain, the lifting
points should depict a rectangle or square
with pairs of angles identical (see figure 2).
