DA N G E R !
For all air hoist applications, ensure that
the load hook can be lowered all the way
to the ground, in order to prevent a load
being moved to the lower limit position,
without reaching the ground. Danger due
to overloading.
DA N G E R !
Never use hoists on the ground if they are
not specifically intended for horizontal
pulling.
DA N G E R !
The fatigue strength of chains is significantly
impaired due to extreme corrosion (pitting
corrosion). There is a
danger of fracture
.
Hydrogen-induced embrittlement with resul-
tant stress cracks due to highly corrosive
media (e.g. seawater) may affect high-
strength steels (e.g. chains). Danger of frac-
ture! This process is promoted by so-called
recombination poisons. Examples of these are
hydrogen sulphide, cyanide, arsenic com-
pounds and rhodanide.
If rusty chains are not replaced for opera-
tional reasons, crack inspections are to be
carried out at intervals of three months.
Company operating instructions
In the case of particularly difficult lifting equipment
applications, the company must provide comprehensible
operating instructions in the language of the operator,
within the framework of this operation manual. Here,
measures for safe operation are stipulated in accordance
with prevailing operating conditions.
Furthermore, it is essential that all the regulations set
out in sections
Intended use
, page 15 and
Operating
conditions,
page 16 are observed.
