As an operator of hoists, you are responsible for
your own safety and for that of your colleagues in
the working area of the hoist.
Hoists may only be operated by persons charged with
this task by their company.
Before using the JDN Air Hoist for the first time,
familiarise yourself with all permissible operating
conditions. For this purpose, read through this opera-
tion manual thoroughly and perform the described
actions on the hoist, step by step.
Report each malfunction to your safety officer imme-
diately, so that the fault can be remedied without
delay.
Adhere to the regulations of the accident prevention
authorities (e.g. Berufsgenossenschaft regulations in
Germany).
Observe the section
"Intended use"
on page 14.
The following are classified as non-intended use:
Oblique pulling of loads in general.
Definition of oblique pulling
Oblique pulling is the deviation of the load chain and
the chain hoist from the vertical position, for a force
acting in a straight-line between the point of force
application of the load on the load hook and the
point of suspension on the supporting structure.
Under special safety provisions, depending upon the
particular situation, JDN Air Hoists may be used for
oblique pulling. In this case, a chain box must not be
used, as the chain may fall out or become knotted.
Oblique pulling is not permitted for devices installed
in trolleys. Please contact us, if required.
Detaching or dragging of loads.
Loading of the hook at the tip.
Catching of falling loads.
Carrying persons (see
Intended use,

Jog control over long lift paths
Switching to the opposite direction with load in
