RULES FOR THE SAFE
OPERATION OF HOISTS
As a hoist operator, you are responsible for your own safety
and 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 these operation instructions thoroughly and
carry out the described actions on the hoist, step by step.
Immediately report any malfunctions to your safety officer, so
that the fault can be remedied without delay.
Adhere to the regulations of the accident prevention
authorities (e.g. Berufsgenossenschaft (trade association)
regulations in Germany).
Always comply with the information listed under Intended
use on page 16.
The following are regarded as improper use:
Changing load-carrying capacity depending on load position:
JDN Air Hoists are not equipped with load-carrying capacity
indicators, they may therefore only be used in those
applications in which the load-carrying capacity does not
change with the position of the load.
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.
Oblique pulling
Under special safety provisions relevant to the particular
situation, JDN Air Hoists may be used for oblique pulling (see
Intended use, page 16).
In this case, a chain box must not be used, as the chain may
fall out or become knotted. Oblique pulling is not permitted if
hoists are installed in trolleys or running gear. Please contact
us, if required.
Breaking free or dragging of loads.
Loading of the hook at the tip.
Catching falling loads.
Carrying persons (see Intended use, page 16).
Jog control with a load on the hook.
Switching to the opposite direction with a load in motion.
Approaching lifting and lowering limiters during normal
operation.
Never hold the chain in the area of the centre section under
tension at the upper or lower limit position of the load hook.
