JDN Air Hoists must not be used for the following
applications, for example:
Critical areas of nuclear plants.
Over acid baths or other plants with
corrosive substances.
In areas in which organic acids are present.
To ensure the safety of personnel and property
when using JDN Air Hoists, it is essential that the
following points are observed:
Lift the load carefully at the beginning.
Never touch a running chain.
Never use the hoist chain for attaching loads.
Never allow loads to fall into the hoist chain.
If the chain is slack, do not take up the load
at maximum speed.
When operating without a chain box, avoid hazards
due to idle chain (falling, catching, impacting),
see section
Operation without chain box, page 17.
Never apply bending loads to chains.
Do not join or repair hoist chains.
Do not operate with a chain which is drawn tight,
bent or extended.
Check blocked chains for damage.
Straighten twisted chains (defective bottom block)
Do not operate with damaged or worn or rusty chains.
Permissible operating temperature for chain and
hook:
- 20° C to + 150° C, permissible ambient temperature:
- 20° C to +50° C, permissible heat absorption of the
hoist body: max. 90° C.
Never allow persons to enter the area below the
suspended load.
Never attempt to remedy a fault with a load
suspended from the hoist.
Only use suitable and approved attaching aids;
do not jam the hook at the point of attachment.
Please ensure that the operator is not put at risk with-
in the operating area by attaching aids or the load.
Follow the relevant instructions for attaching loads.
Before attaching, accurately position the load verti-
cally below the hoist. The chain must hang vertically
before lifting.
Ensure that the hook safety catch is closed.
Before lifting loads, ensure that the maximum
permissible load is not exceeded. Attaching aids
must be included in the weight of the load.
When taking up and setting down, ensure stable
positioning of the load, to prevent accidents due
to tilting or falling loads.
Never drive against jammed loads.
Only use original JDN chain boxes .
Only lift one load at a time; never several loads
simultaneously.
Never lock the control elements of control devices.
In the case of stiff actuating elements , have the
hoist repaired.
In the case of power failure, secure the load and
the surrounding area, until the power is restored.
Never use or repair bent, open or deformed load
hooks. The hoist must be repaired and the hook
must be replaced.
Never anneal the hook.
Only operate JDN Air Hoists with original
JDN controls .
Uncontrolled, external force factors (such as due
to hydro cylinders, falling loads) are not permitted.
Repair damaged hook safety catches.
Repair stiff hook bearings.
Do not kink or pinch control hoses.
Have loosened bolted connections tightened by
the Repairs department.
Before removing compressed air hoses, shut off
the main air supply.
Do not exceed the permissible capacity of the
chain box.
Repair the hoist if the braking distance is excessive.
If a load is lifted using several air hoists, prevent
overloading due to incorrect weight distribution.
Select a safe operating location.
Ensure the correct system pressure.
Never touch metallic hand controls which are colder
than 0° C or hotter than 43° C, without suitable
protective gloves.
Do not make modifications to the hoist.
Only use original JDN spare parts.
J.D. Neuhaus GmbH & Co. KG accepts no liability for
the use of non-original components and/or modifica-
tions by unauthorised persons.
Do not switch on multi-chain hoists if the bottom
block is supported.
Special safety precautions must be taken when lifting
loads into areas which are out of sight.
