OPERATION
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 first.
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.
Only use original JDN chain boxes.
Do not exceed the permitted filling capacity of the chain box.
When operating without a chain box, avoid hazards due to
idle chain (falling, catching, impacting), see Operation
without chain box, page 19.
Never apply bending loads to chains.
Do not join or repair chains.
Do not work with a chain that is drawn tight, bent or extended.
Check blocked chains for damage.
Straighten twisted chains (defective bottom block)
Do not work with a damaged, worn or rusty chain.
Permitted operating temperature for chain and hook: – 20°C
to + 150°C, permissible ambient temperature: – 20°C to +
70°C, permitted heat absorption of hoist body: max. 90°C.
Never allow persons to enter the area below the suspended
load.
Never attempt to remedy a fault while a load is suspended.
Only use suitable and approved sling gear; do not jam the
hook at the point of attachment.
Ensure that the operator is not put at risk within the operating
area by sling gear or the load.
Follow the relevant instructions for attaching loads.
Before attaching the load, accurately position it vertically
below the hoist. The chain must hang vertically before lifting.
Ensure that the hook safety catch is closed.
Repair damaged hook safety catches.
Before lifting loads, ensure that the maximum permitted load
is not exceeded! Sling gear must be included in the weight of
the load.
During lifting and lowering, prevent accidents by ensuring that
the load remains stable and does not tilt or fall.
Never force jammed loads.
Only lift one load at a time; never several loads
simultaneously.
Never lock the control elements of the control devices.
If the control elements become difficult to operate, 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 expertly repaired and the hook replaced.
Never anneal the hook.
Only operate JDN Air Hoists with original JDN controls.
Uncontrolled, external force factors (e.g. due to hydraulic
cylinders, falling loads) are not permitted.
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 compressed air supply.
If the braking distance is excessive, repair the hoist.
If a load is lifted using several air hoists, prevent overloading
due to incorrect weight distribution.
Select a safe operating location.
Ensure the system pressure is correct.
Never touch metallic hand controls that 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 modifications by unauthorised persons.
