JDN Air Hoists are designed for lifting and lowering
loads within the specified load-carrying capacities, with
a vertically-arranged chain. They are also suitable for
pulling loads horizontally. In combination with trolleys,
JDN Air Hoists are also suitable for the floorless hori-
zontal movement of loads.
Any other use or use outside these stipulations is
deemed to be impermissible. J.D. NEUHAUS GMBH & CO.
KG cannot be held liable for any resultant damage. The
entire risk is borne by the user (see also
Rules for safe
operation of hoists,
page 23).
The noise emission data can be found in the
Technical
data
table, pages 43.
The noise pressure level of the measurement area at a
distance of 1 m from the machine surface was measured
in accordance with DIN 45 635, Part 20, at the operat-
ing air pressure specified by us. In the hall, the noise
pressure level drops by approx. 3 dB (A) every time the
distance is doubled.
If the device is operated with additional motor oil lubri-
cation, small amounts of lubrication oil will be released
into the environment with the outlet air.
JDN Air Hoists are extremely robust and require little
maintenance. They are suitable for use in explosion-
hazardous areas, as well as in areas with increased
concentrations of soot and dust, high humidity and
at ambient temperatures of - 20° C up to approx. + 50° C
if they are not heated above this level due to external
influences. The thermal endurance of chains and hooks
is + 150° C.
C AU T I O N !
When touching metallic hand controls which
are colder than 0° C, the skin could freeze
within a few seconds, and at temperatures
above 43° C, burns may occur. As a protec-
tive measure, please wear suitable gloves.
For stationary outdoor operation, hoists must be
protected against weathering and the
maintenance intervals must be shortened.
Depending upon the version, JDN Air Hoists must be
operated at a system pressure of 4 bar or 6 bar (see
information on the nameplate). If the system pressure
is too low, important functions of the hoist will be
impaired:
The brake will drag and is thus subject to a
high degree of wear. An impermissibly high degree
of warming could take place.
The controls become noticeably less sensitive.
DA N G E R !
Warning against excessive system pres-
sures
Operating with excessive system pressures
results in danger due to overloading.
Therefore, the pressure must be limited to
that specified on the nameplate.
JDN Air Hoists must be operated with a sufficiently
clean and dry air supply. The air supply must fulfil the
following quality requirements:
Particle size less than 40 µm
Particle density less than 10 mg/m
