The noise emission data can be found in the
Technical
data
table, page 63.
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 motor oil lubrication,
small amounts of lubrication oil will be released into
the environment with the outlet air.
Oil emissions can be prevented by using a filter silencer
(see
Filter silencer
section, page 61). This also results
in a reduction of the noise emission values.
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 to + 70° C if
they are not heated above this level due to external
influences. The thermal endurance of chains
and hooks is + 150° C.
WA R N I N G !
When touching metallic hand controls which
are colder than 0° C, the skin could freeze
within a few seconds, and for temperatures
above 43° C, burns can occur. As a protective
measure, please wear suitable gloves.
For stationary outdoor operation, hoists must be pro-
tected against weathering and the maintenance inter-
vals 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/m3
(corresponds to Class 7 according to
ISO 8573 - 1:2001)
In order to provide adequate compressed air quality,
operation with a service unit is recommended. Usually,
an oiler is not required in the service unit, as the motor
is provided with internal permanent lubrication.
Pressure dew point at least 10° C below the lowest
expected ambient temperature
Do not operate JDN Air Hoists with
other gases.
With moist air and ambient temperatures at or below
0° C, there is a danger of icing in the motor.
Icing can be prevented by
using an upstream air dryer or using a service unit
with oiler,
adding anti-icing agent to the lubrication oil
(depending upon moisture content of compressed air)
using compressed air oil (Art. no. 11900) with anti-
icing agent for relevant temperatures.
In case your JDN Air Hoist is operated in combination
with a trolley, please read also the trolley operation
manual and the relevant accident-prevention regulations
for operation with trolleys.
