PRODUCT INFORMATION
EMISSIONS
Noise emissions
The noise emission data can be found in the Technical data table,
page 65ff.
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 operating air pressure specified by us.
In the hall, the noise pressure level drops by approx. 3 dB (A) every
time the distance is doubled.
Oil emissions
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, page 63). This also results in a reduction of the noise
emission values.
OPERATING CONDITIONS
JDN Air Hoists are extremely robust and require little maintenance.
They are suitable for use in potentially explosive 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.
+ 70°C, assuming they are not heated above this level due to
external influences. The thermal endurance of chains and hooks is
+ 150°C.
CAUTION!
When touching metallic hand controls which are
colder than 0°C, freezing of the skin can occur 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 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 heating may occur.
The controls become noticeably less sensitive.
DANGER!
Warning against excessive system pressures
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
3
(corresponds to Class 7 in accordance with ISO 8573-1 2001)
In order to provide adequate compressed air quality, operation with
a filter regulator is recommended. An oiler is not required in the
service unit, as the motor is provided with internal permanent
lubrication.
Pressure dew point must be 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:
the use of an upstream air dryer
if a service unit with oiler is used, adding anti-icing agent to
the lubrication oil (depending on moisture content of
compressed air), or using pneumatic oil (Part No. 11900) with
anti-icing additive for relevant temperature conditions.
In the event that your JDN Air Hoist is operated in combination with
a trolley, please also read the trolley operation instructions and the
relevant accident prevention regulations for operation with trolleys.
