Operating conditions
CAUTION
Operational safety risk
Safe operation is only possible under the specified conditions. Contact the manufacturer if the operating condi‐
tions differ from those specified
"After-sales service", Page 10
The chain hoist and the trolley can be operated at:
Ambient temperature:
-20 °C to +45 ℃,
Humidity:
max. 80 % relative humidity,
Height:
up to 1000 m above sea level,
Type of enclosure:
IP55,
Electromagnetic compatibility:
Resistance to interference in industrial environments,
Interference emission for residential, commercial and light-industrial environ‐
ments.
Tab. 19
Demag chain hoists operating outdoors should be provided with a cover for protection against the weather or
chain hoists, trolleys and travel drives should be kept under shelter if they are not in use.
Special operating conditions may be agreed with the manufacturer in individual cases.
Such operating conditions may occur in the following applications, for example:
● Galvanising or electroplating facilities,
● Hygiene areas,
● Low or high temperature applications.
On request, suitably optimised equipment and important information for safe, low-wear operation can be supplied
for these applications.
Stronger cut-off springs need to be used under certain circumstances:
● DC1-10 with 1/1 reeving hook assembly – use of cut-off springs (optional)
- for very high mechanical demands on the buffers, e.g. frequenct contact with sharp edges,
- for extreme ambient conditions (high-temperature applications, foundries, etc.).
● DK10 bottom block with external cut-off springs (optional)
- for extreme ambient conditions (high-temperature applications, foundries, etc.).
Reduced duty factor at increased ambient temperatures
If DC chain hoists are operated at ambient temperatures that differ from
Tab. 19, Page 27, the duty factor must
be reduced:
Ambient temperature
-20 °C to +45 °C
>+45 ℃ to +50 ℃
>+50 °C to +55 °C
>+55 ℃ to +60 ℃
