The basis for the following information is an expert
statement by the DMT Gas & Fire Division on the use of
JDN Hoists, Trolleys and Crane Systems in potentially
explosive areas and is based on European Directive
94/9/EC
1
(“ATE X 100a”). DMT is accredited with the
testing of devices and protection systems for intended
use in explosion-hazardous areas.
BASIC EXPLOSION PROTECTION
FOR THE STANDARD VERSIONS
Standard version JDN air hoists are category 2 devices
(Guideline 94/9/EC, DIN EN 1127-1
2
), for use in zone
1 and 2 for gases of explosion group IIA. (Also see IEC
60079-12
3
and IEC 60079-20
4
). These devices are also
suitable for use in zone 2, in the presence of gases of
explosion group IIB, provided that the substances
hydrogen sulphide and ethylene oxide can be excluded
and additionally in zones 21 and 22 for dusts with glow
temperatures above 210° C or ignition temperatures
above 202° C, provided that no light metal or other
impact-sensitive dusts are present.
These devices are designated by:
II 2 GD IIA T4(X)/II 3 GD IIB T4(X) Additional
designation “ X ” see page 10.
JDN HOISTS
“WITH INCREASED SPARK PROTECTION”
JDN hoists of the version “with increased spark protec-
tion” (FS) satisfy additional explosion protection
requirements. With the exception of carbon disulphide
(temperature class T6), they can be used in the pre-
sence of all gases in zones 1 and 2 and dusts with glow
temperatures above 210° or ignition temperatures above
202° in zones 21 and 22, and can be marked
II 2 GD IIC T4(X) for installation in a trolley,
depending upon the trolley version (see below), but
also with
II 2 GD IIB T4(X) . For further operating
conditions, see Instructions for safe operation (Notes
and
).
JDN HOISTS FOR USE IN THE PRESENCE OF TEMPERATURE
CLASS T6 GASES OR EXTREMELY EXPLOSIVE DUSTS
Following separate tests, especially with regard to
ambient temperatures and type of operation, use in the
presence of carbon disulphide or dusts with particularly
low glow or ignition temperatures may be possible with
designation
II 2 GD IIC T6(X) , which includes the
additional designation “ X ” for special conditions (see
Additional designation “ X ”). Please contact us with
regard to these requirements.
STANDARD JDN TROLLEY AND CRANE RUNNING GEAR
JDN trolleys and cranes can be used in zone 2 with
standard running wheels (made of steel or cast metal)
with all dusts and the presence of gases up to explosion
group IIC. Due to the low running speeds, the possible
friction velocities on the running wheels are less than
1 m/s, which means that standard running wheels can
also be used in zone 1 up to explosion group IIB. The
highest possible designation for these devices is:
II 2 GD IIB T4(X)/II 3 GD IIC T4(X) . Depending
on the hoist version, it may have the designations
II 2 GD IIA T4(X)/II 3 GD IIB T4(X) or
II 2 GD IIB T4(X) .
JDN TROLLEY AND CRANE RUNNING GEAR
“WITH INCREASED SPARK PROTECTION”
For use in zone 1 in the presence of gases in explo-
sion group IIC, bronzed running wheels or running
wheels made of bronze are also used. The highest
possible designation for this version (FSR) is
II 2 GD IIC T4(X) (the same as for JDN hoists
“with increased spark protection”).
JDN TROLLEY AND CRANE RUNNING GEAR FOR USE IN THE
PRESENCE OF TEMPERATURE CLASS T6 GASES OR DUSTS
As is the case with JDN hoists “with increased spark
protection”, temperature class T6 is also possible here
in the case of a special investigation of applicability,
permitting the highest possible designation for standard
wheels
II 2 GD IIB T6(X)/II 3 GD IIC T6(X)
