INTroDUCTIoN
Products of CMCO Industrial Products GmbH
have been built in accordance with the state-
of-the-art and generally accepted engineering
standards. Nonetheless, incorrect handling
when using the products may cause dangers
to life and limb of the user or third parties
and/or damage to the hoist or other property.
The operating company is responsible for
the proper and professional instruction of
the operating personnel. For this purpose, all
operators must read these operating instruc-
tions carefully prior to the initial operation.
These operating instructions are intended to
acquaint the user with the product and enable
him to use it to the full extent of its intended
capabilities. The operating instructions contain
important information on how to operate the
product in a safe, correct and economic way.
Acting in accordance with these instructions
helps to avoid dangers, reduce repair costs
and downtimes and to increase the reliability
and lifetime of the product. The operating
instructions must always be available at the
place where the product is operated. Apart
from the operating instructions and the
accident prevention act valid for the respec-
tive country and area where the product is
used, the commonly accepted regulations
for safe and professional work must also be
adhered to.
The personnel responsible for operation,
maintenance or repair of the product must
read, understand and follow these operating
instructions.
The indicated protective measures will only
provide the necessary safety, if the product
is operated correctly and installed and/or
maintained according to the instructions. The
operating company is committed to ensure
safe and trouble-free operation of the product.
TEMPErATUrE LIMITS IN EXPLoSIVE
ATMoSPHErES AND DUSTS
In order to determine the maximum surface
temperature, several tests have been per-
formed with nominal load under extreme con-
ditions. The maximum surface temperature
has been determined at a room temperature
of 20 °C to 22 °C without dust deposit and
without safety factors!
Based on these tests, the Yalelift range has
been classified in temperature class T4
(135 °C maximum surface temperature) for
gases. The relevant values for dusts can be
found in table 6.
En
These values refers to a lowering process of up
to 10 m without disruption. For longer lowering
processes, e.g. 15 m or more, breaks must be
made for cooling.
The hoist may be used at ambient tempera-
tures between –20 C° and +40 °C. Consult
the manufacturer in the case of extreme
working conditions.
The temperature range refers to –20 °C up
to +40 °C. In case of deviating loading or
temperature ranges consult the manufacturer.
Units for operation in areas with poten-
tially explosive gases/air resp. steam/
air atmospheres or inflammable mist
The temperatures of all equipment, protective
systems and components surfaces which can
come into contact with explosive atmospheres
must not exceed the ignition temperature of
the combustible gas or liquid during normal
operation and in the case of malfunctions.
However, where it cannot be excluded that
the gas or vapour can be heated to the
temperature of the surface, this surface tem-
perature must not exceed 80 % of the ignition
temperature of the gas measured in °C. This
value may only be exceeded in the case of
rare malfunctions.
Units for operation in dust /air
atmospheres
In areas, which are explosive by inflammable
dusts, the surface temperature must not
exceed ⅔ of the minimum ignition point in
degrees Celsius (°C) of the dust/air mixture.
Temperatures of surfaces, which can be
subject to dangerous deposits of ignitable
dusts, must be one safety margin lower than
the minimum ignition temperature of the
layer which can possibly be generated by the
respective dust. This requires a safety margin
of 75 K between the minimum ignition point
of a dust deposit (ignition temperature) and
the surface temperature of the unit. If the dust
deposit exceeds a thickness of 5 mm, larger
safety margins are required.
The relevant key data of dusts can be called
up via the GESTIS-STAUB-EX database at
www.dguv.de or taken from the HVBG/BIA
report 12/97 "Combustion and explosion
characteristics of dusts" and be converted:
Starch / milk powder / gelatine
Ignition temperature 390 °C x ⅔ = 260 °C
max. permissible surface temperature.
Wood / grinding dust
Ignition temperature 290 °C - 75 °C = 215 °C
max. permissible surface temperature.
Classification of the hoists
After intensive testing under extreme condi-
tions the hoist series Yalelift can be classified
for correct operation in the general industry
as follows in Tab. 6.
The documents have been checked by a
nominated body (0035) and deposited at
TÜV Rheinland Industrie Service GmbH,
Haumannplatz 4, 45130 Essen.

SPArK ForMATIoN

Materials subject to danger of friction
and impact
Individual sparks can be generated as a result
of frictional and/or impact processes and, as
a consequence, can be the cause dangers of
ignition in gases or impact-sensitive dusts.
Increased danger of ignition may emanate
from clashing of special material pairings.
These are non corrosion-resistant steel or
cast iron against magnesium or pertinent
alloys. This applies especially in case of rust
(e.g. surface rust).
Especially at the friction points of the chain
and load hook rust (surface rust) may occur.
For correct operation of the product it must
therefore be ensured that there is no rust at
these wear points and that in the application
area there are no material combinations of the
above-mentioned aluminium alloys and steel
(exception: antirust steel) at possible friction,
impact or grinding points; thus spark formation
by these material combinations as a result of
mechanical impact can be excluded.
Hand and load chain
Always ensure that the hand chain, load
chain and the load are guided to exclude
grinding and/or sliding contact with external
constructions or components. Depending
on the degree of corrosion, the conductive
discharge capability of hand chains and/or
load chains can worsen to an effect that it is
not adequate any longer. For operation this
means that rusty hand chains and/or load
chains must no longer be used.
ATTEnTion: The user has to operate the unit
to avoid sparking from the hand chain as well
as from the load chain.
