Static Electricity; Correct Operation - Columbus McKinnon YLITP ATEX 500 Instrucciones De Servicio

Hand chain 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.
YLITP/YLITG and YLLHP/YLLHG models must always be operated from below. For additional
safety and to avoid sparking by impact or friction during operation, the units are equipped with
stainless steel hand chains. The MEDIUM and HIGH models in addition have copper-coated
load and top hooks. The HIGH model is also equipped with a stainless steel load chain.
Trolleys are always provided with buffers. The MEDIUM and HIGH lines in addition are fitted
with solid bronze wheels.
Attachment points
Attachment points have to be selected to ensure that the expected forces can be safely
absorbed. The unit must align freely under load in order to avoid impermissible additional
loading.
S E
TATIC LECTRICITY
In order to avoid electrostatic charging on plastic parts, do not use parts of the attachment
(e.g. round slings) in the area of facing panels, hand chain guide and cap.
Cleaning only with a damp cloth (when cleaning these components, make sure to apply
only materials which do not allow electrostatic charging).
Special feature of hydrogen (explosion group IIC): Hydrogen only requires an extremely small
energy for ignition. For this reason, we recommend that prior to application of the unit a
release measurement be carried out. The spark for ignition may be generated electrostatically
or mechanically by handling of a tool, for example.
C O
ORRECT PERATION
The Yalelift ATEX range is exclusively intended for lifting, lowering and pulling of loads up to
the indicated load capacity. The units may be used in potentially explosive areas (see
identification). In combination with trolleys (YLITP/YLITG and YLLHP/YLLHG), the hoists are
also suitable for overhead horizontal moving of loads, with model YLLHP/YLLHG featuring an
extremely low headroom.
ATTENTION: Trolleys must be provided with buffers.
ATTENTION: The unit may be used only in situations in which the load carrying
capacity of the device and/or the supporting structure does not change with the load
position.
Any different or exceeding use is considered incorrect. Columbus McKinnon Industrial
Products GmbH will not accept any liability for damage resulting from such use. The risk is
borne by the user or operating company alone.
The load capacity indicated on the unit is the maximum working load limit (WLL) that may be
attached.
If the hoist is to be used for frequent lowering from large heights or in indexed operation, first
consult the manufacturer for advice because of possible overheating.
