Core drilling machines on stand - Safety

This European Standard applies to core drilling machines on transportable stands equipped with a diamond
core drill bit, usually with a water supply connection device, and intended to drill holes into stone, concrete and
similar mineral materials in a stationary position where the power for the tool rotation is supplied by an
electrical, hydraulic, pneumatic or internal combustion prime motor.
The feed movement of the drill head and core drill bit may be effected by manual, mechanical or hydraulic
means.
This European Standard deals with all significant hazards pertinent to core drilling machines on a stand when
used as intended and under the conditions foreseen by the manufacturer (see clause 4). This standard
specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards.
This standard does not apply to:
- percussive or rotary-percussive rock drills either mounted or unmounted;
- hand held power drills;
- hydraulic or pneumatic power supply sources;
- mobile undercarriages to which machines can be fitted.
This European Standard does not apply to machinery covered by EN 791:1995.
This European Standard covers electrical hazards by making reference to relevant European Standards (see
5.2).
Those hazards that are relevant for all mechanical, electrical, hydraulic and other equipment of machinery and
that are dealt with in standards for common use are not covered by this European Standard. Reference to
pertinent standards of this kind is made where such standards are applicable and so far as is necessary.
In this European Standard, core drilling machines on a stand are called "machines" and diamond core drill bits
are called “tools”.
NOTE The term "diamond" is used as a generic word which covers all varieties of abrasive products such as
diamond, borum nitride.
This European Standard applies primarily to machines which are manufactured after the date of approval of
the standard by CEN.

Kernbohrmaschinen auf Ständer - Sicherheit

Dieses Dokument ist für Kernbohrmaschinen auf transportablen Ständern anwendbar, die mit einer Kernbohr
krone mit Diamant oder Bornitrid mit oder an oder Wasserzulaufanschluss ausgestattet und dafür vorgesehen sind, Löcher in Stein, Beton und ähnliche mineralische Werkstoffe in einer stationären Position zu bohren, wobei die Energiezufuhr für die Werkzeugrotation durch einen elektrischen, hydraulischen, pneumatischen oder einen Antriebsverbrennungsmotor erfolgt. Die Bohrmaschineneinheit kann mit einem weichen
gerät ausgestattet sein.
Die Vorschubbewegung des Bohrkopfs und des Kernbohrers kann durch manuelle, elektrische, hydraulische oder pneumatische Mittel erfolgen.
Dieses Dokument behandelt alle wesentlichen Gefährdungen, Gefährdungssituationen oder Gefährdungs- ereignisse mit Bezug zu Kernbohrmaschinen auf einem Ständer, wenn sie bestimmungsgemäß und unter Bedingungen von durch den Hersteller vernünftigerweise vorhersehbaren Fehlanwendungen verwendet werden (siehe AnhangA).
Dieses Dokument legt die entsprechenden technischen Maßnahmen fest, um die aus den signifikanten Gefähr
dungen in Verbindung mit der Lebensdauer der Maschine resultierenden Risiken, die in ENISO12100:2010, 5.4, beschrieben werden, zu beseitigen oder zu verringern.
Dieses Dokument ist nicht anwendbar für:
—
Bohrhämmer oder Stein-Schlagbohrmaschinen, montiert oder unmontiert;
—
Handbohrmaschinen;
—
hydraulische oder pneumatische Energieversorgungsquellen;
—
mobile Fahrgestelle, auf denen Maschinen montiert werden können;
—
Maschinen Geräte für Bohr- und Gründungsarbeiten (die in EN16228-1:2014 bis -7:2014) behandelt wer
den;
—
Maschinen mit Elektroantriebsmotor ≤3,7kW, die in EN62841-3-6:2014 behandelt werden.
In diesem Dokument werden Kernbohrmaschinen auf einem Ständer als „Maschinen“ und Diamantkernbohrer als „Werkzeuge“ bezeichnet.
ANMERKUNG Der Begriff „Diamant“ wird als allgemeiner Begriff verwendet, der alle Arten von Schleifwerkzeugen wie Diamant, Bornitrid oder ähnliches umfasst.
Dieses Dokument ist nicht für Kernbohrmaschinen auf Ständer anwendbar, die vor dem Veröffentlichungsda
tum dieses Dokuments hergestellt wurden.
