(Main)Core drilling machines on stand - Safety
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
Diese Europäische Norm gilt für Kernbohrmaschinen auf transportablem Ständer, die mit einer Diamantkernbohrkrone
und im Allgemeinen mit einer Vorrichtung für die Wasserzufuhr ausgestattet und für das Bohren
von Löchern in Stein, Beton und ähnliche mineralische Materialien in stationärer Position vorgesehen sind.
Die Antriebsenergie für die Drehbewegung des Werkzeugs kann durch elektrischen, hydraulischen, pneumatischen
oder Verbrennungsmotor zur Verfügung gestellt werden.
Die Vorschubbewegung des Bohrkopfes und der Bohrkrone kann manuell, mechanisch oder hydraulisch
erfolgen.
Diese Europäische Norm behandelt alle signifikanten Gefährdungen, die auf Kernbohrmaschinen auf Ständer
zutreffen, wenn sie bestimmungsgemäß und entsprechend den Empfehlungen des Herstellers verwendet
werden (siehe Abschnitt 4). Diese Norm spezifiziert die entsprechenden technischen Maßnahmen zur Beseitigung
oder Verminderung der Risiken, die von den signifikanten Gefährdungen ausgehen.
Diese Norm gilt nicht für:
- Schlag- oder Drehschlagbohrmaschinen für Stein mit oder ohne Bohrgestell;
- handgeführte motorgetriebene Bohrmaschinen;
- hydraulische oder pneumatische Energiequellen;
- Fahrgestelle, auf die Kernbohrmaschinen aufgebaut werden können.
Diese Europäische Norm gilt nicht für Maschinen, die in EN 791:1995 behandelt werden.
Diese Europäische Norm behandelt elektrischen Gefährdungen durch Verweis auf relevante Europäische
Normen (siehe 5.2).
Die Gefährdungen, die für alle mechanischen, elektrischen, hydraulischen und anderen Einrichtungen von
Maschinen relevant sind und in entsprechenden allgemeinen Normen behandelt werden, umfasst diese
Europäische Norm nicht. Soweit erforderlich, wird auf anwendbare Normen dieser Art verwiesen.
In dieser Europäischen Norm werden Kernbohrmaschinen auf Ständer als „Maschinen“ und Diamantkernbohrkronen
als „Werkzeug“ bezeichnet.

5 Safety requirements and/or measures Machinery shall comply with the safety requirements and/or measures of this clause and in addition with !EN ISO 12100-1:2003 and EN ISO 12100-2:2003" for hazards which are relevant but not significant and which are not dealt with in this standard. For the application of EN 294:1992, !EN 953", EN 982:1996, EN 983:1996 and !EN 60204-1:2006" the manufacturer shall carry out an adequate risk assessment for the requirements thereof where choice is necessary. NOTE This specific risk assessment should be part of the general risk assessment relating to the hazards not covered by this standard. Covering each individual significant hazard is sufficient for covering combinations of hazards. 5.1 Mechanical hazards 5.1.1 General As components and parts have to be manually handled, all the accessible parts shall be free of sharp parts and burrs which could generate hazards when setting, using, handling, and maintaining the machine. Burrs resulting from, for example, manufacturing, casting or welding shall be eliminated and sharp edges shall be smoothed. 5.1.2 Protection against moving parts 5.1.2.1 Transmission parts Rotating transmission parts (for example shafts, couplings and belt drives) with the exception of the drive spindle end shall be provided with fixed guards to prevent contact. !These guards shall comply with EN 953 and 5.3.2.2 of EN ISO 12100-2:2003." Fixed guards shall be held in position either by welding or by mounting them in such a way that they can be opened or removed only with the aid of tools or keys. Guards shall comply with the provisions of EN 294:1992 on safety distances.
Safety distance for hand fed machines The shortest distance between a manual feed control device and the tool(s) intended by the machine manufacturer shall be > 2,5 cm. 5.1.4 Stability !deleted text" 5.1.4.1 !Stability during work" The drill stand shall be equipped with fixing devices which will allow rigid and safe mounting to the material to be drilled. For anchor fixing, slotted hole(s) shall be provided. Nuts and screws intended to adjust the stand in position shall need intentional action to loosen them. NOTE Due to the various existing fixing systems for different machine applications it is not possible to give precise technical requirements for these systems in this standard. 5.1.4.2 !Stability during transportation, assembly and dismantling As the stability of the drill rig is not given for these situations the operators manual shall give instructions for safe handling." SIST EN 12348:2000+A1:2009
All machines with remote control and/or automatic feed shall be fitted with an easily accessible emergency stop in the system. This emergency stop shall be in accordance with EN ISO 13850:2008. It shall stop all dangerous movements as quickly as possible without creating an additional hazard." 5.1.6 Failure of the power supply An interruption of the power supply and a reestablishment after an interruption shall not lead to a dangerous situation in particular: the machine shall not be restarted automatically, an intentional action shall be necessary; the machine shall not be prevented from stopping if the stop command has been given; neither movement nor dangerous actions shall occur.
Such failures shall not impede any stop function. NOTE Manual feed machines, the power of which does not exceed 750 W and which are intended to be used with core drills, the diameter of which does not exceed 60 mm are considered as presenting no particular danger in the case of restoration of energy supply. 5.1.7 Dissipation of residual energy On pneumatically powered machines a main line valve shall be provided which either connects the machines to the air supply or in the closed position shuts off the air supply and releases the air pressure in the drilling unit when stopping the machine. SIST EN 12348:2000+A1:2009
These shields shall be designed to reduce the heat transfer from the surface to the body of the operator. This may be achieved by a structured surface, ribs or special coating. 5.4.4 Test method The test method to verify the surface temperature of the machine is prescribed in annex C. The machine parts whose temperatures exceed the permissible limits of !EN ISO 13732-1:2008" for a contact time not exceeding 1 s and whose surface is greater than 10 cm², shall not be accessible to the test cone (see annex C).
