23、418:2000+A1:2009 (E) 4 Introduction This European standard is a Type C-standard as stated in !EN ISO 12100-1:2003“. The machinery concerned and the extent to which hazards are covered is indicated in the scope of this standard. 1 Scope This European Standard applies to transportable masonry and ston
24、e cutting-off machines stationary during work, principally used on job site building construction for cutting-off stones, other mineral construction materials and composite materials having at least one supporting surface. The power for the tool rotation is supplied by electrical or internal combust
25、ion prime motor. This European Standard deals with all significant hazards pertinent to masonry and stone cutting-off machines for job site (see clause 4), when they are used as intended and under the conditions foreseen by the manufacturer. This European Standard specifies the appropriate technical
26、 measures to eliminate or reduce risks arising from the significant hazards. These machines are designed for use with rotating diamond cutting-off wheels with a continuous rim and/or segmented rim. This European Standard does not apply to: metal cutting-off machines; wood and timber sawing machines;
27、 machines with a feed or descent mechanism other than manual, or with a pedal; mobile machines on a trolley travelling on the ground; hand-held portable grinding and cutting-off machines; hand-held portable grinding and cutting-off machines mounted on a support to be used in a fixed position. This E
28、uropean Standard does not cover the operation of transportable masonry and stone cutting-off machines in potential explosive atmospheres. This European Standard covers electrical hazards making reference to relevant European Standards (see 5.2). Those hazards that are relevant for all mechanical, el
29、ectrical, hydraulic, pneumatic 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 necessary. In this standard, the masonry
30、 and stone cutting-off machines for job site construction are called: “cutting-off machines“ or “machines“, and cutting-off wheels are also called: “tools“. This standard applies primarily to the machines which are manufactured after the date of approval of the standard by CEN. BS EN 12418:2000+A1:2

42、. 3.1 cutting-off machine transportable machine used in building and site construction, operating at a stationary position and is intended for cutting primarily construction material of different weight, shape and dimensions, for example natural stone, concrete (reinforced or otherwise), bricks, con
43、crete blocks (breeze blocks), paving slabs or cobblestones, roof tiles and ceramic tiles. The feed of the material or of the table where it is placed is made by hand. The cutting head, if movable, is moved manually or by a pedal. The power source of a cutting-off machine is an electrical motor or an
44、 internal combustion engine with built-in tank. 3.2 types of cutting-off machines cutting-off machines can be basically classified in four different types defined below: Type 1: Machine with a movable table having a fixed (permanently or by means of clamps) or swinging moveable cutting head (tiltabl
45、e or not) which is located over the table; Type 2: Machine with a fixed table having a horizontal moving cutting head and, if applicable, vertically adjustable and tiltable cutting head located over the table; Type 3: Machine with a fixed table having a vertically moving cutting head; Type 4: Machin
