Introduction
This document is a type C standard as stated in EN ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of the other standards, for machines that
have been designed and built according to the provisions of this type C standard.
1 Scope
This standard applies for gantry-type and cut-to-size saws, consecutively called machines, designed to saw raw
slabs/tranches form natural stone, as e. g. granite and other natural stone-like materials.
This standard deals with all significant hazards, hazardous situations and events relevant to gantry-type and cut-to-
size saws, when they are used as intended and under conditions of misuse which are reasonably foreseeable by
the manufacturer (see Clause 4). This standard specifies the appropriate technical measures to eliminate or reduce
risks arising from the significant hazards.
This European Standard does not deal with:
 machines intended for operation in a potentially explosive atmosphere;
 upstream and downstream conveying elements for transporting the work pieces.
This European Standard does not deal with significant hazards associated with noise.
This European Standard does not deal with the following:
a) operation in severe environmental conditions (e. g. extreme temperatures, corrosive environment);
b) supply by electrical networks with voltages, frequencies, tolerances etc. different from those of public suppliers;
c) hazards due to errors in the software;
d) cordless remote controls.
This European standard does not cover machine operation in environments where electromagnetic disturbances
are outside the range of those specified in EN 61000-6-2:2005.
This document is not applicable to machinery which are manufactured before the date of publication of this
document by CEN.

3 Terms and definitions – Symbols and abbreviated terms
For the purposes of this document, the terms and definitions given in EN ISO 12100-1:2003 apply. Additional
definitions specifically needed for this document are added below.
3.1 Gantry-type and cut-to-size saw
Gantry-type and cut-to-size saw are machines, mounted on a base , which are mainly used to cut slabs/tranches of
natural stone. The cut-off wheel (tool) is constantly cooled with water during the working process.
Using a turntable and a pivoting arrangement to tilt the cut-off wheel, any working position can be racked in.
With a moveable gantry-type and cut-to-size saw the infeed results from a horizontal support at the bridge. The
kneeling of the cut-off wheel is made possible by a support mounted on the cross slide.
The main drive of a gantry-type and cut-to-size saw results from an electric motor.
3.2 Types of gantry-type and cut-to-size saws
Gantry-type and cut-to-size saws which are classified in two types characterised below:
Type 1: Machine with a moveable bridge, flexible support with cut-off wheel and a stationary work piece.
Type 2: Machine with a moveable and pivoting bridge, flexible support with cut-off wheel and stationary work
piece.
