Introduction
This European Standard is a Type C standard as stated in EN 1070.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this European Standard.
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.
This European Standard specifies the additional requirements to and/or the deviations from EN 12629-1 specific for
the Stationary and mobile equipment for long line manufacture of pre-stressed products as defined in clause 3.
With the aim of clarifying the intentions of the standard it should be noticed that the following assumptions where
made when producing it:
specific conditions of use or environmental conditions out of the scope of the standard shall be the subject of
negotiations between the manufacturer and the user/owner;
the equipment will only be used by competent and designated persons;
the place of use/installation is adequately lit;
All operations are carried out by specially trained operators.
1 Scope
1.1 This European Standard is intended to be used together with EN 12629-1 “Machines for the manufacture of
constructional products from concrete and calcium-silicate — Safety — Part 1: Common requirements", which
specifies general requirements of machines for the manufacture of constructional products from concrete and
calcium-silicate.
The manufacturing bed is a machine with which other associated machines work simultaneously. Moreover, these
machines are generally used on beds installed in parallel.
1.2 This standard gives particular requirements for the design of the following machines:
Pre-stressing bed (schematic representation is given in annex A);
Bed sweeper, vacuum cleaner, oiler, wire-guide machine (schematic representation is given in annex B);
Bed layout machine (schematic representation is given in annex C);
Strand pushing/pulling machine (schematic representation is given in annex D);
Spinner, extruder, vibrodistributor (schematic representation is given in annex E);
Tarpaulin paying out and winding in machine (schematic representation is given in annex F);
Sawing machine (schematic representation is given in annex G).
NOTE The manufacturing operations include some or all of the following:
treating pre-stressing bed with release agent;
"marking out" the elements (slabs, plain slabs, etc.) to be made;
running the pre-stressing strands;
pre-tensioning;
installing the shutterings, (formwork, side shutters, end plates and inserts)
fixing reinforcement;
tensioning;
concrete distribution and compaction;
winding out the tarpaulin;
heating;
detensioning;
removal of shettering, formwork, etc. ;
strands cutting or sawing;
removal of final products;
bed cleaning.
The concrete supply interface which is taken into account for safety is also considered.
The sequence of these operations can be different according to the manufacturing process used in the factory and
to the various types of products.
1.3 This European Standard deals with the significant hazards pertinent to these machines, when they are used
as intended under the conditions foreseen by the manufacturer (see clause 4), except noise hazards which are
partly dealt with and hazards due to handling the package of cut wires and placing them on beds.
NOTE Amendment is under preparation to deal with noise, in particular for measures to reduce noise at source and a noise
test code including noise declaration.
This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the
significant hazards.
1.4 Sub-clause 1.3 of EN 12629-1:2000 applies.
1.5 Sub-clause 1.4 of EN 12629-1:2000 applies.
NOTE At the designing stage, in complement to this standard, other type C standards dealing with similar hazards can be
used for some of the machines and equipment mentioned in this standard. EN 13862 for Floor sawing machines or EN 1454 on
portable saws can be a help to design the saws described in this standard.
1.6 This document is applicable to equipment for long-line manufacture of pre-stressed product which are
manufactured after the date of publication of this document by CEN.
