scope:

This European Standard is intended to be used together with EN 12629-1:2000 "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. 1.1 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). 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. 1.2 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. This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards. 1.3 Sub-clause 1.3 of EN 12629-1:2000 applies. 1.4 Sub-clause 1.4 of EN 12629-1:2000 applies. 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.
