1.1 This part of EN 12629, taken together with EN 12629-1:2000+A1:2010, applies to stationary and mobile equipment for the benched manufacture of prestressed products. The manufacturing bed is a machine with which other associated machines work simultaneously. Moreover, these machines are generally used on beds installed in parallel. EN 12629-1:2000+A1:2010 specifies general requirements applicable to machines for the manufacture of constructional products from concrete and calcium silicate. This document specifies the additional requirements to and/or the deviations from EN 12629-1:2000+A1:2010 specific to the machines it covers. 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.
