1.1 This document 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.
This document specifies the additional requirements to and/or the deviations from EN 12629-1 specific for the stationary and mobile equipment for the manufacture of precast reinforced products as defined in Clause 3.
This document applies to these machines also when used for the manufacture of non-reinforced moulded products.
1.2 This document applies to the modules comprising production machines (with or without turnover demoulding) for the manufacturing of reinforced moulded products as shown below and illustrated in informative Annexes A and B.
NOTE This machinery can consist of three modules and they are generally designed to obtain a large moulding capacity (middle length of the products from 3 to 4 meters), with a limit height of demoulding of 1 m and a maximum width of 1,50 m.
Module A: Manufacturing machines by vibration or compression and floating, with or without turnover.
Module B: Stocking/hardening unit.
Module C: Assembly for palletising/packaging of the concrete products. This module also permits the inspection of the products.
These machines are designed to perform the following cyclic operations:
— manufacturing by vibration and even compression (oiling, mould feeding – concrete + reinforcement –, vibration, floating, interlocking, turnover, removing from mould);
— storage of moulds and pallet boards for concrete hardening;
— products destacking and packaging;
— moulds and pallet boards return to the manufacturing module.
Any of these operations may be manual, semi-automatic or automatic.
