scope:

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. 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. 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. This document deals with automatic and semi-automatic operations of modules A and C and with automatic operations of module B. There are two main types of stationary and mobile equipment for manufacture of precast reinforced products: - equipment with instant removing from mould on pallet boards or on the floor; - equipment with delayed removing from mould (collection of moulds: the concrete products are hardened in the mould). This standard does not deal with the machines for: - mixing of concrete; - manufacturing of the reinforcing steel; - evacuation of the products to the stockyard; . manufacturing of products (e. g. slabs or blocks) covered by other parts of EN 12629. Annex A shows the most common types of units as well as their variations: immediate demoulding unit and delayed demoulding unit. This document is limited to the units comprising a fixed or movable manufacturing module with or without rolling over of the mould, a module or storage area for storing/hardening of the products and a products palletising/packaging module. It deals with the significant hazards pertinent to these machines, when used as intended under the conditions foreseen by the manufacturer (see Clause 4), except noise hazards, which are partly dealt with. This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards, particularly: - following a malfunction during the automatic mode of operation; - during manual or semi-automatic manufacturing processes; - during end-of-shift cleaning procedures, adjustment and maintenance. This document deals with the significant hazards generated by handling equipment for palletising and stacking/destacking that are gantries. Complementary safety measures can be necessary if other type of handling equipment is used. This document is not applicable to stationary and mobile equipment for the manufacture of precast products, which are manufactured before the date of publication of this document by CEN.
