Conveying, spraying and placing machines for concrete and mortar - Safety requirements

1.1   This European Standard specifies the safety requirements for
-   conveying machines,
-   spraying machines,
-   placing machines, and
-   delivery line systems
for concrete and mortar as defined in the definitions in 3.3 to 3.6.
The machinery can be stationary or mobile.
This European Standard does not cover:
-   machines that are mobile during conveying, spraying and placing;
-   cabins for any machines covered by this standard;
-   additional functions beyond conveying, spraying and placing concrete and mortar, e.g. separate mixing function or crane function;
-   requirements for operation in tunnels;
-   support structures (i.e. tower systems) not exclusively designed for the use with concrete distribution booms.
This European Standard does not establish the additional requirements for operations subject to special rules (e.g. potentially explosive atmospheres, supply by electrical networks where voltage, frequency and tolerance differ from those of the public supply, earthquake, lightning, using on public roads, etc.).
1.2   This European Standard deals with all significant hazards, hazardous situations and events relevant to conveying, spraying and placing machines when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards during transportation, assembly, dismantling, disabling, scrapping, operation and maintenance.
1.3   This European Standard is not applicable to machines which are manufactured before the date of publication of this document by CEN.

Stroji za transport, brizganje in polaganje betona in malte - Varnostne zahteve

Ta evropski standard določa varnostne zahteve za – stroje za transport, – stroje za brizganje, – stroje za polaganje in – sisteme tekočega traku za beton in malto, kot je opredeljeno v definicijah od 3.3. do 3.6. Stroji so lahko nepremični ali premični. Ta evropski standard ne pokriva: – strojev, ki so premični med transportom, brizganjem in polaganjem; – kabin katerega koli stroja, obravnavanega v tem standardu; – dodatnih funkcij, ki presegajo področje transporta, brizganja ter polaganja betona in malte, npr. ločene mešalne funkcije ali funkcije dvigala; – zahtev za obratovanje v predorih; – podpornih struktur (tj. stolpnih sistemov), ki niso namenjeni posebej uporabi z betonskimi distribucijskimi drogovi. Ta evropski standard ne vzpostavlja dodatnih zahtev za postopke, za katere veljajo posebna pravila (npr. potencialno eksplozivna okolja, napajanje prek električnih omrežij, kjer se napetost, frekvenca in toleranca razlikujejo od tistih za javno omrežje, potrese, razsvetljavo, uporabo javnih cest). Ta evropski standard obravnava vsa pomembna tveganja, nevarne situacije in dogodke, ki se nanašajo na stroje za transport, brizganje in polaganje, ko se uporabljajo v skladu z njihovim namenom in pod pogoji pričakovane nepravilne uporabe, ki jih določa proizvajalec (gl. točko 4). Ta evropski standard določa ustrezne tehnične ukrepe za odpravo ali zmanjšanje tveganj, ki izvirajo iz pomembnih nevarnosti med transportom, sestavljanjem, razstavljanjem, onemogočanjem, razrezovanjem, obratovanjem in vzdrževanjem. Ta evropski standard ne velja za stroje, ki so bili proizvedeni pred datumom, ko je Evropski odbor za standardizacijo objavil ta dokument.

Overview

EN 12001:2012 - Conveying, spraying and placing machines for concrete and mortar - Safety requirements is a European type-C standard issued by CEN that defines safety requirements for machines used to convey, spray and place concrete and mortar. It applies to stationary and mobile machinery and delivery-line systems but excludes machines that are mobile during operation, cabins, additional functions (e.g. integrated mixers or cranes), tunnel operation and certain support structures. The standard addresses hazards throughout the machine lifecycle: transport, assembly, operation, maintenance, dismantling and scrapping. It also supports the essential requirements of EU Directive 2006/42/EC.

Key topics

EN 12001:2012 covers a broad set of technical and safety topics, including:

• Hazard identification and risk reduction for conveying, spraying and placing machines and delivery line systems
• Mechanical and control-system safety, including requirements aligned with EN ISO 13849-1 for control reliability
• Hydraulic and pneumatic failure prevention and related protective measures
• Electrical safety and EMC (electromagnetic compatibility) considerations (references include EN 60204-1 and EN 13309)
• Stop systems, thermal protection and exhaust-fume management
• Ergonomics, operator controls and multiple control-station requirements
• Fixed guards, stability and transport/travel safety provisions
• Noise emission testing and declaration (Annex C: noise test code)
• Verification, inspection and marking requirements, including verification tables and inspection records
• Documentation and traceability: Instruction Handbooks, Log Book (Annex B) and marking for pumps, booms, hoses and delivery systems
• Remote control function allocation (normative Annex D)
• Diagrams and machine classification examples (informative Annex A)

Applications

This standard is essential for:

• Manufacturers and designers of concrete pumps, shotcreting machines, mortar-conveying and spraying machines, placing booms and delivery-line systems
• Safety engineers and compliance officers performing risk assessments and CE conformity tasks
• Test laboratories and notified bodies performing verification, noise testing and inspection
• Construction site managers and maintenance teams implementing safe use, inspection schedules and logbooks

Practical uses include designing machine guards and control systems, preparing instruction manuals, compiling log books and inspection reports, performing noise measurements, and ensuring machines meet European safety and marking requirements.

Related standards

EN 12001:2012 references and complements other machinery and safety standards such as:

• EN ISO 13849-1 (control-system safety)
• EN 60204-1 (electrical equipment of machines)
• EN 13309 (EMC for construction machinery)
• Ergonomics and guard standards (EN 614-1, EN 894 series, EN 953)
