DIN EN 1004 Explained: The Mobile Tower Standard and What It Means
"DIN EN 1004" is printed on almost every professional mobile scaffold tower – but what does it mean? Why is the standard so important, and what does it specifically mean for buyers, operators, and users? This article explains the standard in an understandable way, without simply reciting the legal text.
What is DIN EN 1004?
DIN EN 1004 is the European standard for mobile access and working towers made of prefabricated elements – precisely what is known as a mobile scaffold tower in the trades. The standard defines the requirements a mobile scaffold tower must meet in terms of load-bearing capacity, stability, assembly, labeling, and documentation.
The standard applies to mobile scaffold towers with working heights up to 12 meters indoors and up to 8 meters outdoors (these limits may vary depending on the manufacturer). For greater heights, supplementary manufacturer information applies.
Why is the standard so important?
Anyone who buys a mobile scaffold tower that is not certified according to DIN EN 1004 is buying a product without a standardized safety guarantee. This has practical consequences:
- In the event of damage, the operator is liable if the scaffold cannot demonstrate CE marking and DIN EN 1004 conformity.
- Employers' liability insurance associations may object to the use of non-standard-compliant scaffolds.
- Cheap imports without standard certification may seem attractive at first glance – in the event of an accident, precisely this will be scrutinized.
Scaffold classes according to DIN EN 1004
The standard distinguishes between different scaffold classes depending on the permissible live load on the platform:
| Class | Permissible load | Typical use |
|---|---|---|
| 1 | 75 kg/m² | Light inspection work |
| 2 | 150 kg/m² | Private users, occasional use |
| 3 | 225 kg/m² | Commercial use, trades |
| 4 | 300 kg/m² | Heavy material, construction |
| 5 | 450 kg/m² | Industrial use |
| 6 | 600 kg/m² | Heavy industrial applications |
In the trades, Class 3 (225 kg/m²) is the most common requirement for commercial mobile scaffold towers. Euroscaffold scaffolds achieve Class 3 to 4, depending on the model.
What the standard specifically requires
- Load-bearing capacity: The platform must bear the specified load evenly distributed without deforming or failing.
- Stability: The scaffold must be secured against tipping. Above a certain height, stabilizers or outriggers are mandatory.
- Guardrails: A side guardrail is mandatory from a fall height of 2 m. The Euroscaffold Professional with advanced guardrail fulfills this requirement with particular safety.
- Access: Access to the platform must be safe – usually via internal ladders within the frame.
- Castors: The castors must be braked and designed for the total weight. Suitable scaffold wheels are available separately.
- Marking: Every standard-compliant scaffold bears a CE marking, the scaffold class, the year of manufacture, and the maximum working height.
- Assembly instructions: The standard prescribes complete assembly instructions. Anyone who deviates from these leaves the certified system composite.
What to check when buying
- Is CE marking present?
- Are assembly instructions included in the scope of delivery?
- Is the scaffold class specified? For commercial use, at least Class 3.
- Are stabilizer specifications available? From what height are outriggers mandatory?
- Manufacturer's proof? Reputable manufacturers provide complete technical documentation.

DIN EN 1004 and employer obligations
As an employer, you are obliged by the German Industrial Safety Ordinance (Betriebssicherheitsverordnung - BetrSichV) to use only tested and safe work equipment. Mobile scaffold towers are work equipment within the meaning of the BetrSichV. This means that only standard-compliant scaffolds may be used, assembly must comply with the manufacturer's instructions, and their condition must be regularly checked.
Conclusion
DIN EN 1004 is not a bureaucratic hurdle, but the technical basis for a mobile scaffold tower to deliver on its promises. Standard-compliant scaffolds from brand manufacturers protect users and operators equally – legally and physically. At Gerüstexpress, all mobile scaffold towers are certified according to DIN EN 1004 and are supplied with complete documentation. Contact us with questions about system selection.
FAQ: DIN EN 1004
Which scaffold class do I need as a tradesperson?
For common trade use (painters, drywallers, electricians), Class 3 (225 kg/m²) is the standard. For heavy material or several people on the platform simultaneously, Class 4 is recommended.
How do I recognize a standard-compliant mobile scaffold tower?
By the CE mark, the specified scaffold class, and the enclosed assembly instructions with the manufacturer's name and technical data.
Does DIN EN 1004 also apply to private use?
The standard is mandatory in the commercial sector. For private DIY enthusiasts, it is not legally required, but it is a sign of tested quality and therefore always recommended.
