The Machinery Directive 2006/42/EC of the European Parliament and Council, dated May 17, 2006, serves as a pivotal legal framework governing machine safety within the European Union. Its primary aim is to ensure a high level of health and safety protection for machine users. However, beyond traditional machinery, the directive also encompasses a variety of other products essential for maintaining a safe working environment. This article delves into these products regulated by the directive, even if they are not conventionally recognized as machines.

Scope of the Machinery Directive 2006/42/EC
The Machinery Directive outlines safety and health requirements not only for machines but also for other products that directly impact their operation and user safety. It includes a range of components and devices that, while not machines in the traditional sense, are crucial for the safe and efficient functioning of machinery.
What Else Does the Machinery Directive 2006/42/EC Regulate?
- Safety Components
- Definition: Safety components are elements designed to fulfill safety functions, marketed independently, whose failure or malfunction endangers personal safety. These critical components must operate reliably to ensure the safety of machines and their users.
- Examples: Emergency stop devices, protective guards, hazard detection and monitoring systems, enclosures.
- Emergency stop devices: These allow for the rapid shutdown of machinery in case of danger, minimizing accident risks.
- Protective guards: They shield operators from hazardous machine parts, such as moving components.
- Hazard detection and monitoring systems: These include sensors and monitoring systems that detect potential hazards and can automatically stop the machine if necessary.
- Enclosures: Physical barriers that separate operators from dangerous machine zones, providing an additional layer of protection.
- Chains, Ropes, and Belts
- Characteristics: Chains, ropes, and belts are designed and manufactured for lifting as part of lifting machinery or lifting accessories. These elements must be extremely durable and wear-resistant to ensure safety during the lifting and transport of heavy loads.
- Significance: Essential for the safe and effective operation of lifting machinery, such as cranes and hoists. Their failure can have catastrophic consequences, thus they must meet stringent quality and safety standards.
- Incomplete Machines
- Definition: Incomplete machines are assemblies that are almost machines but cannot serve a specific application independently. A drive system is an example of an incomplete machine. These products require further assembly or integration with other components before they can be used.
- Requirements: They must comply with specific procedures before being placed on the market, including technical documentation and assembly instructions. The manufacturer must provide detailed information to enable the safe completion and use of the machine.
- Detachable Mechanical Power Transmission Devices
- Description: Detachable mechanical power transmission devices are components that transmit power between self-propelled machines or tractors and other machines by connecting them at the first fixed bearing. These components allow for flexible and efficient power transmission in various mechanical systems.
- Examples: Universal joints, drive belts.
- Universal joints: They enable power transmission between components that may be slightly misaligned or rotate at different angles.
- Drive belts: These transmit power between pulleys, allowing for power transmission over long distances and in various configurations.
- Interchangeable Equipment
- Definition: Interchangeable equipment are devices mounted on a machine or tractor by the operator to change its function or assign a new function. These elements enable quick and easy adaptation of machines for different tasks.
- Examples: Excavator buckets, various tool attachments mounted on drills.
- Excavator buckets: Allow for various types of earthworks, from digging to material loading.
- Tool attachments on drills: Enable a wide range of applications, from drilling to milling and threading.
- Lifting Accessories
- Definition: Lifting accessories are elements or equipment not attached to the lifting machine that enable the load to be held, placed between the machine and the load or on the load itself. These components ensure safe and efficient lifting and transport of loads.
- Examples: Slings, hooks, lifting clamps.
- Slings: Flexible straps or ropes used for lifting and transporting loads, easily adaptable to various shapes and sizes of loads.
- Hooks and clamps: Elements that allow for the secure attachment of loads to lifting machines, ensuring stability during lifting.
Products Excluded from the Directive’s Scope
The directive also excludes certain products from its scope, including:
- Weapons, including firearms.
- Means of air, water, and rail transport, excluding machines mounted on these means of transport.
- Special equipment intended for use in amusement parks or fairgrounds.
- Machines designed specifically for military and police applications, often subject to other specific regulations.
The Importance of Compliance with the Machinery Directive 2006/42/EC
Compliance with the Machinery Directive is crucial for manufacturers as it ensures access to the EU market and guarantees that products are safe for users. The directive sets stringent requirements for design, production, and conformity assessment that must be met before a product is marketed. For end-users, this means reduced risk of accidents and a higher level of health and safety protection.
Manufacturers meeting the directive’s requirements can mark their products with the CE mark, indicating compliance with European standards. This builds consumer and business partner trust, facilitating growth in the European market.
Practical Application
In practice, applying the Machinery Directive 2006/42/EC requires close collaboration among various departments and specialists. Industrial automation plays a key role in ensuring that machines and their components operate in compliance with the directive’s requirements. Companies often utilize industrial automation integrators and engineer outsourcing services for designing and implementing automation systems.
Safety audits and risk analysis according to PN-EN ISO 12100:2012 are crucial stages in ensuring compliance with the directive. Specialized design offices conduct a range of analyses such as strength calculations (FEM), DFMEA, DFA to meet harmonized standards during the machine design or production line design phase. The construction of industrial machines involves multiple stages that must conclude with CE certification and the issuance of an EC declaration of conformity.
User manuals and PLC programming are integral parts of the technical documentation. Proper preparation of these documents is crucial to ensure that users can safely and effectively operate machines compliant with the directive. Automation of production processes and production automation are essential for achieving efficiency and safety in production lines. Implementing advanced technologies and procedures in these areas helps not only in meeting the directive’s requirements but also in improving overall operational efficiency and safety.
The Machinery Directive 2006/42/EC covers a wide range of products that are not machines but are crucial for their safe and efficient operation. Safety components, chains, ropes, belts, incomplete machines, detachable mechanical power transmission devices, interchangeable equipment, and lifting accessories are integral elements that must meet specific requirements to ensure user safety.
Through these regulations, the European Union aims to create a safe and sustainable work environment, minimizing accident risks and promoting the highest safety standards in the machinery industry.
