In this technical article, we will explore the standards and specifications outlined in the EN 1152-2011+A1:2015. This standard sets forth requirements for the design and manufacture of escalators and moving walks, providing safety guidelines and performance criteria.
1. of EN 1152-2011+A1:2015
The EN 1152-2011+A1:2015 is a European standard that covers the construction and installation of escalators and moving walks used for passenger transportation. It specifies safety requirements, dimensions, and operational characteristics to ensure the user's safety and comfort.
This standard includes provisions for various components, such as drive mechanisms, braking systems, handrails, steps or pallets, and control systems. It also covers topics like load tests, electrical requirements, emergency stop devices, and fire protection.
The primary objective of EN 1152-2011+A1:2015 is to prevent accidents during normal operation and in foreseeable abnormal situations. Compliance with this standard minimizes potential risks, enhances user safety, and promotes long-term reliability of escalator systems.
2. Key Requirements and Specifications
EN 1152-2011+A1:2015 defines specific parameters and criteria that manufacturers and installers must adhere to when designing, manufacturing, and installing escalators and moving walks.
One of the crucial requirements is ensuring the structural integrity of the equipment. The standard outlines strict guidelines regarding load-bearing capacities, impact resistance, and stability under various operating conditions and loads.
Additionally, the standard highlights the importance of safety features, including emergency stop devices, handrail monitoring systems, and smooth leveling operations. Manufacturers must ensure that escalators and moving walks comply with these safety provisions to mitigate potential risks.
Moreover, the standard specifies requirements for electrical systems, including insulation, grounding, and protection against power supply interruptions. It also covers control systems, emphasizing features like fault diagnostic capabilities, drive performance, and energy efficiency.
3. Compliance and Certification
Compliance with EN 1152-2011+A1:2015 is crucial for manufacturers, installers, and maintenance companies involved in escalator and moving walk projects within Europe. These entities must ensure that their products meet the stipulated requirements before placing them on the market.
To demonstrate compliance, manufacturers can undergo a conformity assessment procedure whereby they assess and declare that their products satisfy all applicable provisions of the standard. This process involves various testing, documentation, and inspection activities conducted by accredited third-party organizations.
Once the conformity assessment process is successfully completed, manufacturers receive a Declaration of Conformity, which certifies that their product complies with the EN 1152-2011+A1:2015 standards. This certificate demonstrates the product's adherence to safety regulations and helps gain the trust of customers and authorities.
In conclusion, the EN 1152-2011+A1:2015 serves as a vital regulatory framework for ensuring the safe design, manufacture, installation, and use of escalators and moving walks across Europe. By adhering to this standard, manufacturers can enhance user safety, prevent accidents, and deliver reliable and high-quality equipment.
