In the world of technical standards, . It signifies access to an official, authenticated, and legally recognised version of the document directly from a national standards body.
For critical attachments such as vacuum lifters, the standard requires a design. This means the system must be capable of safely holding the load even if one component fails. The safety factor for such systems is calculated by considering the worst‑case single failure scenario.
Self-priming and non-self-priming vacuum lifters, as well as permanent, electric, and electro-permanent lifting magnets. Structural Elements: Lifting beams and spreader bars.
Electromagnets require battery backup systems to hold the load for a minimum specified time if primary power fails. din en 13155 pdf exclusive
Must feature a counterweight design that tilts the hook backward when unloaded, ensuring the lip safely retains the coil during engagement. 3. Special Requirements for Vacuum and Magnetic Lifters
Lifting insert systems specifically for normal-weight concrete. Key Safety Requirements

The amendment introduced several significant changes. These include a revised introduction and updated normative references, as well as revised definitions for key terms such as 3.7, 3.22, 3.25 and 3.26. Tables 1–8 and Table 10 have also been revised, along with large portions of Sections 5, 6 and 7. Furthermore, Annexes A, C, D, E, H and ZA have been editorially reworked.
Comprehensive testing protocols are laid out, including static load tests (verifying strength under rated load and overload conditions), dynamic load tests (simulating real-world conditions such as lifting, lowering, vibration, and shock), functional tests (verifying specific functions like magnet holding force or vacuum integrity), and material property tests (tensile, bending, impact, and chemical composition analysis).
The standard applies to detachable attachments that can be fitted to a crane hook or other lifting devices. Key covered items include: Clamping Devices: Plate clamps and other various clamps. Vacuum Lifters: This means the system must be capable of
— Depending on the type and usage intensity, a safety inspection should be carried out at regular intervals, but at least once a year. For high‑risk or heavily used attachments, a visual inspection every four months is recommended, supplemented by non‑destructive testing (e.g. crack detection) every 12 months.
Battery-powered lifting magnets must have a warning system to signal low battery capacity, ensuring the magnet does not fail mid-lift. 3. Tilting and Stability Limitations
DIN EN 13155 is a critical European standard that specifies the safety requirements for non-fixed load lifting attachments. These are the devices used to attach a load to a crane hook (e.g., plate clamps, vacuum lifters, magnetic lifters, grabs, and C-hooks).
Powered or non-powered devices that use negative pressure (suction) to hold and lift flat, non-porous materials like glass panels or sheet metal. 3. Magnetic Lifters
