As you requested a review exclusive to you, I assume you're interested in accessing the DIN EN 13155 PDF. You can obtain a copy of the standard from various sources, including:
Legitimate PDFs issued by DIN are DRM-protected but allow printing. If a PDF lets you copy-paste entire chapters without a digital certificate, it is likely a forgery.
Before mass production, a prototype of the lifting attachment undergoes static and dynamic load testing. This guarantees that the design meets the calculated safety margins under controlled stress conditions. Individual Testing
Electromagnets require battery backup systems to hold the load for a minimum specified time if primary power fails.
The standard does not end with the manufacturer; it also imposes duties on the end user.
Additionally, the standard does not cover slings, ladles, expanding mandrels, buckets, grabs, grab buckets, or power‑operated container handling spreaders (which fall under EN 15056).
Specialized hazards from explosives, radioactive elements, or molten metal.
Any attachment that relies on friction or suction (like clamps or vacuum lifters) must have secondary safety mechanisms. For vacuum lifters, this usually involves a visual or audible warning system to alert the operator if the vacuum level drops below 80%. 3. Stability and Tilting

The standard applies to a wide range of lifting equipment designed for overhead cranes, mobile cranes, and other lifting machinery. It covers attachments used for: Clamps, grabs, scissor grabs, tongs.
| Category | Specific Types | |---|---| | | For lifting steel plates and similar materials. | | b) Vacuum lifters | Self‑priming and non‑self‑priming (pump, venturi, turbine). | | c) Lifting magnets | Electric (battery‑fed and mains‑fed), permanent lifting magnets, and electro‑permanent lifting magnets. | | d) Lifting beams | Spreaders, load‑rotating beams and other lifting frames. | | e) C‑hooks | For handling coils and reels. | | f) Lifting forks | Designed to slide under loads. | | g) Clamps | General clamping devices for lifting. | | h) Lifting insert systems | For use in normal‑weight concrete (as defined in Clause 3). |

is a key European safety standard governing the design and testing of non-fixed load lifting attachments for cranes and hoists. The current version, DIN EN 13155:2022-03 , covers various attachments, including vacuum lifters, magnets, plate clamps, and lifting beams. Key Requirements & Scope
DIN EN 13155 is built on a foundation of rigorous safety principles. The most critical technical requirements revolve around three key areas:
