EN 12999:2011/FprA1

(Amendment)

Cranes - Loader cranes

Cranes - Loader cranes

Starting to apply EN 12999:2011, it becomes evident that there are two safety related issues where the current writing is unsatisfactory. First issue is addressed in clauses 5.4.3.1 and 5.6.1.3. These clauses deal with the requirement of indication when the boom system is not stowed in its transport position. The two clauses are now ambiguous and can be interpreted to be in contradiction. The intention when revising EN 12999 was that it for all vehicle mounted loader cranes should be required and sufficient to indicate when the angle of the first boom is out of its transport position. The two clauses should be amended to be unambiguous. Second issue is addressed in clause 5.4.1.2. This clause deals with the stabiliser feet and requires that they shall adjust to a 10° ground slope. This requirement is unsafe for timber handling cranes. These cranes often work with one leg down on the steep slope of a ditch. There, a fixed foot embeds firmly in the soft soil, whereas a tiltable foot easily slides down the slope. The clause should be amended to provide a safe requirement also for timber handling cranes. A new work item is needed to make these amendments. The work item should follow the 3 months UAP path.

CEN/TS 17471:2024(Main)
Cranes - Loader cranes - Interface between loader cranes and work platforms
SIST-TS CEN/TS 17471:2024

This document specifies technical requirements for the interface of the basic machinery within the scope of EN 12999 equipped to allow the use of an assigned type of work platform as interchangeable equipment where the combination of the basic machinery and the work platform as interchangeable equipment is within the scope of EN 280-1.
The basic machinery covered by this document is designed to be installed on a road vehicle with load carrying capability. The combination of the basic machinery and the work platform as interchangeable equipment covered by this document belongs to Group B Type 1 class as in the scope of EN 280-1.
The basic machinery covered by this document allows two modes of operation:
-   the “CRANE” mode of operation, for the use of the basic machinery as a loader crane within the scope of EN 12999;
-   the “MEWP” mode of operation, for the use of the work platform with the basic machinery as within the scope of EN 280-1.
This document covers hazards related to switching between “CRANE” and “MEWP” mode as described above and covers the specific hazards related with the combination and the assembly of the work platform as interchangeable equipment with the basic machinery (see Annex A).
This document does not address hazards which may occur:
a)   when using work platform not assembled with the lifting machinery but simply lifted by the machinery (e.g. suspended from the hook of the crane);
b)   when using attachments not intended for the lifting of persons.
