ONR CEN/TS 17471

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.
