This document gives safety requirements, and the means of verification, for the design and construction of mobile yarders for logging of forest products and their mounting. It counts for all logging operations with cable yarders both in sloped and flat terrain. In addition, it specifies the type of information on safe working practices (including residual risks) meant to be provided by the manufacturer. It deals with the significant hazards (as listed in Table 1), hazardous situations and events relevant to mobile yarders used as intended and under the conditions of misuse foreseeable by the manufacturer (see Clauses 4 and 5). Emission of noise (with regard to airborne noise) is not covered by this document. It is not applicable to: – rope splicing; – ancillary loaders or cable cranes; – cableways for material transport (other than wood); and – skidder winches (skidding). The specifications of cabin in this context are only relevant for the yarder or a yarder-loader combination. The cabin and the chassis of the vehicle (prime mover), to which the yarder is mounted are not part of this document. This document is not applicable to mobile yarders manufactured before the date of its publication.<\/p>\n
