scope:

This document, intended to be used together with ISO 4254-1, specifies the safety requirements and their verification for the design and construction of

- trailed loader wagons,

- trailed forage transport wagons,

- silage and forage body intended to be affixed to a carrier vehicle,

- trailers with a load push/push-off device, slats or alternating moving floor

which is intended for the use by only one person (operator). In addition, it specifies the type of information on safe working practices including residual risks to be provided by the manufacturer.

This document is not applicable to:

- self-propelled loader wagons and self-propelled forage transport wagons,

- trailers with a tipping body, balanced or semi-mounted, used in agriculture.

When requirements of this document are different from those which are stated in ISO 4254-1, the requirements of this standard take precedence over the requirements of ISO 4254-1 for machines that have been designed and built according to the requirements of this standard.

This document, taken together with ISO 4254-1, deals with all the significant hazards, hazardous situations and events relevant to loader wagons and forage transport wagons, when they are used as intended and under the conditions of misuse that are reasonably foreseeable by the manufacturer (see Annex A). It is not applicable to hazards by presence of other persons than the operator and hazards related to noise and moving parts of the power transmission, excluding strength requirements for guards and barriers.

This document is not applicable to loader wagons and forage transport wagons manufactured before the date of publication of this document.
