Forestry machinery - Wood chippers - Safety

Scope

This document specifies safety requirements and their verification for design and construction of transportable, i.e. self-propelled, mounted, semi-mounted and trailed, wood chippers used in forestry, agriculture, horticulture and landscaping.
This document applies to chippers, used when stationary, which are manually loaded with wood through a horizontal or near horizontal infeed chute at the end of which mechanical infeed components (or chipping components acting as mechanical infeed components) draw the wood into the machine. The included wood chippers may be powered either by an external power source such as a tractor power take-off, hydraulics, etc or by an integral power source such as an internal combustion engine or an electric motor.
This document does not cover:
- requirements relating to national road regulations arising from transport between work sites;
- hazards arising from any self-propelled function;
- hazards arising from the transmission of power from an external power source - e.g. power take-off drive shafts;
- any machines where the infeed chute is fitted with an extension table;
- hazards arising from the engine pull starting of an integral power source;
- hazards arising from mechanical loading;
- vertical infeed chute chippers;
- electromagnetic aspects of the chippers
- shredders/chippers to be covered by EN 13683.
This document deals with all significant hazards, hazardous situations and events relevant to wood chippers, when they are used as intended and under the conditions foreseen by the manufacturer (see Annex A).
In addition, it specifies the type of information to be provided by the manufacturer on the safe use of these machines.
It is not applicable to environmental hazards (except noise).
This document is not applicable to wood chippers which are manufactured before the date of publication of this document by CEN.
