Scope

This document specifies requirements with respect to performance and safety for winches that are used in forestry and agriculture for logging and skidding work.

It applies to permanently mounted and removable winches and their components, which are mounted on mobile and self-propelled forestry machines as defined in ISO 6814:2009, as well as to winches for forestry mounted on agricultural tractors or other implements that are used for forestry work. This document also applies to capstan winches and winches using driving sheaves or driving pulleys and portable winches used for forestry.

It applies exclusively to winches that are used for dragging loads on horizontal and inclined ground during logging operations, which are used for unspooling and positioning of the winch rope of another winch for forestry or which are used to support tree felling work.

It does not apply to winches:

— that are used for hoisting or lifting operations;

— that are used in draglines;

— that are used in yarders;

— designed for traction aid purposes;

— using ropes made from natural fibres

— using operating and control voltages > 60 V;

— that are used with log splitters according to EN 609-1.

Control systems for winches with fully or partially self-evolving behaviour or logic are not covered by this document.

The significant hazards included in this document are identified in Annex A.

This document is not applicable to winches manufactured before the date of its publication.
