Introduction
This document is a type-C standard as stated in ISO 12100:2010.
This document is of relevance, in particular for the following stakeholder groups representing the
market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organisations, market surveillance etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events
are covered are indicated in the Scope of this document. When requirements of this type-C standard are
different from those which are stated in type-A or type-B standards, the requirements of this type-C
standard take precedence over the requirements of the other standards for machines that have been
designed and built according to the requirements of this type-C standard.
Traction aid winches are used with forest machines when operating in sloped terrain and on soils with
limited bearing capacity or poor traction. Such winches do provide traction aid to a supported machine.
The combined tractive effort provided by the machine’s wheels or tracks and the traction aid winch
makes it easier to access steep slopes and manage unfavourable soil conditions while maintaining
productivity by avoiding excess uphill driving or driving around a gradient, especially with harvesters,
fellers, forwarders and skidders. Forest floor damages are greatly reduced which leads to a lower
risk of erosion after logging operations. Machine stability is also enhanced, and thus general safety of
operation is improved. Traction aid winches offer a possibility for machines to work on slopes which
otherwise would be difficult to negotiate. This makes it simpler to mechanize work in steep terrain
which otherwise would have to be performed manually.
Forestry winches for typical logging, such as the ones used for skidding or cable yarding of stems/logs,
are designed for a different application than traction aid winches. The control systems, safety features,
and performance measures of forestry winches have been designed for a purpose that is incompatible
with the requirements of traction aid applications. Therefore, forestry winches should not be used in
traction aid applications.
The main categories of winches for tractive efforts are shown in Figure 1. Further aspects of the design
and operation of traction aid winches can be found in Annex E.
