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.

This document specifies the general safety requirements for demountable machines and trailers, including road-rail trailers - henceforward referred to as ‘machines, for use when travelling and working on railway track.
NOTE   Trailers, including road-rail trailers, are considered as machines because they are moved along the track by powered machines.
This document specifies the requirements to deal with the common hazards presented by their use on the railway during transport, assembly and installation, commissioning, travelling and working on track, use including setting, programming, and process changeover, operation, cleaning, fault finding, maintenance and de-commissioning of the machines and associated equipment when they are used as intended and under conditions of misuse which are reasonably foreseeable.
These machines will not run on railway lines open to normal traffic.
NOTE   Other rail mounted railway maintenance and infrastructure inspection machines are dealt with in other European standards, see Technical Report CEN/TR 17498:2020.
This document is also applicable to machines and associated equipment that in working mode are partly supported on the ballast or the formation.
The requirements in this document are based on the assumption that the machines are used, operated and maintained by skilled person(s).
This document does not apply to the following:
-   requirements for quality of the work or performance of the machine;
-   use of separate equipment temporarily mounted on machines;
-   machines that utilize external power supplies such as the overhead contact line system for traction purposes or as a power source;
-   hazards due to air pressure caused by the passing of high-speed trains at more than 200 km/h;
-   operation subject to special rules, e.g. potentially explosive atmospheres;
-   hazards due to natural causes, e.g. earthquake, lightning, flooding;
-   working methods;
-   operation in severe working conditions requiring special measures, e.g. corrosive environments, contaminating environments, strong magnetic fields;
-   hazards occurring when used to handle suspended loads which may swing freely.

This document specifies the concept phase of the development of safety-related parts of control systems (SRP/CS) on tractors used in agriculture and forestry and on self-propelled ride-on machines and mounted, semi-mounted and trailed machines used in agriculture. It can also be applied to mobile municipal equipment (e.g. street-sweeping machines).
This document is not applicable to:
— aircraft and air-cushion vehicles used in agriculture;
— lawn and garden equipment.
This document specifies the characteristics and categories required of SRP/CS for carrying out their safety-related functions. It does not identify performance levels for specific applications.
NOTE 1 Machine specific type-C standards can specify performance levels (AgPL) for safety-related functions in machines within their scope. Otherwise, the specification of AgPL is the responsibility of the manufacturer.
This document is applicable to the safety-related parts of electrical/electronic/programmable electronic systems (E/E/PES), as these relate to mechatronic systems. It covers the possible hazards caused by malfunctioning behaviour of E/E/PES safety-related systems, including interaction of these systems. It does not address hazards related to electric shock, fire, smoke, heat, radiation, toxicity, flammability, reactivity, corrosion, release of energy, and similar hazards., unless directly caused by malfunctioning behaviour of E/E/PES safety-related systems. It also covers malfunctioning behaviour of E/E/PES safety-related systems involved in protection measures, safeguards, or safety-related functions in response to non-E/E/PES hazards.
Examples included within the scope of this document:
— SRP/CS's limiting current flow in electric hybrids to prevent insulation failure/shock hazards;
— electromagnetic interference with the SRP/CS;
— SRP/CS's designed to prevent fire.
Examples not included within the scope of this document:
— insulation failure due to friction that leads to electric shock hazards;
— nominal electromagnetic radiation impacting nearby machine control systems;
— corrosion causing electric cables to overheat.
This document is not applicable to non-E/E/PES systems (e.g. hydraulic, mechanic or pneumatic).
