Description of BS EN 703:2021 2021
This document, used together with ENÂ ISOÂ 4254?1:2015 , specifies
the safety requirements and their verification for the design and
construction of mounted, semi-mounted, trailed or self-propelled
machines that have a combination of two or more of the following
functions: loading, mixing, chopping and distributing silage and/or
other feedstuffs or materials used for animal bedding such as
straw, to be used by one operator only. It includes those fitted
with a built-in loading crane. In addition, it specifies the type
of information on safe working practices (including residual risks)
to be provided by the manufacturer.
This document applies only to machines that have the following
functional combinations:
-
mixing and distributing functions;
-
mixing, chopping and distributing functions;
-
loading, mixing and distributing functions;
-
loading, mixing, chopping and distributing functions;
-
chopping and distributing functions; or
-
loading, chopping and distributing functions.
Silage block cutters, even if they carry out a single function,
are covered by this document.
This document does not apply to:
-
machines which pick up green fodder directly from the
field;
-
loading cranes;
-
silage buckets;
-
round or rectangular unbalers.
NOTEÂ 1
Loading cranes are dealt with in
ENÂ 12999:2020 .
NOTEÂ 2
Autonomous silage loading, mixing and/or chopping and
distributing machines (robotic feed systems) will be dealt with
in a separate standard (
ENÂ ISOÂ 3991 , under
preparation).
This document deals with the significant hazards, hazardous
situations and events relevant to machines for loading, mixing
and/or chopping and distributing silage and/or other feedstuffs,
when they are used as intended and under the conditions foreseen by
the manufacturer as listed in Clause 4, except for the hazards arising
from:
-
failure of the control circuit;
-
inadequate seating;
-
inadequate lighting;
-
travelling of machinery;
-
break-up of parts rotating at high speed;
-
cutting hazard during service on sharp parts (e.g. blades of
the mixing and/or chopping device).
It is not applicable to environmental hazards (except
noise).
It does not deal with stability when travelling.
This document is not applicable to machines for loading, mixing
and/or chopping and distributing silage and/or other feedstuffs
which are manufactured before the date of publication of this
