Agricultural machinery - Pick-up balers - Safety
This standard specifies safety requirements and their verification for design and construction of self-propelled and trailed pick-up balers independent of the shape or size of the bales formed.
It describes methods for the elimination or reduction of risks which need specific requirements for pick-up balers. It does not deal with hazards which are common to all agricultural machines particularly common hazards related to mobility, including those specific to self-propelled machines. These aspects will be dealt with in another standard produced by CEN/TC 144 (see introduction).
In addition, it specifies the type of information on safe working practices to be provided by the manufacturer.
The list of significant hazards dealt with in this standard is given in annex A. Annex A also indicates the hazards which have not been dealt with.
Environmental aspects have not been considered in this standard.
This standard applies primarily to machines which are manufactured after the date of issue of the standard.
Landmaschinen - Sammelpressen - Sicherheit
Diese Norm enthält sicherheitstechnische Anforderungen und deren Überprüfung für Gestaltung und
Konstruktion von selbstfahrenden und gezogenen Sammelpressen, unabhängig von der Form und den Abmessungen
der hergestellten Ballen.
Sie beschreibt Maßnahmen zur Vermeidung oder Verminderung von Gefährdungen, für die spezifische Anforderungen
an Sammelpressen benötigt werden. Sie behandelt keine allgemeinen Gefährdungen, besonders
nicht die allgemeinen Gefährdungen aufgrund der Beweglichkeit, einschließlich die von selbstfahrenden
Maschinen. Diese Punkte werden in einer anderen Norm behandelt, die vom CEN/TC 144 erstellt wird (siehe
Einleitung).
Außerdem gibt sie Informationen über sicheres Arbeiten, die vom Hersteller zur Verfügung zu stellen sind.
Die Liste der signifikanten Gefährdungen, die in dieser Norm angesprochen werden, ist in Anhang A
aufgeführt. Der Anhang A weist auch auf die Gefährdungen hin, die nicht behandelt wurden.
Die Umweltaspekte wurden in dieser Norm nicht in Betracht gezogen.
Diese Norm gilt in erster Linie für Maschinen, die nach dem Ausgabedatum der Norm hergestellt worden sind.

Introduction
The extent to which hazards are covered is indicated in the scope of this standard. These hazards are specific
to pick-up balers.
The hazards that are common to all the agricultural machines (self-propelled, mounted, semi-mounted and
trailed) will be dealt with in a standard currently in preparation (prEN 1553).

3 Safety requirements and/or measures
3.1 General
The machinery shall comply as appropriate with EN 292 for hazards which are not dealt with and especially
with annex A of EN 292-2:1991/A1:1995 when EN 292 does not give precise requirements.
Unless otherwise specified in this standard, the machine shall comply with the requirements of prEN
1553:1998 and with tables 1, 3, 4 and 6 of EN 294:1992.
3.2 Requirements for all types of balers
3.2.1 Protection against hazards related to moving power transmission parts
To ensure protection against hazards related to accessible moving power transmission parts, the machine
shall be fitted with fixed guards (according to 3.22.1 of EN 292-1:1991).
When frequent access is foreseen, the machine shall be fitted with guards needing a tool for their opening.
These guards shall remain attached to the machine when opened (for example by means of hinges) and
automatically lock in the closed position without the use of a tool.
If this type of guard is not used, the machine shall be fitted with:
interlocking movable guards (according to 3.22.4 of EN 292-1:1991); or
movable guards fitted with a device which prevents their opening so long as the parts are moving.
3.2.2 Drawbar
When the drawbar has separate positions, for transport and for working, it shall be provided with a mechanical
or hydraulic locking device that requires an intentional action to change from transport to working position and
from working to transport position (e.g. pin, latch or hydraulic cylinder). When a hydraulic device is used, the
drawbar shall remain locked in position if the hydraulic circuit fails.
3.2.3 Pick-up device
The protection of exposed persons against unintentional contact with any of the accessible moving parts at
the front and at the sides of the pick-up device shall be ensured by a combination of barriers and fixed parts of
the machine. The projection on a horizontal plane of these protective devices shall be continuous (see figures
1 and 2).
When the pick-up device is in the working position, these barriers shall be:
a minimum of 230 mm in front of the most forward point of the tine path and at a height h of between 500
mm and 1 000 mm above the ground (see figure 1);
a minimum of 150 mm from the sides of the tine path at a maximum height above the ground of 500 mm
(see figure 1). If the tine path is totally covered by a part of the machine when viewed from the side (see
figure 2), this barrier is not required.
NOTE 1 The strength of the barriers will be dealt with within prEN 1553.

3.2.4 Feeding elements
Crushing and shearing points located at a distance of less than 550 mm from the outer limit of the machine or
from the extreme edges of the feeding channel shall be guarded according to 3.2.1.
3.3 Requirements for rectangular balers
3.3.1 Flywheel
Accessible parts of the flywheel shall be guarded according to 3.2.1.
If the flywheel guard is open underneath, a distance of at least 25 mm shall be provided between the flywheel
and the guard; this 25 mm shall
