Introduction
The extent to which hazards are covered is indicated in the scope of this standard. These hazards are specific
to reel machines for irrigation.
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).
1 Scope
This standard specifies safety requirements and their verification for the design and construction of reel
machines for irrigation including self-propelled machines.
It describes methods for elimination or reduction of risks which need specific requirements for reel machines
for irrigation.
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.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications.
These normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to
this European Standard only when incorporated in it by amendment or revision. For undated references the
latest edition of the publication referred to applies.

3 Definitions
For the purpose of this standard, the definitions given in EN 292-1:1991 and EN 292-2:1991 apply together
with the following:
3.1
reel machine
type of traveller irrigation machine featuring a stationary structure with a reel, coiling a hose which carries
irrigation water to, and drags, a travelling cart, upon which is affixed the emitting system, which is most often
an irrigation gun
3.2
irrigation gun
large sprinkler used on reel machines and other systems
3 3
NOTE The usual flow-rates from guns range from 10 m /h to 100 m /h, and their nozzle diameter from 10 mm to 40
mm.
3.3
coiling
one of the actions performed by the reel machine when irrigating: the reel machine is progressively coiling all
the polyethylene hose on the drum, causing the irrigation gun to move regularly across the irrigation field.
When the irrigation gun reaches the machine, the coiling is completed and the machine stops
3.4
guiding system
lateral guiding device of the hose that permits its steady coiling with joined spirals
3.5
drive system of the guiding system
mechanism providing power to the guiding system that ensures the even layering of the hose
3.6
sweeping zone
envelope of the different positions of the turret corresponding to its different possible orientations
1 - Drum of the spool
2 - Turret
3 - Hose guiding system
4 - Irrigation gun

4 Safety requirements and/or measures
4.1 General
The reel machines for irrigation 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.
4.2 Irrigation gun
The adjustment controls of the irrigation gun that have to be operated during the working (for example
adjustment of the sector angle and of the rotation speed of the irrigation gun) shall be located at a distance
less than 1,80 m from the ground or from the access platform, whatever the speed of rotation of the irrigation
gun.
-1
Irrigation guns with a speed of rotation greater than 1 rad.s shall be located at a height equal to or more than
2 m from the ground or from any platform (vertical distance between the ground or the platform and the lowest
rotating part of the irrigation gun).
This requirement does not apply:
when the swivelling range of the irrigation gun is restricted to a maximum of 300° provided that the
adjustment platform be located outside the swivelling range;
when the irrigation gun is fitted with a guard providing a safety distance in accordance with EN 294:1992.
4.3 Guiding system of hose
-1
When the coiling speed of the hose is greater than 0,4 m.s , access to crushing and shearing points between
the hose and the guiding system and between the guiding system and the frame of the machine shall be
prevented by fixed guards according to EN 953 or by the framework of the machine using the safety distances
according to table 1 of EN 294:1992.
When the uncoiling speed of the hose can be greater than 0,4 m.s-1, access to crushing and shearing points
between the guiding system and the frame of the machine shall be prevented by fixed guards according to EN
953 or by the framework of the machine using the safety distances of table 1 of EN 294:1992.
Access to the drive system of the guiding system shall be prevented by fixed guards according to EN 953.
4.4 Spool
If the rotation of the drum generates crushing or shearing points between the spool and the machine frame,
such points shall be guarded.
Satisfactory methods include for example:
a guard providing the safety distance according to tables 3 and 4 of EN 294:1992;
or
a full (without opening) side wall without any prominent feature including the water delivery pipe between
the axis of the drum and the hose.
Machines equipped with hose speed selector shall be fitted with:

EN 908:1999+A1:2009 (E)
a device which allows for the removal of tension from the hose before changing gear;
or
a device which enables the operator to change gear under tension.
4.5 Stability
Any means needed to ensure stability when working (e.g. jacks, supporting wheels) shall be an integral part of
the machine. They shall comply with 4.3.2.1.1. of prEN 1553:1998.
The machine shall be stable when resting on a slope of 8,5° in the following conditions:
without using the additional means to ensure stability;
hoses full of water and with irrigation gun hooked;
in all the directions of the turret around its vertical axis (if applicable);
with the axle positioned parallel, then perpendicular to the slope.
Any functional outlet of water, associated with the use of the machine, except the possible leakages, shall be
at a minimum distance of 5 m away from the machine.
4.6 Orientation of the turret
If applicable, turrets shall be lockable in both working and transport positions.
The centre of gravity of the mobile part shall be located at less than
