EN 13021:2003+A1:2008 (E) 5 Introduction This European Standard is a Type C-standard as stated in !EN ISO 12100". The machinery concerned and the extent to which hazards are covered is indicated in the scope of this standard. !When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this European Standard." 1 Scope This European Standard applies to winter service machines which are defined in clause 3. This European Standard deals with all significant hazards (see clause 4) identified through a risk assessment pertinent to winter service machines when they are used as intended and under the conditions foreseen by the manufacturer. This European Standard does not deal with significant hazards associated with !deleted text" EMC. This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards associated only with machine operation, setting and adjustments, load discharge and routine maintenance. Winter service machines are normally mounted on carrier vehicles (e.g. trucks, tractors, construction machinery and mobile industrial handling equipment). This European Standard does not cover requirements for the carrier vehicles even where specific modifications have been made to realise the winter service application. These requirements will be handled in directives and standards for the construction of carrier vehicles. The use of winter service machines in public road traffic is governed by national regulations. This standard does not cover any requirements for demountable bodywork systems (e.g. demountable containers). These requirements are specified in other standards. This European Standard does not deal with:  machines or components which are solely designed for clearing rails such as rail sweepers or blowers;  walker-operated and hand-held winter service machines;  highway maintenance machines covered by !EN 13524", such as front-mounted sweepers;  machines for the maintenance of sports grounds;  machines for agriculture, horticulture and forestry;  machines intended for use in potentially explosive atmospheres. This European Standard applies to winter service machines which are manufactured after the date of approval of the standard by CEN. SIST EN 13021:2004+A1:2009

SIST EN 13021:2004+A1:2009



EN 13021:2003+A1:2008 (E) 10 For the application of the reference standards !EN ISO 13732-1", EN 953, EN 982 and EN 983 which are used in this standard, the manufacturer shall carry out an adequate risk assessment relating to those requirements for which a special safety measure or -category is necessary. NOTE This specific risk assessment should be part of the general risk assessment relating to the hazards not covered by this standard. Where the means of reducing the risk is by a safe system of operating the machinery, the manufacturer shall include in the information for use details of the system and of the elements of training required by the operating personnel. 5.1 Design as regards handling !and compatibility with the carrier vehicle" 5.1.1 Attachment fittings Attachment fittings on winter service machines shall be designed so that during the actual coupling and de-coupling action nobody is required to be in the hazard zone between the components concerned. NOTE This requirement can be satisfied by attachment fittings designed in conformity with annex B (for front fittings by adapter plates), or with ISO 730-1 in conjunction with ISO 11001 (for front and rear attachments respectively using three-point linkage). 5.1.2 Locking devices Mechanical locking devices shall be designed to have positive engagement and to be connected with the machine so that they can not be lost. 5.1.3 Elevating equipment a) Elevating equipment shall be constructed or designed so that during intended use any lowering of the load1) is prevented.
This requirement shall be achieved for example by the provision of:  check valves or similar functions within the control valves of hydraulic or pneumatic lifting equipment; or,  self-locking actuators or automatically engaging latches in arrangement with a ratchet wheel for mechanical winches; or,  control valves as reverse-flow prevention mechanism. Non-return valves (burst pipe protection) mounted directly on the lifting cylinder are not necessary unless workmen have to move underneath raised or tilted machine components as part of working procedure2); or,  other locking devices conforming to 5.1.2. b) If persons have to enter beneath elevated machines or machine components when used as intended and under conditions foreseen by the manufacturer (e.g. maintenance, clearing, inspection) it is necessary to prevent unintended lowering of the elevated parts by providing safeguards, for example, by:  automatically engaging mechanical locking devices; or  pilot check valves integrated into the lifting cylinder; or
1) Accidental lowering is when a load runs back or descends because of an interruption or an irregularity in the energy supply.
2) The term "as part of working procedure" does not cover repair work. SIST EN 13021:2004+A1:2009



EN 13021:2003+A1:2008 (E) 11  mechanical locking devices which are operated from outside of the hazard area. c) Powered lifting devices shall be equipped to eliminate the possibility of equipment returning in free fall.
In hydraulic or pneumatic systems, this requirement shall be satisfied when the reverse flow is restricted by a non-return valve or an appropriately sized orifice. d) Access to safeguards against return and free fall of lifting means shall be possible only with the use of tools. e) Demountable attachments and equipment shall be so designed and constructed that they can be mounted and dismounted safely.
Powered systems shall incorporate a suitable form of synchronisation of the individual lifting elements of a lowering device. Where lifting elements are controlled independently of each other, each shall be provided with an interlock (e.g. shut-off valve on the hydraulic cylinder). Manually actuated lifting systems shall select the pitch of the spindle thread such that it is self-locking in every spindle position. f) The manufacturer shall include in the information for use details of the safe working practices to be observed and the elements of training to be provided to the operators. 5.1.4 Slewing devices Moving and slewing shall be by a controlled movement. Unintentional movements of slewing devices and uncontrolled movements of components of winter service machines shall be prevented. Mechanical locks or appropriate valves in hydraulic or pneumatic actuated systems may be used to achieve a controlled movement. 5.1.5 Support equipment for machines and components Supporting means shall be designed and positioned or be able to be positioned so that the machine can be safely supported on level, stable ground. Supporting means shall be connected to the machine by means of positive engagement. The distance between the support legs shall be dimensioned to permit safe movements of the carrier vehicle during the mounting and demounting process. Where the supporting means cannot carry the gross overall weight of the demounted machine (structural weight plus effective load) it shall be clearly marked with the maximum load which can be supported. Warning signs shall be fixed visible to the operator drawing attention to the need to check that the load to be supported does not exceed the maximum load which can be supported. Supporting means employed for moving the machinery when demounted shall be fitted with equipment that prevents any unintentional movement in the unattended condition. The manufacturer shall provide advice on safe working practices for the use of the supporting means in the information for use. 5.1.6 Disconnectable power and signal-transmitting systems Disconnectable power and signal-transmitting systems shall be provided with suitable connecting elements appropriate to their operating environment. Disconnectable hydraulic fluid power systems shall be provided with suitable, self-sealing coupling elements. If several coupling elements are grouped in a location, it shall be ensured that incorrect connections do not give rise to a hazardous situation. This can be achieved e.g. by providing non-interchangeable connections or by using unambiguous, permanent markings. SIST EN 13021:2004+A1:2009
