In addition the machines shall be designed to comply with the requirements of #EN ISO 12100$for hazards that are relevant but not significant and therefore are not dealt with in this standard. For the application of the reference standards !deleted text" EN 953, #EN ISO 4413, EN ISO 4414$
!and EN ISO 13732-1"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 working 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. 5.2 Combination of carrier vehicle and machine for highway maintenance SIST EN 13524:2004+A2:2014
EN 13524:2003+A2:2014 (E) 10 The design of the highway maintenance machines shall conform to the requirements of the carrier vehicle defined by its manufacturer. !The assembled machine (carrier vehicle and the attached machine(s)) shall not cause any deterioration in safety provisions such as braking, operator's view, stability during transportation, assembly, use, dismantling and any other action." 5.3 Controls a) Controls of command devices which require a float setting or pressure setting. Controls for elevating and slewing devices shall be designed so that they automatically return to zero position when released. This does not apply to elevating devices that necessitate a float or pressure position or a proportional control according to their function and also does not apply to continuously operating mechanisms such as hydraulic motors. b) Protection against actuation of controls by unauthorized person. Controls shall be lockable by the operator when leaving the workplace by the use of: — guards, or, — mechanical locking means, or, — locking through key-operated switches. c) Controls shall be positioned outside of the hazard zone. Hazardous conditions that are not protected shall be observable by the operator during the operation of the controls. 5.4 Access and walkways Where equipment requiring regular access and walking on is inaccessible from the ground level, access ladders, walkways and standing areas complying with EN ISO 2867 shall be provided. The bottom step or rung of a ladder shall not be more than 650 mm away from the ground level. 5.5 Precautions against hazards caused by moving parts Hazards from moving parts shall be avoided by construction. Access to moving parts shall be prevented by the use of covers conforming to EN 953. If there is a possibility of danger occurring as a result of the operation of the machine or machine components in normal use, no persons shall remain within the danger zone. The manufacturer shall fit warning notices that are easily visible from outside the danger zone, and shall make specific reference to the hazard in the information for use. The danger zone shall be visible to the operator, either directly or by the provision of suitable measures, and information shall be provided in the Information for use. 5.6 Hot surfaces Temperatures of surfaces of machinery with which the operator may come into contact shall conform to
!EN ISO 13732-1". This shall be achieved by the use of guards (e.g. perforated plates placed in front of or around the hot surfaces) or be positioned to avoid unintended risk of contact. Where guarding is impractical, e.g. engine radiator caps, adequate warning signs shall be employed advising on the nature of the risk and avoidance measures shall be described in information for use. SIST EN 13524:2004+A2:2014
EN 13524:2003+A2:2014 (E) 11 5.7 Attachment fittings Attachment fittings on highway maintenance 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. This requirement is satisfied by attachment fittings designed in conformity with Annex B (for front fittings by adapter plates), or with #ISO 730$in conjunction with ISO 11001 (for front and rear attachments respectively using three-point linkage). 5.8 Safety mechanisms for changing machines Safety mechanisms shall be designed to be positively locking and shall be permanently fixed to the machine. 5.9 Lifting devices a) Lifting devices when used as intended shall prevent any unintended lowering of the load1). This requirement shall be achieved by the provision of: — non-return valves or a corresponding function in the control valves of hydraulic or pneumatic lifting devices, or; — self-locking driving gear or an automatic drop-latch arrangement with a ratchet wheel for mechanical winches, or; — a control valve as a back-run safety mechanism. b) Where persons have to stand under raised or tilted machines or components thereof as part of the working procedure2) unintended lowering shall be prevented. This can be achieved, for example, by: — automatically engaging mechanical locks, or; — externally unlocking non-return valves mounted directly on the lifting cylinder, or; — mechanical safety mechanisms which are operated from outside of the danger zone. c) Power-driven lifting devices shall not permit equipment to fall freely in an uncontrolled manner. In hydraulic or pneumatic systems, this requirement is satisfied when the reverse flow is restricted e.g. by a non-return valve or an appropriately sized orifice. d) Back-run safety mechanisms and devices to protect lifting mechanisms against free-fall shall be so designed to ensure that any interference is possible only with the aid of tools. e) Demounting devices for demountable bodywork and components shall be designed and constructed to safely support the equipment during the mounting or demounting process. Power-driven devices shall have a suitable form of synchronisation for the individual lifting elements of supporting equipment. Where these lifting elements are controlled independently of each other, there shall be a locking means for each lifting element (e.g. shut-off valve on the hydraulic cylinder). Where manual jacking systems are used, such as screw jacks, helix angles shall be such that friction locking occurs in any position of the handwheel. #
1) Unintended 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 13524:2004+A2:2014
EN 13524:2003+A2:2014 (E) 12 5.10 Transportation 5.10.1 General$ Machines and movable components shall be provided with means to prevent unintended movements during transportation. The manufacturer shall include details of these means in the Information for use. # 5.10.2 General requirements Parts of the machinery which have to be folded or moved for transportation purpose (e.g. articulated hydraulic arm) shall be designed in such a way that they can be immobilised in order to avoid unexpected movement during transportation. In order to facilitate the removal and installation, the machine shall have appropriate devices for lifting and/or handling (e.g. lifting anchorage point(s), fork-lift device). NOTE The attachment point can be a hole or an eye. 5.10.3 Location of attachment point(s) The lifting attachment point(s) shall be so located in such a way that damage of the lifting accessories due to sharp edges, etc. is avoided when the machine is lifted according to the manufacturer’s instructions. If it is not possible, a specific procedure for lifting shall be described in the operator's manual (e.g. appropriate edges protectors). The lifting attachment points shall be designed in such a way that they will prevent any unintended movement of the lifted part of the machine, taking into account the position of the centre of gravity and the lifting procedure. 5.10.4 Identification of lifting attachment points Lifting attachment points shall be identified adjacent to the points using ISO 6405-1:2004, symbol 7.23, preferably with contrasting colour. Lifting attachment points can also be painted in colour contrasting with the rest of the machinery unit.$ 5.11 Support equipment for machines and components Means of support shall be designed and positioned or be able to be positioned so that the machine can be safety supported on level, stable ground. Means of support 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 means of support cannot carry the gross overall weight of the demounted ma
