Stroji za gradnjo predorov - Odkopne naprave - Varnostne zahteve
EN 12111 določa vsa resna tveganja, nevarne situacije in dogodke, povezane z odkopnimi napravami iz točke 3, pri predvideni uporabi in v pogojih, ki jih je predvidel proizvajalec. Kjer je navedeno, ta standard velja tudi za rezalne glave in udarne vrtalnike, pritrjene na bagre in v tunelskih ščitih. Ta standard določa ustrezne tehnične ukrepe za odpravljanje ali zmanjšanje tveganj, ki nastanejo pri resnih tveganjih. V okviru pogojev, ki jih je določil proizvajalec, prevrnitev odkopne naprave ni resno tveganje. Hrup ni resno tveganje pri rezalnih glavah. Zgoraj omenjeni bagri in tunelski ščiti niso vključeni v ta standard in jih obravnavata standarda EN 474+A1 in EN 12336+A1. Evropski standard prav tako obravnava razumno predvidljivo napačno uporabo teh strojev, pri čemer upoštevanje zahtev iz točke 5 zmanjšuje tveganje, ki se pojavi pri takšni napačni uporabi. Ta evropski standard ne obravnava naslednjih predmetov in uporab: - oskrba glavne stikalne škatle z električno energijo; - uporaba stroja v potencialno eksplozivnih ozračjih; - uporaba stroja v nizkotlačnih okoljih; - oprema za natovarjanje in prevoz, ki ni sestavni del stroja. Ta evropski standard zajema nadzorovanje nevarnih atmosfer. Ta evropski standard se ne uporablja za stroje, izdelane pred datumom izdaje tega evropskega standarda s strani CEN.

In addition, they shall be designed according to the principles of EN ISO 12100 for hazards relevant but not significant which are not dealt with by this European Standard. 5.2 Specific requirements 5.2.1 Contact surfaces 5.2.1.1 Sharp corners and edges Accessible parts of machines shall be designed and manufactured to minimize sharp edges, angles or rough surfaces which are likely to cause injury, see ISO 12508. 5.2.1.2 Hot surfaces Where there is a risk of contact with hot surfaces in accessible areas, suitable measures shall be taken: — to limit the temperature of hot surfaces, see EN ISO 13732-1; — where this is not possible, to prevent contact with those surfaces/parts by screens or guards; — to provide warning signs against residual risks, see 5.12. This requirement does not apply to the excavation tools. 5.2.2 Stability The manufacturer shall ensure the machine does not undergo any uncontrolled movements when operated in accordance with the conditions intended by the manufacturer. The limits of controlled movement shall be stated in the instruction handbook. This shall be achieved by having a sufficiently heavy machine or by the use of grippers. The maximum permissible longitudinal and transverse slopes on which the machine can be operated shall be defined in the instruction handbook (see 7.3.1). To ensure stability during assembly, the manufacturer shall provide information on assembly sequence in the instruction handbook. SIST EN 12111:2014
14 5.2.3 Ladders, access ways and platforms The manufacturer shall define in the instruction handbook the areas of the machine to which access is required to operate, service and maintain the machine (see 7.3.1). Access to these areas of machine shall be provided in accordance with EN ISO 14122-1, EN ISO
14122-2, EN ISO
14122-3 and EN ISO 14122-4. Ladderways or stairways shall be provided to give access to control stations, servicing points and working platforms. Where not directly accessible from the ground, working platforms shall be provided at servicing points including filters, pumps, motors, lubricating points, battery compartments and fluid storage tanks. Where this requirement cannot reasonably be applied to the discharge conveyor, a temporary means of access, e.g. hydraulic access platform or ladder, will be required and the manufacturer shall record this in the instruction handbook – see 7.3.1. 5.3 Control station 5.3.1 General requirements The machine shall be controlled from a control station on the machine or by remote control (see 5.5.8). Where it is always intended to control the machine remotely, a control station on the machine is not required. Where a machine has more than one starting control for any function, key switches shall be fitted to ensure only one starting control is active at any time. The control station shall be dimensioned in accordance with EN ISO 3411. When there is a control station on the machine it shall be ergonomically designed in order to minimise operator fatigue and stress. Consideration shall be given to the fact that operators may wear personal protective equipment. The control station if provided shall have a seat for the operator. It shall comply with the requirements of
EN 474-1:2006+A4:2013, be adjustable, retain the operator in a stable position and allow the operator to control the machine under all expected operating conditions. For seat dimensions see ISO 11112. Arm rests or other means shall be provided to ensure safe operation of sensitive controls (e.g. hold-to-run controls). The seat shall be designed to minimise transmission of vibration to the operator. See EN ISO 7096. 5.3.2 Falling objects and ejected material The control station shall be protected by location or guarding e.g. by deflector plates, against spoil rolling down the cutter arm, boom or conveyor. The control station shall be protected against falling objects and materials ejected from the cutter head. Protection against falling objects shall be by falling object protective structure (FOPS). The FOPS shall comply with level II of EN ISO 3449. NOTE The scope of EN ISO 3449 excludes road headers and continuous miners. However for road headers and continuous miners the requirements of EN ISO 3449 are equally applicable as for earth-moving equipment. Protection against ejection of materials shall be by guarding of the cutter head or the provision of a protective structure or the use of reinforced glass or similar transparent material at the control station. The means of protection shall not reduce the operator’s visibility. 5.3.3 Cab 5.3.3.1 General A cab shall be provided fulfilling the following requirements: — ventilation with adequate dust filtration and where applicable, heating and/or cooling; — isolation from airborne noise and structure-borne noise; SIST EN 12111:2014
