26、machinery lying within the scope of Directive 2006/42/EC, the “Machinery Directive”, as well as for machinery lying outside the scope of this directive. This standard deals with the safety of machinery within the meaning of the Machinery Directive, has been drawn up along the lines of CEN Guide 414,

27、 and is a “type C standard”. The purpose of the standard is to ensure a consistent level of safety as regards the planning, construction, design, maintenance and inspection of machinery installations for use in staging and production facilities in the entertainment industry, taking into consideratio

28、n the operations particular to such facilities. The present standard thus contains verifiable criteria for tendering procedures and for the inspection of machinery installations . In the new EU Machinery Directive (Directive 2006/42/EC) the previous term “theatre elevators” has been replaced by the

29、expression “machinery intended to move performers during artistic performances”. Such machinery is excluded from the scope of the new Machinery Directive, which is implemented in Germany by the 9. Verordnung zum Produktsicherheitsgesetz (Maschinenverordnung 9. ProdSV) (9th Ordinance of the German Pr

30、oduct Safety Act (Machinery Ordinance 9th ProdSV). However, such machinery is not only used to “move performers during artistic performances”, but also to move or hold loads over persons, and to more or hold the persons themselves, not only during “artistic performances”, but also during stage const

31、ruction, setting up scenery, and rehearsals. The aim of this standard is to provide a consistent level of safety also for machinery which is excluded from the Machinery Directive. Machinery installations can in certain circumstances also be classed as “work equipment” in the sense defined in the Bet

32、riebssicherheitsverordnung (BetrSichV) (German Ordinance on Industrial Safety and Health). DIN 56950-1:2012-05 7 1 Scope This standard applies to machinery and machinery installations used in places of assembly and in staging and production facilities for events and theatrical productions (stage mac

33、hinery, for short). Such facilities include: theatres, multi-purpose halls, exhibition halls; film, television and radio studios; facilities in: concert halls, schools, exhibition halls, bars, discotheques, open-air stages and other rooms for shows and events. For the purposes of this document, mach

34、inery installations are all technical installations and equipment used for operations in stage and production facilities in the entertainment industry. Such installations are used to lift, lower, suspend and carry loads (e.g. scenery, traverse systems, or lighting, film/video and sound equipment). T

35、hey may also be used to move persons, and persons may stand under such equipment while the loads are at rest or in motion. This standard applies to machinery and machinery installations with guided or unguided load bearing and load carrying equipment. Typical machinery installations include but are

36、not limited to the following: auditorium elevators; cycloramas; fly bar systems (manual, motor driven); guiding tracks; lighting bars; movable lighting towers; movable stage platforms (stage wagons); movable proscenium arches; orchestra elevators; performer flying systems; point hoists; portable sca

37、ffolds; projection screens (manual or motor-driven); revolving stages and turntables; scenery storage elevators; side stage and rear stage shutters; stage elevators; stage wagons (stage trucks); tiltable stage floors. DIN 56950-1:2012-05 8 This standard also applies to safety-related equipment used

38、to protect against imminent hazards and which are used for similar safety purposes in the facilities listed above. Examples of safety-related equipment include: smoke extractors; safety curtains. For safety-related equipment the safety functions take priority. This standard also applies to machinery

39、 installations based on new technologies or specially designed installations which are not expressly mentioned here but which nevertheless operate in an identical manner to the equipment listed above. This standard does not apply to: machinery installations which are used for artistic purposes only,

40、 or to manual hoists (load capacity 20 kg, with the load being either uniformly distributed or concentrated (point load) NOTE A distinction is made between manually operated flying systems (e.g. manual counterweight systems) and motor-driven systems (e.g. with electric or hydraulic drive) 3.1.6 poin

41、t hoist lifting equipment having one load bearing line for lifting, lowering, and suspending loads 5 kg, where the load is concentrated (point load) 3.1.7 “Schleppboden” (suspended lift platform) platform which is not permanently fixed to the load bearing device (stage elevator) and whose distance t

42、o the fixed platform of the stage elevator does not remain constant, and which serves as an additional device for bearing the load 3.1.8 securing device mechanical device which prohibits unintentional movements EXAMPLES: Brakes, shut-off valves 3.1.9 structural element element between the load carry

43、ing device and the point of attachment within the machine limits, which bears both the load and the self-weight, including dynamic forces, of the machine, and which is permanently fixed to the machine 3.1.10 load bearing equipment lifting equipment, including the drive mechanism, which bears loads 3

44、.1.11 drive system part of load bearing equipment that executes the raising, lowering and holding motions 3.1.12 stage elevator stage lift part of a horizontal or inclined (tilted) stage, performance area, studio or auditorium floor which can be moved vertically up and/or down, including all necessa

45、ry drive elements EXAMPLE 1 Elevator which is a permanent part of the stage, performance area, studio or auditorium floor (e.g. orchestra elevator, single- or double-deck stage elevator, stage compensating elevator, scenery storage elevator or auditorium elevator). EXAMPLE 2 Elevator which is not a

46、permanent part of the stage, performance area, studio or auditorium floor, which is used primarily for scenic purposes and which normally rests below stage (e.g. stage trap elevator).
