ANACAM MAGAZINE - n. 2 aprile | giugno 2021
39 alle norme UNI EN 81 arrivarono le norme UNI 10411 che contenevano i criteri di buona tecnica per la modifica o so- stituzione di parti di ascensori elettrici rispondenti a norme preesistenti alla norma UNI EN 81-1. Un susseguirsi di nor- me, di aggiornamenti ed emendamenti, sino alla rivoluzio- ne culturale della Direttiva Ascensori in vigore dal 1999. Il progettista, quindi, come detto, stava via via assumendo un ruolo sempre più di guida all’interno dei meandri della nor- me, aiutando la ditta artigiana a scegliere la miglior strada per realizzare un impianto nuovo, o modificato, secondo le norme vigenti. I “castelli”, al contempo, non erano più delle strutture metalliche “a servizio” del nuovo impianto ma co- minciavano ad essere considerate delle vere e proprie strut- ture edilizie che necessitavano di verifiche strutturali non più solo statiche ma anche sismiche. Le disposizioni antisi- smiche previste dalla Legge n. 64 del 1974, infatti, confluiro- no, con alcune modifiche, nel DPR 6 giugno 2001, n. 380, e successivamente, nella nuova normativa sismica introdotta dall’ordinanza n. 3274 del 2003 e dai successivi decreti del 14 gennaio 2008 e del 17 gennaio 2018. Così tra DIA, SCIA, CILA, relazioni geologiche e Genio Civile, il nostro amato “progettino” era diventato l’ultimo passaggio di un iter mol- to più lungo e complesso. Al contempo la successiva evo- luzione delle norme della serie UNI EN 81 sino alle ultime UNI EN 81-20 e UNI EN 81-50, al fianco della serie UNI 10411, ha costretto tutti, dai progettisti agli installatori e ai manutentori, ad instaurare un continuo scambio di infor- mazioni virtuoso per mettere in servizio ascensori a regola d’arte. Questa profonda evoluzione della progettazione, in questi ultimi 50 anni, è stata seguita passo passo dall’ANA- CAM con i continui incontri formativi ed informativi cui hanno sempre preso parte ascensoristi e progettisti e oggi, ancora di più, emerge la sua funzione indispensabile. later equally fascinated me. At the end of the 1980s, I became acquainted with a software that I have never left: Autocad R10. This is probably how the romantic era of design ended, the drawing table began to tilt more and more until it became a horizontal table for folding drawings; production times for drawings and reports began to shorten and we became slaves to the computer and the plotter. However, something had not changed: the relationship between the customer and the engineer. The systems were still “customized” and the lift companies still assembled their systems by choosing the components they preferred. Although the standards became more and more detailed, each lift continued to be “different” from the other and the designer chose the characteristics of the gearbox, guides, ropes and any other component based on the customer’s needs. But something was changing, even artisans were slowly adapting to the needs of the market: so the role of the designer also began to change. The human factor, unfortunately, was losing its value. The “assembled” lift was replaced by the “complete” lift, produced by a single supplier. The change came from Europe and not only for new installations but also for maintenance. In fact, in the mid-90s, the UNI 10411 standards arrived along with the UNI EN 81 standards, which contained the criteria for the modification or replacement of electric lifts parts that comply with pre-existing standards to the UNI EN 81-1 standard. A series of rules, updates and amendments, up to the cultural revolution of the Lift Directive in force since 1999. Therefore the designer, as mentioned above, was gradually taking on an increasingly leading role within the web of rules, helping the artisan firm to choose the best way to build a new or modified system, according to current regulations. The “castles” were no longer metal structures “at the service” of new lifts but were beginning to be considered real building structures that needed structural checks, that were both static but seismic. The anti-seismic provisions provided for by Law no. 64 of 1974, in fact, merged, with some modifications, into the Presidential Decree of the 6th June 2001, n. 380, and subsequently, in the new seismic legislation introduced by ordinance no. 3274 of 2003 and the subsequent decrees of January 14, 2008 and January 17, 2018. Therefore with the different kind of building permits, geological relations and Civil Engineering Department’s authorization, our beloved “zippy project” had become the last step of a much longer and complex process. At the same time, the ensuing evolution of the standards of the UNI EN 81 series up to the latest UNI EN 81-20 and UNI EN 81- 50, alongside the UNI 10411 series, forced everyone, from designers to installers and maintenance technicians, to establish a constant information exchange to set up state of the art lifts. ANACAM was part of this profound evolution of design over the last 50 years, by providing unceasing training and updating in meetings which lift operators and designers have attended, and today its crucial function is more evident then ever.
