1 Dakofa 2014 Rasmus Banke Banke Accessory Drives Agenda Lidt om Banke Accessory Drives Baggrund og produkter Meldgaard og Ringkøbing-Skjern kommune idriftsætter landets første Gas/El-hybrid Skraldebiler Støj, Arbejdsmiljø og Brændstofbesparelser Test og Dokumentation Fordele / ulemper / Økonomi Fremtiden Inden- og Udenlandske erfaringer En opfordring 1

2 Banke - Accessory Drives Produktet gør det muligt at drive en lastbils arbejdsfunktioner med el, som et alternativ til at drive dem med dieselmotoren og et traditionelt kraftudtag. Electrical Power Take-Off (E-PTO) Udviklingsprojektet Eldrevne Arbejdskøretøjer 2

3 Nye Udviklingsprojekter Deltager i meldgaard miljøs projekt Den Hybride Skraldebil under CFGT Deltager Acemu med Aalborg universitet (nye batteriteknologier) Lead partner I europæisk projekt under Fornyelsesfonden Berliner Stadt Reinigung Amsterdam Kirchoff Gruppe Zoeller Faun Semat Haller Lead Partner Emocrane under Energistyrelsen Sauer-Danfoss Syddansk Universitet Produktet 3

4 E-PTO kan kombineres med alle chassistyper + ca. 40 andre skraldebiler 7 2 nye støjsvage gasbiler til Ringkøbing-Skjern 4

5 Støjreduktion Delta 2000/14/EU: Noise emission in the environment by equipment for use outdoors 9 TC Page 9 of 14 Støjreduktion og arbejdsmiljø lydtrykket over tid reduceres med 75%! Powered by Engine Battery LWA1 (Engine max speed) LWA2 (compaction) LWA3 (lifting device) LWA4 (Material falling) LWA4* (Material falling, LpAeq,T) Summery. Measured sound power levels for the 4 operating modes defined by 2000/14/EC. LWA4* is calculated on basis of LpAeq,T instead of LpA,1s. [db re 1 pw] The resulting sound power level is calculated according to 2000/14/EC by: 25% LWA sound power level 'A' rated, an EU rating system commonly applied to machinery etc. Powered by Engine Battery LWA (according to 2000/14/EC) LWA* (on basis of LpAeq,T, not acc. to 2000/14/EC) Comment: Because LWA4 is calculated on basis of LpA,1s (=SEL, Sound Exposure Level) the sound 5

6 Støjreduktion og arbejdsmiljø Arbejdstilsynets bekendtgørelse nr 63 af 6 februar 2006 (Direktiv 2003/10/EC of 6/2 2003) omhandler minimumsforskrifter for sikkerhed og sundhed i forbindelse med arbejdstagernes eksponering for risici på grund af fysiske agenser (støj) Den internationale standard ISO 1999 omhandler forbindelsen mellem støj og risikoen for høreskader. 11 Støjreduktion og arbejdsmiljø Et støjniveau på 85 db (A) svarer til: 85 db(a) i 8 timer 88 db(a) i 4 timer 91 db(a) i 2 timer 94 db(a) i 1 timer 97 db(a) i 30 minutter 11. Ingen må udsættes for støjbelastning over 85 db(a) eller spidsværdier af impulser over 137 db(c). Hvor værdierne overskrides, skal der straks træffes foranstaltninger, der bringer støjen under værdierne, ske en fastlæggelse af årsagerne til, at værdierne overskredet, og træffes tekniske og organisatoriske foranstaltninger for at undgå, at overskridelsen gentages. 12 6

The garbage handling lasts for 10 minutes with the operation modes distributed as 6% engine at max speed, 53% compacting, 40% lift handling without garbage, and 1% with falling garbage. Støjen reduceres til ¼ for beboerne, hvor skraldebilen opererer. Annex 2 Example of of noise noise contribution It is assumed that the average time (reference period) is 30 minutes corresponding to the Danish noise regulations for the night period.
