Abstract (fin):Dieselgeneraattorilla syötetyissä nostureissa polttoaine on merkittävä kustannus nosturioperaattoreille.
Diplomityössä tarkastellaan nostokoneistoon liitetyn energiavaraston tarjoamia mahdollisuuksia nosturin polttoaineenkulutuksen pienentämiseksi sekä superkondensaattoreihin perustuvan energiavaraston toteuttamismahdollisuuksia.

Työssä pohditaan erilaisista energiavaraston ohjausmenetelmistä saatavia etuja ja energiavaraston mitoitusperusteita erilaisilla ohjausmenetelmillä.
Päätavoitteena on energiankulutuksen ja asennettavan generaattori-kapasiteetin pienentäminen.
Energiavaraston käyttäytymistä nosturissa mallinnetaan todellisessa käyttötilanteessa mitattujen ajosyklien avulla.

Energiavaraston todetaan pienentävän tehokkaasti nostokoneiston energiankulutusta, mutta säästön merkitys nosturin polttoaineen-kulutukseen havaitaan pieneksi.
