Cais:

1. Offer mecanyddol mawr: megis generaduron mawr, offer dur, offer adeiladu llongau ac offer arall sy'n gofyn am gapasiti llwyth uchel a gweithrediad sefydlog.
2. Offer metelegol: Yn addas ar gyfer melinau rholio, sgriniau dirgrynol a pheiriannau castio parhaus yn y diwydiant metelegol.
3. Offer Mwyngloddio: Fe'i defnyddir ar gyfer malu offer, sgrinio offer a chyfleu offer yn y diwydiant mwyngloddio.

Nodweddion:

1. Capasiti llwyth uchel: Oherwydd ei faint mawr a'i strwythur cryf, mae gan y dwyn NNU4956 gapasiti llwyth rhagorol a gall wrthsefyll llwythi rheiddiol ac echelinol uchel.
2. Perfformiad cyflym: Mae'r dwyn wedi'i beiriannu'n fanwl a'i optimeiddio i addasu i gymwysiadau cylchdroi cyflym a chynnal nodweddion gweithredu sefydlog.
3. Anhyeredd Uchel: Mae gan y dwyn NNU4956 allu anhyblygedd a gwrth-ddadffurfiad uchel, a gall gynnal safle sefydlog a rheolaeth safle manwl gywir.
