Skavatur li jappoġġja l-grab idrawliku tal-injam
Il-grabs idrawliċi tal-injam huma magħmulin prinċipalment minn apparati mdendlin, ġonot rotanti, ċrieki li jduru, bolsters, ċilindri idrawliċi, u valvi tal-barmil.Il-korp tal-barmil u r-raġġ tal-bearing t'isfel huma konnessi b'xaft tal-pin;it-tarf tal-pistun taċ-ċilindru taż-żejt huwa ffissat fuq il-bolster, u l-virga tal-pistun hija mwaħħla fuq il-parti ta 'fuq tal-valv tal-barmil. Peress li l-virga tal-pistun taċ-ċilindru tiġi rtirata u estiża, il-korp tal-barmil idur bil-pin tal-pin tal-bearing kif punt taċ-ċappetta, li jlesti l-ftuħ u l-għeluq tal-barmil tal-grab.Il-grabs tal-injam idrawliċi jintużaw ma 'skavaturi u mhumiex imħaddma minnhom infushom, billi jiddependu fuq iż-żejt idrawliku bi pressjoni għolja pprovdut mill-iskavatur bħala sors ta' enerġija.L-iskavatur jiġbed żejt idrawliku bi pressjoni għolja fis-sistema tal-ftuħ u l-għeluq tal-grab, u jikkontrolla l-ftuħ u l-għeluq tal-grab billi jikkontrolla l-estensjoni u l-irtirar taċ-ċilindru.
