HL820ST ni hydraulic yo hejuru ya nyundo yo mu bwoko bwa nyundo, yagenewe cyane cyane DL311 na DL321 munsi yubutaka bwimbitse

Imyitozo ya HL820ST ya hydraulic yamashanyarazi yashizweho kugirango harebwe ubushobozi bwo gucukura cyane, kubungabunga byoroshye nigiciro gito cyo gukora.Imiterere yimyitozo ya rutare ishingiye ku module nyamukuru ihujwe hamwe na bine bigufi;Ibi byemeza byibuze umubare uhuriweho hamwe nubunini bunini bwo guhuza.Ingaruka module iroroshye mugushushanya kandi igizwe nibice bibiri byimuka: piston hamwe nogukwirakwiza amaboko hafi ya piston.Ibice byimuka ntabwo bihura na module yimyitozo yumubiri.

HL820ST ifite stabilisateur ihindura imbaraga zingaruka zoguhindura imiterere yimiterere yigitare, kwemeza guhuza amabuye meza no guhererekanya ingufu, kuzamura igipimo cyogucukura nubuzima bwibikoresho byubutare.

Hano hari moteri ebyiri zizunguruka kugirango zuzuze urumuri ruzenguruka hamwe na RPM ibisabwa kugirango aperture zitandukanye hamwe nubutare.Amashanyarazi atabishaka akoreshwa mukuboko cyangwa guhita ufungura ibikoresho bya rock mugihe ukoresheje umwobo umwe cyangwa automatike.Igishushanyo cya HL820ST gikubiyemo ibintu byinshi.
