Iyo PPPC (Proportion Priority, Pressure Compensation) control valve yakanyatsogadzirwa neCaterpillar yemagetsi graders inogovera simba maererano nezvinodiwa uye kuyerera maererano nechiyero, kuve nechokwadi chokuti mutyairi anogona kushandisa muchina kuti apedze zviito zvemusanganiswa zvakawanda uye zvakanyanya kuvandudza kushanda kwekushanda.Iyo inochinjika displacement plunger pombi inoshandiswa kuderedza kurasikirwa kwesimba, kuderedza kupisa kunogadzirwa neiyo hydraulic system, uye kuderedza kushandiswa kwemafuta.Kuremerwa-kunzwa hydraulics inopa kufanofungidzira, kwakanyatso kuita mafambiro ekuvandudza kunaka kwebasa uye kubudirira.Iyo PPPC valve ine yakavakirwa-mukati yevhavhavhavha yekuvhara mukati memukati wevhavha core, kuchengetedza chinzvimbo chemuchina chishandiso kana pasina hydraulic oparesheni, uye chengetedza hutano hwebasa;kudzivirira kufamba netsaona kwechishandiso chemuchina uye kudzivirira kukuvara netsaona kune vashandi.
6. Bhokisi-yakaumbwa dhizaini yekugadzira neflange inochengetedza nzvimbo yepamusoro-soro kubva kune weld seam, iyo inovandudza kuvimbika uye kusimba uye inowedzera hupenyu hwebasa rezvikamu zvekugadzirisa.Iyo inoenderera kumusoro uye pasi peplate chimiro chinopa simba rakanaka rinoenderana uye rinoenderana zvizere nezvinodiwa zvekugadzira zveCaterpillar's structural parts, izvo zvinogona kurebesa hupenyu hwemberi furemu uye kuderedza mutengo wekushandisa.Mapombi akarongedzerwa padivi pefuremu yepamberi kuitira nyore kugadzirisa.Zvikamu zvakakosha zvinoshandisa self-lubricating bushings kuvandudza kuvimbika uye kuderedza mari yekugadzirisa.
7. Iyo cab inowanikwa pamberi pechigadziko, uye nzvimbo ye traction frame, turntable uye blade inogona kuonekwa zvakajeka, iyo inobatsira kuti mutyairi atonge nzvimbo ye blade zvakanyatsonaka.Yakareba uye yakapamhama (1.9 metres kumusoro), inogona kuvhiyiwa yakamira, uye huwandu hwayo i30% yakakura.Kutungamira kwemavhiri epamberi kunogona kunyatsoonekwa kana chiuno chakakotama, kuve nechokwadi chekuchengetedza uye nekururama kwekushanda.
