1. Mtundu wamtundu wa hydraulic system pa Volvo G740 grader umazindikira kuyenda bwino kwa ntchito zonse zamakalasi kudzera pa spool yapadera mu valavu yayikulu.Pa liwiro lililonse ntchito, dongosolo akhoza kulamulira mbale mpeni m'malo bwino, mofulumira ndi ndendende.Makina oyendetsa magudumu onse a motor grader ali ndi njira yokwawa, yomwe imangogwiritsa ntchito mphamvu ya hydraulic kuyendetsa mawilo akutsogolo kuti ayende, kupititsa patsogolo kulondola kogwira ntchito.Njirayi ndiyoyenera kwambiri pakuwongolera bwino, chifukwa mawilo akumbuyo a tandem amangogubuduza opanda mphamvu ndipo sangawononge nthaka yomwe yangoyimitsidwa.
2. Yotsimikiziridwa ndi ROPS/FOPS, kabati ya G740 motor grader ndi yotakata, yokhala ndi mawonekedwe a 360-digrii yozungulira komanso mawonekedwe a chipangizo cha ergonomic control, kotero kuti woyendetsa akhoza "kuwongolera".Malo aukhondo komanso omasuka a cab, njira zowongolera mawu a cab ndi makina oziziritsira mpweya amathandizira kuchepetsa kutopa kwa oyendetsa ndikuwongolera magwiridwe antchito komanso magwiridwe antchito.
Mayendedwe aulendo wa grader yamagalimoto amayendetsedwa ndi chiwongolero chokhala ndi kuwongolera kwakukulu.Zachidziwikire, wogwiritsa ntchito amathanso kugwiritsa ntchito chosankha chowongolera kuti achepetse ntchito.Kupititsa patsogolo chitetezo ndi kuwongolera, mawotchi owongolera nthawi zonse amakhala patsogolo kuposa makina osangalatsa, zomwe zimalola woyendetsa kukonza nthawi yomweyo.Dongosolo la joystick limaperekanso Articulation Steering "Park in Neutral Function" yomwe imatha kutsegulidwa ngati kuli kofunikira kubwezera chiwongolero cha motor grader ndendende pamalo osalowerera ndale kudzera pa sensa.
3. G740 motor grader ili ndi injini yaposachedwa ya D8 komanso kufala kwapamwamba kwambiri pamakampani.Kutumiza kwa 11-speed kumapereka ntchito zambiri ndi maulendo oyendayenda, kupatsa wogwiritsa ntchito kusinthasintha kuti asankhe zida zogwiritsira ntchito bwino mafuta malinga ndi momwe zimagwirira ntchito.Kutumiza kumeneku kwakonzedwanso kuti kuzitha kuzizirira komanso kukhala ndi mawonekedwe odziyimira pawokha kuti musunthike bwino komanso mogwira mtima komanso kuti ntchito ichuluke.Ingosunthani chiwongolero cha giya m'mbuyo ndi mtsogolo kuti musunthe mumayendedwe okhazikika opanda malire, ndipo mutha kusintha mwachangu pakati pa zida zilizonse zakutsogolo ndi zida zosinthira popanda kufooketsa chopondapo kapena kukonza chopondapo.Dongosolo la V-ECU limangosintha ma transmission kuti asalowerere kuti injini isayime.
4. Pofuna kukulitsa kuchuluka kwa zida zogwiritsira ntchito, mapangidwe a G740 motor grader amaganizira bwino za kusavuta komanso kuthamanga kwa kukonza.Kuwunika tsiku ndi tsiku ndi kukonza magawo sikufuna zida zilizonse.Mulingo wamafuta ukhoza kuwonedwa ponseponse komanso kudzera muzitsulo za cab;kukonza fyuluta ya mpweya wa cab kungatheke pansi kunja kwa galimoto;madoko oyendera a zigawo zina zonse amatha kutsegulidwa ndi kiyi yoyambira injini yomweyo.Ziwalo zina ndizosakonza, monga chotenthetsera chowongolera kutentha cha zigawo zofunika, ndipo gawo loziziritsa limatha kudziyeretsa lokha pobwezeretsa.
Ngati makina opangira ma motor nthawi zina angafunike ntchito yopitilira kuwunika ndi kukonza nthawi zonse, akatswiri aukadaulo a Volvo ali okonzeka kupereka chithandizo kwamakasitomala kudzera pamaneti ogulitsa padziko lonse lapansi.Kutengera chidziwitso chapadziko lonse lapansi komanso chidziwitso chapadziko lonse lapansi, Volvo imapatsa ogwiritsa ntchito mayankho osiyanasiyana kuchokera ku zida zosinthira zenizeni kupita kuukadaulo wapamwamba wowunika makina, ndipo yadzipereka kuchepetsa mtengo wonse wogwirira ntchito ndikuwongolera magwiridwe antchito pa moyo wonse wa zida.
