Afrigy zvinodiwa zveCramende-yakaiswa canes panguva yekutyaira: Zvinodiwa zvekusimudza kusimudza

In the realm of truck-mounted crane operations, kuchengetedzeka ndeyekuchinja kwakanyanya mukufamba kwese kwekutyaira. Pakati pezvakadzika nzvimbo dzekuchengetedza, the stability of truck-mounted cranes stands out as a crucial consideration. Kuverengera kugadzikana kwemashini ane simba aya kwakakosha kudzivirira tsaona uye kuchengetedza hutano hwevashandi nevaya vari padyo. Saka, Ndezvipi chaizvo zvinodiwa kuti zviitwe? Zvino, Iye Munyori anopa rondedzero yakadzama yevaridzi vekadzi.

During the lifting operation of truck-mounted cranes, Zvinhu zvinoverengeka zvinogona kutyisa kusimbisa. Kusimudza zvinhu zvakazara njodzi yakakosha. Kana crane achiedza kusimudza chinhu chinodarika chaicho chakarukwa, inogona kunetsa zvinhu zvemakhini uye kudzikisira kugadzikana kweiyo yese system. Uremu hwakawandisa hunogona kuisa zvakanyanya kusagadzikana pane boom, chassis, uye zvimwe zvinhu zvekugadzira, Kuwedzera mukana wekusagadzikana uye zvinogona kupunzika.

Zvikanganiso zvekuita zvinogona kutungamirawo kune yakawandisa inertial simba. Semuyenzaniso, Kana iyo opareta yakangoerekana yawedzera kana kusimbisa iyo boom panguva yekusimudza, Inogona kuburitsa simba rine simba risingakanganisi iro rinogona kukanganisa chiyero che crane. Saizvozvowo, Kubata zvisina kunaka kwekutonga kana kuti nekukurumidza kufamba kunogona kukonzera mutoro wekutsvedza zvisina kufanira, Kuwedzera kudzikisira crane.

Kugovera kwemusoro wekutsigira kune kumwe kunetseka. Kana crane ikasimudzwa pane isina kugadzikana kana yakapfava pasi, kurema kweiyo crane uye mutoro kusimudzwa kunogona kukonzera iyo inotsigira nzvimbo yekunyura. Izvi zvinogona kuguma mukugoverwa kusingaenzaniswi kwehuremu uye kurasikirwa kwekugadzikana. Muzviitiko zvakanyanyisa, Kudya kunogona kuve kwakanyanya zvekuti crane secples pamusoro.

Excessive wind force is yet another factor that can affect the stability of truck-mounted cranes. Mhepo dzakasimba dzinogona kupa simba rakakosha rakareba pane boom uye iyo yakazara crane chimiro. Kana iyo crane isina kuchengetedzwa zvakanaka kana kana mhepo kumhanya kupfuura iyo crance's dhizaini miganhu, Inogona kusundirwa kunze kwehuremu uye kunyange kupfuudza.

For wheeled and truck-mounted cranes, Nekuda kwemamiriro avo ezvivakwa, Pasinei nekuti ndebvu dzakashandiswa kana dzisiri panguva yekushanda, Iyo ine njodzi isina kugadzikana mamiriro ekushanda apo boom iri muchimiro perpendicular kune iyo rutivi rwakatambanudzwa mutsara wemuviri wemotokari. Uku kuronga kunoisa iyo inoshamisa mhedzisiro yemutoro uye mhepo mauto, kugadzira iyo crane yakawanda ichimhan'arira. Naizvozvo, Kana uchifunga kugadzikana kweiyo cranne uye kuitisa kugadzikana bvunzo dzekupinda uye kubuda, mamiriro ekushanda ane boom iri kumberi inotorwa seyakawana. Pasi pemamiriro ezvinhu ekushanda aya, Iyo crane inofanira kunge ine mashoma yakavimbiswa kugadzikana kuve nechokwadi chekushanda kwakachengeteka.

The lifting capacity of wheeled and truck-mounted cranes is not only determined by the stability of the whole machine but also controlled by the strength of the boom. Iko kusarudzwa kweiyo boom chikamu chimwe chinhu chakakomba che crane dhizaini. Iyo inoverengwa maererano neimwe mamiriro ekushanda, izvo zvinowanzoitika zvine urefu hwakareba, amplitude, uye inoenderana inosimudza uremu. Vagadziri vanofanirwa kuve nechokwadi chekuti boom inogona kutsungirira mauto akashandiswa nemutoro pasina buckling kana kukundikana.

Kana iyo boom chikamu chinotemwa, Iyo yekusimudza uremu pasi pehupfumi hwakasiyana uye amplitunts yakaverengerwa zvichienderana nesimba iripo yeiyo boom. Iyi process inoguma nekusikwa kwekusimudza uremu-amplitude curve, inozivikanwa sesimba rinosimudza hunhu. Yakareba boom kureba inoburitsa seti yemakireti akasiyana, yega yega inomiririra yakachengeteka kusimudza kugona kweimwe gadziriso.

Different types of truck-mounted cranes have different strength lifting characteristic curves. Iyi curves yakaiswa chiratidzo pane Signboard mukabati kuti upe ruzivo rwakakosha kune anoshanda. Mutyairi anofanira kushandisa crane mukuenderana akaenderana nezvinodiwa zve curve. Kuomerera kune aya nhungamiro kunovimbisa kuti crane haina kuwandisa uye kuti boom inoshandiswa mukati menguva yayo yakachengeteka yekushanda.

Dzimwe crames dzakashongedzerwa neAlarm zvishandiso zvekuwedzera kuchengeteka. Aya ma alarm akagadzirirwa kurira kana crane ichisvika kana inodarika miganhu yayo yakachengetedzeka. Ivo vanogona kuona zvinhu zvakadai sehuremu hwakawandisa, zvisina kunaka boom angle, kana yakakwira mhepo kumhanya uye chenjererwe inoshanda kuti utore kururamisa chiito. Nekupa chaiyo-nguva mhinduro, Aya ma alarm midziyo anobatsira kudzivirira iyo crane kubva pakuremerwa uye kuderedza njodzi yengozi.

Sezvingaonekwe kubva pamusoro, Kuti uve nechokwadi chekusimudza kusimudza kwe crane, Mutyairi anofanira kutevedzera zvakanyatsogara nenzira dzekuchengetedza mashandiro. Izvi zvinosanganisira nokungwarira kuongorora iyo mutoro usati wasimudza, Kuverengera kuti crane yakaiswa pane yakagadzikana inotsigira nzvimbo, uye kushanda zvinodzora nekunyora uye kungwarira. Izvo zvinorambidzwa chaizvo kushandisa crane yakakurisa kana kutenderera zvinhu zvinorema pakumhanya kwakanyanya. Kufuratira crane kunogona kutungamira mukukasira kutadza uye kusagadzikana, Paunenge uchitenderera zvinhu zvinorema pakumhanya kwakanyanya kunogona kuunza yakawandisa centrifugal simba, izvo zvinogona kukonzera iyo crane kuti uwedzere.

Semuyenzaniso, imagine a truck-mounted crane operator who ignores the safe lifting limits and attempts to lift a load that is too heavy. Sezvo crane inotambudzika kutsigira uremu hwakawandisa, Iyo boom inogona kutanga kukotama, uye chassis inogona kuve isina kugadzikana. Iko kunetseka kwakawedzerwa pazvinhu zvemakhinji zvinogona kutungamira kukundikana kamwe kamwe, zvichikonzera crane kujekesa uye zvinogona kukonzera kukuvara kwakanyanya uye kukuvara.

Pane rimwe divi, Kana iyo inoshanda inotenderera mutoro unorema pakumhanya kwakanyanya, iyo centrifugal simba inogona kusundira crane kubva kune chiyero. Iko kamwe kamwe kuchinja kwekugovera uremu kunogona kukonzera kuti vabvekere kuti vasimudze pasi kana mota kune skid, zvichikonzera mamiriro ezvinhu ane njodzi.

Kuti udzivise zviitiko zvakadaro, operators must be thoroughly trained in the safe operation of truck-mounted cranes. Ivo vanofanirwa kunzwisisa izvo zvisingakwanisi kumidziyo, ziva nesimba kusimudza hunhu curves, uye ziva nzira yekupindura kune dzakasiyana siyana njodzi. Kugara kuchengetedzwa uye kuongorora kwe crane kwakakoshawo kuve nechokwadi chekuti zvikamu zvese zviri mumamiriro akanaka ekushanda uye kuti zvinhu zvekuchengetedza zviri kushanda zvakanaka.

Mukupedzisa, ensuring the lifting stability of truck-mounted cranes is a complex task that requires a combination of proper design, Kudzidziswa kweOperator, uye kuomerera kune maitiro ekuchengetedza maitiro. Nokunzwisisa uye kusangana nezvinodiwa kuti zvigadziriswe, Vashandi vanogona kuderedza njodzi yengozi uye vimbisa kushanda kwakachengeteka uye kwakaringana kwemishini iyi ine simba.
