Cov txheej txheem tsim ntawm cov log loaders tau undergone ze li ib puas xyoo ntawm cov tsheb laij teb, kev ua haujlwm yooj yim, kev txawj ntse, thiab kev tsim qauv me me.
Cov ntsiab lus tseem ceeb tau nyob rau ntawm kev ua haujlwm tseem ceeb ntawm cov khoom tseem ceeb xws li cov cuab yeej ua haujlwm, kev xa cov kab mob, thav duab thiab cab.
(1) Kev tshawb nrhiav thaum ntxov ntawm lub tsheb laij teb uas muaj tsheb laij teb (1920s-1940s): Cov Qauv Pib Thaum pib ua
Lub hom phiaj tsim ntawm theem no yog los tshem tawm kev cia siab rau ntawm kev siv zog ua haujlwm thiab tsim lub cim yooj yim ntawm cov log loaders. Xyoo 1920, tus thawj loader tau hloov kho los ntawm cov tsheb laij teb ua liaj ua teb, nrog mast ntxiv rau sab pem hauv ntej los kho lub lifting hydraulic kheej kheej.Lub thoob tau txuas nrog cov boom ntawm ib lub latch, cia siab rau lub ntiajteb txawj nqus rau tipping thiab kev thauj khoom; Tus qauv muaj kev sib cav.
Los ntawm 1939, tus them nyiaj los ntawm Hawker Corporation hauv Tebchaws Meskas tau los ua tus sawv cev ntawm 0.255 mp, haum rau kev thauj khoom lub teeb lub teeb.
Kev txhim kho txheej txheem txuas ntxiv
sas ceev. Xyoo 1941, tus tsav tsheb lub tsheb ciav hlau tau txav mus rau sab xub ntiag kom pom kev pom zoo, thiab lub cav tau hloov mus tom qab thiab hloov nrog lub cav diesel.
Xyoo 1944, hydraulic kis tau hloov cov tsoos hlau cable tswj rau lub thoob, txhim kho kev tswj hwm precision.
Xyoo 1947, plaub-}} log tsav cov qauv tshwm sim, ua kom lub hauv paus sab nraud, tso cov qauv txheej txheem rau tom ntej hnyav- Destion ua haujlwm.
(2) theem tseem ceeb rau lub tsheb laij teb uas muaj log (1950s-1970s): Cov Txheej Txheem Txheej Txheem Tshiab thiab nthuav dav thaj tsam
Cov txheej txheem kev tsim qauv ntawm cov theem no tsom rau kev txhim kho kev ua haujlwm thiab yoog ua rau muaj kev ua haujlwm sib txawv. Muaj ob peb tus qauv tseem ceeb ua kev tsim kho cov khoom lag luam los ntawm cov khoom siv rau cov khoom siv txua khoom lag luam.
Xyoo 1950, lub log loger nrog lub tshuab hydraulic torque hloov tau.
Cov qauv no tso cai rau hauv cov khoom siv tau yooj yim dua, kev ua haujlwm nrawm nrawm thiab hloov pauv cov drawbacks kiag li. Nyob rau hauv 1960s, articulated qauv los ua cov qauv tsim qauv. Cov qauv no zoo heev txhim kho kev ua tau kauj ruam, txhim kho kev ua tiav, thiab ntev ruaj khov.
Lub peev xwm 7.6mling lub peev xwm ua tiav articulated loader, qhia nyob rau xyoo 1965, ua tiav tau nkag mus rau qhov qhib- lub qhov puting kev lag luam.
Xyoo 1970 pom ib qho kev tsim kho dual rau cov qauv hloov dua thiab me me loader.
Piv txwv li, American Clark 675 Loader khav tawm ntawm 1000kw thiab lub peev xwm thoob plaws 16m³, thaum Japanese 310 loader muaj lub zog tso zis ntawm tsuas yog 9.8KW.
Qhov kev sib txawv no hauv cov txheej txheem teeb meem tso cai rau kev yoog raws li cov kev ua haujlwm ua haujlwm.
(3) paub tab thiab ua kom zoo ntawm lub log tsheb kauj vab (1980s- xyoo pua 21st): Kev sib xyaw ua ke
Nyob rau theem no, tus qauv tsim qauv tau pib teeb tsa hluav taws xob hauv tshuab hluav taws xob, thaum tseem yuav tsom mus rau kev ua kom zoo dua cov neeg siv kev ntseeg tau thiab kev ntseeg tau. Thaum xyoo 1980s, kev khawb tawm loaders tau qhia thiab nruab nrog rau cov tshuaj xyuas hluav taws xob, pub rau tiag {2} Taug kev taug qab cov txheej txheem kev ua haujlwm.
Tom qab cov 1990s, Mechatronics thev naus laus zis tau siv dav.
Kab Ntsig Dusters ntxiv cov microcomputer saib xyuas mus rau lub cab, nrog rau cov thoob tswj cov kauj vab, piv rau cov txheej txheem kev ua haujlwm.
Komatsu wa series loaders siv Silicone roj hmab siv cov khoom siv tsav tsheb hauv tsheb, txo qis {% -50%.
Cov qauv tsim qauv ntawm lub sijhawm no tsis muaj kev txwv tsis pub ua haujlwm tab sis kuj pom tias tus neeg tsav tsheb nplij siab. Nyob rau tib lub sijhawm, kev sib koom ua ke ntawm cov tshuab hluav taws xob thiab cov qauv siv tshuab txo qhov tsis ua haujlwm.
(4) Kev hloov pauv niaj hnub ntawm cov log tsheb kauj vab (21st xyoo los nthuav qhia): kev nce qib xyoo nyob rau hauv kev txawj ntse, nthuav dav, thiab modularization, thiab modularization, thiab modularization, thiab modularization, thiab modularization, thiab modularization, thiab modularization, thiab modularization, thiab modularization, thiab modularization, thiab modularization, thiab modularization, thiab modularization, thiab modularization, thiab modularization, thiab kev hloov kho
Tam sim no, tsim qauv tsim ntawm whased loaders tseem hloov kho ib ncig ntawm cov hom phiaj ntawm kev ua haujlwm siab thiab txuag hluav taws xob, kev kho kom yooj yim.
Txhua lub Cheebtsam tseem ceeb tau ua tiav hauv - qhov tob ua kom zoo:
1.Ua haujlwm ntaus ntawv thiab lub xcmg xc956 pro loader adops a z {{1} pa regersible rau- tus qauv.Lub pob hinge taw tes yog cae optimized, thiab nws yog nruab nrog dual {{}}}}}}}} Koj tuaj yeem muab cov khoom siv tau yooj yim. Kab ntsig Tshiab tiam ntawm cov qauv yog nruab nrog cov khoom siv ua haujlwm pabcuam uas cia li txoj haujlwm ntawm qhov siab ntawm qhov siab. Lawv kuj tseem ua tau zoo tshaj xoom -}} Lub tsev saib xyuas cov khoom siv kom yoog raws li cov kev xav tau ua haujlwm ntawm ntau cov ntawv txuas.
2. Lub hwj chim thiab cov qauv kev xa tawm: Cov qauv hauv tsev feem ntau yuav txais cov kev siv hluav taws xob kev daws teeb meem.Piv txwv li, XCMG XC956 Pro tus kheej- Cov planetary gearque converter, thiab tshuab hluav taws xob siab ib qho kev sib tw siab sib phim.
Lub log Rims siv plaub - planetary iav qauv, txhim kho kom haum rau hnyav {1} Doses cov haujlwm. Nws tseem nruab nrab, nruab nrab, thiab hnyav {- dutings ua hauj lwm cov qauv, ua tiav hluav taws xob txuag kev cai thiab kev ua haujlwm.
3. Chassis thiab khiav iav: XCMG XC956 Pro tshwj xeeb ib sab pem hauv ntej thiab kev faib tawm loj heev qhib thiab txo cov kev txiav txim siab pin kev ntxhov siab.40 DEGREE QAUM ZIB LUB CAIJ NTUJ TOOLGLE Ua Haujlwm Ua Haujlwm Ua Haujlwm. Qee cov kab ntsig kab ntsig tau nruab nrog cov log tsheb sib xyaw ua haujlwm saib xyuas cov log tsheb loj los ntawm cov iav khiav ntawm qhov tiag tiag- lub sijhawm tshuaj xyuas.
4. Cab thiab cov tswv yim ntse: lub cab nta yog qhov sib txuas ntawm panoramic thiab tib neeg -} cenved tsim.XCMG XC956 Pro thiaj yuav tau txais lub tiaj nyom canoramic, ua ke nrog lub rooj poob siab {} - absor direction- decirectal contrology kauj. Kab Ntsig Qauv Txhawb cov tswv cuab hauv kev customators hauv kev customizing ntau dua 25 lub functions ntawm Programmable cov nqi ntawm cov chaw taws teeb tshiab thiab kev daws teeb meem.
Tsis tas li ntawd, cov twj paj nruas digital yog cov qauv, ua rau muaj kev saib xyuas cov txheej txheem ntawm cov xwm txheej, ua tiav kev tswj hwm ntawm kev ua haujlwm zoo.
