Khoom qauv ntawm 800kg Mini Excavator

Nws feem ntau yog tsim los ntawm cov cuab yeej hluav taws xob, cov khoom siv sib kis, cov cuab yeej taug kev thiab cov cuab yeej ua haujlwm. Lub hauv paus ntsiab lus: Siv lub thoob txhawm rau khawb cov ntaub ntawv saum toj lossis hauv qab ntawm cov kabmob, thiab thauj lawv mus rau hauv tsheb thauj mus los lossis cov tshuab txav hauv av uas tsis thauj khoom mus rau qhov chaw khaws khoom. Lub tshuab mining nws tus kheej uas siv lub thoob los rub cov strips lossis cov khoom ntxhia los ntawm lub ntsej muag ua haujlwm thiab thauj mus rau qhov chaw pov tseg kom tshem tawm. Keeb kwm: Thawj phau ntawv excavator muaj keeb kwm ntawm ntau tshaj 130 xyoo. Nyob rau lub sijhawm no, nws tau dhau los ua kev txhim kho los ntawm cov tshuab hluav taws xob uas tau tsav los ntawm lub thoob teb excavators mus rau hluav taws xob-tsav thiab sab hauv combustion engine-driven rotary excavators, thiab tag nrho tsis siv neeg hydraulic excavators siv electromechanical thiab hydraulic integration technology. txheej txheem kev txhim kho ib ntus. Raws li kev siv tshuab hydraulic, muaj cov tshuab excavators nruab nrog hydraulic backhoes ntawm cov tsheb laij teb hauv xyoo 1940. Thaum ntxov thiab nruab nrab -1950s, rub tag nrho kev sib hloov hydraulic excavators thiab crawler-type tag nrho hydraulic excavators tau tsim. . Thawj qhov kev sim tsim ntawm hydraulic excavators siv hydraulic tshuab ntawm aircraft thiab tshuab cuab yeej. Lawv tsis muaj hydraulic Cheebtsam haum rau ntau yam kev ua haujlwm ntawm excavator. Kev tsim khoom zoo tsis ruaj khov txaus thiab cov khoom txhawb nqa tsis tiav. Txij li thaum xyoo 1960, hydraulic excavators tau nkag mus rau theem ntawm kev txhawb nqa thiab kev loj hlob zoo. Excavator manufacturers thiab ntau yam nyob rau hauv ntau lub teb chaws tau nce sai heev, thiab cov zis tau surged. Los ntawm 1968 mus rau 1970, cov zis ntawm hydraulic excavators accounted rau 83% ntawm tag nrho cov excavator tso zis, uas yog ze rau 100%.
