Kev Ruaj Ntseg Qib Khawb Av: Hitachi EX1800 / EX1900 Track Sprocket Log Sib Dhos

1. Kev Taw Qhia: Lub hauv paus ntawm Ultra-Class Khawb av

Hauv kev siv cov tshuab khawb av loj, kev khawb pob zeb, thiab kev tsim kho vaj tse hnyav, Hitachi EX1800 thiab EX1900 series sawv cev rau qhov zoo tshaj plaws ntawm kev ua haujlwm hydraulic excavator. Nrog rau qhov hnyav ua haujlwm tshaj 180 metric tons thiab lub peev xwm thoob txog li 15 cubic meters, cov tshuab no ua haujlwm hauv cov xwm txheej tsis tu ncua - cov khoom siv hnyav, cov khoom siv abrasive, thiab kev hloov pauv tas mus li.

Lub Rooj Sib Tham Txog Kev Sib Tw Khiav Sprocket (tseem hu ua kev sib tw khiav saw sprocket) yog qhov tseem ceeb ntawm lub zog tsav tsheb uas hloov lub zog hydraulic mus rau hauv traction. Rau kev ua haujlwm hauv kev khawb av hauv Chile txoj siv tooj liab, South Africa lub chaw khawb av platinum, lossis Lavxias cov teb hlau, qhov kev ntseeg tau ntawm lub rooj sib txoos no ncaj qha txiav txim siab cov hom phiaj tsim khoom thiab tus nqi ib tuj.

Tsab xov xwm no muab kev tshuaj xyuas tob txog kev sib dhos sprocket OEM zoo uas tau txheeb xyuas los ntawm cov lej ntu.1028990,4451622, thiab4637264, tsim tawm raws li cov txheej txheem nruj ntawmCQC TRACK- ib qho kev tshwj xeeblub Hoobkas qhov chawthiabtus tsim khoomntawm cov khoom siv hauv qab ntawm EXC uas ua haujlwm hnyav.

2. Cov Lus Qhia Txog Kev Siv Tshuab & Kev Hloov Pauv

2.1 Kev Txheeb Xyuas Cheebtsam

Peb tus lej ntawm cov khoom sib xws rau cov kev hloov pauv ntawm lub rooj sib dhos sprocket siv thoob plaws Hitachi EX1800 thiab EX1900 platforms:

• 1028990: Feem ntau yog hais txog lub rooj sib dhos ua tiav ntawm lub log sprocket (hub + ring) rau cov kev teeb tsa tsav kawg tshwj xeeb.
• 4451622: Feem ntau cuam tshuam nrog lub nplhaib sprocket segmented lossis lub rooj sib dhos rau cov qauv EX1900 tom qab.
