Lelei o seevae ala

Tulaga ese meatotino, maualuga malosi, maualalo laei ma loimata, teʻi-faamaoniga
E masani lava, e i ai ni pu faʻafesoʻotaʻi luga o se ala seevae ma le isi lua faʻamama lua i le ogatotonu, O le faʻamama pu mafai ona kilia ese le ipu otometi. Lua tuaoi papatusi o loʻo faaputuputuina vaega. Ina ia aloese mai maʻa fasi pipisi i le va ma mafua ai faʻaleagaina, ala seevae ma lapisi ala seevae tafatolu-foliga mafai ona faʻaaogaina pe a o se excavator ma bulldozer tamoʻe luga eleele susu, aua o le tafatolu -foliga mafai ona oomiina le eleele vaivai ma faʻateleina le lagolagoina gafatia.

I le taimi nei, o le masani bulldozer ala ipu mafai ona vaevaeina vaevaeina i lua ituaiga: mafolafola ipu ma nifo ituaiga ma V-foliga le-ala nifo ituaiga ma koluse vaega (taufusi ala seevae. O auala ia e lua o loʻo faʻaaogaina i eleele masani ma eleele vaofanua, ae a galulue ni bulldozers i le tundra, latou te feagai ma tulaga masani e lua o le eleele: o le faigata, faʻasolo malie i le maualalo o le tau ma le palapala, palapala susu i le maualuga o le vevela. I lenei siosiomaga, e ui lava o le masani ai vaʻalele-nifo laupapa laupapa mafai ona galue luga o le permafrost, pe a galue i le eleele, o le tele o eleele o le a pipiʻi i ai, ma mafua ai le paʻu o le pipiʻi o le ala. Ona o le faigata o le faʻamamaina, e manaʻomia le maimau le tele o le aufaigaluega e faʻamama aʻo leʻi faʻaauauina le faʻagaioiga, lea e matua afaina ai le gaosiga lelei. le talafeagai mo permafrost tulaga ona o le le lava o ala auala, e mafua ai i le ogaoga le lava o uʻu.

O le aoga faʻafanua bulldozer crawler ipu atiina ae e la matou kamupani faʻatoʻilaloina vaivaiga o le taimi nei crawler ipu ma ei ai le lelei o lua ituaiga o masani crawler ipu. E maua ai se ituaiga o mea-tau tolotolo laupapa polokalame mo bulldozer ma isi mea totolo savali savali e galue i le 'aisa eleele siʻosiʻomaga, lea e mafai ona sili ona faʻaleleia ai le faʻagaioiga lelei o bulldozer ma isi mea totolo savali savali. O le mafuaʻaga o le aoga faʻataʻitaʻiga o le iloa i le auala lea, e aofia ai le V-foliga faʻasolosolo ipu lona koluse-vaega tino ua saunia ma crawler nifo i le pito i lalo o le crawler ipu. O le koluse vaega o totolo nifo o trapezoidal. V-foliga koluse-vaega vaega ua faʻapipiʻi palapala le faigofie, faigofie e faʻamama, faʻamalieina tele lelei, i le laueleele susu o le tolotolo mafai nifo ei ai le lelei o permafrost, puipuia slippage, o lea fofo le masani vaega e le mafai ona fetuʻunaʻi i le permafrost siosiomaga tulaga o lua ituaiga o masani faʻafitauli eleele, faʻaleleia le faʻagaioiga malosi o le taʻavale taʻavale.

O le uiga o le bulldozer ala ipu o le vaega nifo o le ala nifo ma trapezoidal. Fausaga uʻamea lafo fausaga ma faʻamalosia lotoifale, crawler ipu ua saunia ma se faʻapipiʻi pu.
