Ukugawula iinkuni zeChainsaw

Elinye lamalungelo awodwa omenzi wechiza lokuqala "lokusarha yetsheyini engapheliyo" equka ikhonkco lekhonkco elithwele amazinyo esarha lanikwa uFrederick L. Magaw waseFlatlands, eNew York ngo-1883, ngokucacileyo ngenjongo yokuvelisa iibhodi ngokolula ikhonkco phakathi kwamagubu asele egobile.Ilungelo elilodwa lomenzi wechiza kamva elibandakanya isakhelo sesikhokelo sanikezelwa kuSamuel J. Bens waseSan Francisco ngomhla we-17 kaJanuwari, 1905, injongo yakhe ikukuwa i-redwoods enkulu.I-chainsaw yokuqala ephathwayo yaphuhliswa kwaye yanikwa ilungelo elilodwa lomenzi ngo-1918 ngumbhali wokugaya waseCanada uJames Shand.Emva kokuba evumele amalungelo akhe ukuba aphelelwe ngowe-1930, uyilo lwakhe lwaphuhliswa ngakumbi yinkampani yaseJamani iFesto ngowe-1933. Le nkampani, ngoku esebenza njengeFestool, ivelisa izixhobo zombane eziphathwayo.Abanye abaxhasi ababalulekileyo kwi-chainsaw yanamhlanje nguJoseph Buford Cox kunye no-Andreas Stihl;le yamva inelungelo elilodwa lomenzi wechiza kwaye iphuhlise i-chainsaw yombane ukuze isetyenziswe kwiziza ze-bucking ngo-1926 kunye ne-chainsaw esebenza ngepetroli ngo-1929, kwaye yaseka inkampani ukuba ivelise ngobuninzi.Ngowe-1927, uEmil Lerp, umseki weDolmar, wavelisa isarha yokuqala yehlabathi esebenza ngepetroli waza wayivelisa ngobuninzi bazo.

IMfazwe Yehlabathi II yaphazamisa ukunikezelwa kweesarha zaseJamani kuMntla Melika, ngoko ke abavelisi abatsha bavela, kuquka i-Industrial Engineering Ltd (IEL) ngo-1939, umanduleli wePioneer Saws Ltd kunye nenxalenye ye-Outboard Marine Corporation, umenzi omdala we-chainsaws eMntla. eMelika.

Ngowe-1944, uClaude Poulan wayesongamela amabanjwa aseJamani esika ipulpwood eMpuma Texas.U-Poulan wasebenzisa i-fender endala yelori kwaye wayibumba yaba sisiqwenga esigobileyo esisetyenziselwa ukukhokela ikhonkco."Isikhokelo somnsalo" ngoku sivumele i-chainsaw ukuba isetyenziswe ngumqhubi omnye.

UMcCulloch eNyakatho Melika waqala ukuvelisa i-chainsaws ngo-1948. Iimodeli zakuqala zazinzima, izixhobo zabantu ababini kunye nemivalo emide.Ngokufuthi, iisarha zamatyathanga zazinzima kangangokuba zazinamavili afana neesarha.Ezinye iimpahla ezisetyenziselwa imigca eqhutywayo ukusuka kwiyunithi yamandla enamavili ukuqhuba ibha yokusika.

Emva kweMfazwe Yehlabathi II, ukuphuculwa koyilo lwealuminiyam kunye noyilo lwenjini kwenza ukuba iisarha zibe khaphukhaphu kangangokuba umntu omnye wayenokuzithwala.Kwezinye iindawo, i-chainsaw kunye ne-skidder crews ziye zatshintshwa yi-faller buncher kunye nokuvuna.

Iisarha ezityatyekwayo zithathe indawo yeesarha ezisetyenziswa ngabantu kumahlathi.Zenziwe ngobukhulu obuninzi, ukusuka kwiisarha ezincinci zombane ezenzelwe ukusetyenziswa kwekhaya kunye negadi, ukuya kwiisarha ezinkulu "zemithi".Amalungu amacandelo oononjineli bomkhosi aqeqeshelwa ukusebenzisa isarha yeesarha, njengoko kunjalo ngabacimi-mlilo ukuze balwe ukutsha kwehlathi nokuphefumla imililo yezakhiwo.

Iintlobo ezintathu eziphambili ze-chainsaw sharpeners zisetyenziswa: ifayile ephathwayo, i-chainsaw yombane, kunye ne-bar-mounted.

Isarha yokuqala yombane yaveliswa nguStihl ngo-1926. Iisarha ezizintambo zaye zafumaneka ukuze zithengiswe kuluntu ukusukela ngoo-1960 ukuya phambili, kodwa ezi azizange zibe nempumelelo yorhwebo njengohlobo oludala olunamandla erhasi ngenxa yoluhlu olulinganiselweyo, ukuxhomekeka kubukho bombane. isokethi yombane, kunye nempilo kunye nomngcipheko wokhuseleko wokuba kufutshane kweblade kwintambo.

Uninzi lwenkulungwane yamashumi amabini ananye (21st century) eziqhutywa ngepetroli zahlala zilolona hlobo luxhaphakileyo, kodwa baye bajongana nokhuphiswano lwesarha zelithium eziqhutywa ngebhetri ukusuka ekupheleni koo-2010 ukuya phambili.Nangona uninzi lwee-chainsaws ezingenazintambo zincinci kwaye zilungele kuphela ukucheba iheji kunye notyando lomthi, u-Husqvarna kunye noStihl baqala ukwenza iisaha ezipheleleyo zokusika izigodo ekuqaleni kweminyaka yoo-2020.Iisaha ezisebenza ngebhetri kufuneka ekugqibeleni zibone ukonyuka kwesabelo sentengiso eCalifornia ngenxa yezithintelo zikarhulumente ezicwangciselwe ukusebenza ngo-2024 kwizixhobo zokulima ezisebenza ngegesi.
