Elinye lamalungelo obunikazi okuqala “lesaha leketango elingapheli” elihlanganisa uxhaxha lwezixhumanisi ezithwala amazinyo esaha lanikezwa uFrederick L. Magaw waseFlatlands, eNew York ngo-1883, ngokusobala ngenjongo yokukhiqiza amabhodi ngokwelula iketango phakathi kwezigubhu ezigobile.Ilungelo lobunikazi lakamuva elihlanganisa uhlaka lomhlahlandlela lanikezwa uSamuel J. Bens wase-San Francisco ngo-January 17, 1905, inhloso yakhe kuwukuwisa i-redwoods enkulu.I-chainsaw yokuqala ephathwayo yathuthukiswa futhi yanikezwa ilungelo lobunikazi ngo-1918 ngu-Millwright waseCanada u-James Shand.Ngemva kokuba evumele amalungelo akhe ukuba aphele ngo-1930, ukusungula kwakhe kwathuthukiswa inkampani eyaba inkampani yaseJalimane i-Festo ngo-1933. Le nkampani, manje esebenza njenge-Festool, ikhiqiza amathuluzi kagesi aphathwayo.Abanye ababambe iqhaza ababalulekile ku-chainsaw yesimanje nguJoseph Buford Cox no-Andreas Stihl;laba banelungelo lobunikazi futhi benza i-chainsaw kagesi ezosetshenziswa ezindaweni zokubhakha ngo-1926 kanye nesaha elisebenza ngophethiloli ngo-1929, futhi basungula inkampani ezozikhiqiza ngobuningi.Ngo-1927, u-Emil Lerp, umsunguli we-Dolmar, wakha isaha lokuqala emhlabeni elisebenza ngophethiloli futhi wawakhiqiza ngobuningi.

IMpi Yezwe II yaphazamisa ukuhlinzekwa kwamasaha aseJalimane eNyakatho Melika, ngakho kwavela abakhiqizi abasha, kuhlanganise ne-Industrial Engineering Ltd (IEL) ngo-1939, eyandulela i-Pioneer Saws Ltd kanye nengxenye ye-Outboard Marine Corporation, umkhiqizi omdala wamasaha eNyakatho. eMelika.

Ngo-1944, uClaude Poulan wayeqondise iziboshwa zaseJalimane ezisika i-pulpwood e-East Texas.U-Poulan wasebenzisa i-fender yamaloli endala futhi wayenza yaba ucezu olugobile olusetshenziselwa ukuqondisa iketango."I-bow guide" manje yavumela ukuthi i-chainsaw isetshenziswe ngu-opharetha oyedwa.

UMcCulloch eNyakatho Melika waqala ukukhiqiza ama-chainsaws ngo-1948. Amamodeli okuqala ayesinda, amadivaysi abantu ababili anemigoqo emide.Ngokuvamile, amasaha ayesinda kangangokuthi ayenamasondo afana namasaha.Ezinye izingubo zisebenzisa imigqa eshayelwa kusukela kuyunithi yamandla enamasondo ukushayela ibha yokusika.

Ngemva kweMpi Yezwe II, ukuthuthukiswa komklamo we-aluminium nokwakhiwa kwenjini kwenza amasaha alula kangangokuthi umuntu oyedwa wayengawathwala.Kwezinye izindawo, ama-chainsaw nama-skidder crews athathelwe indawo yi-feller buncher kanye ne-harveer.

Ama-chainsaws acishe athatha indawo yamasaha asetshenziswa abantu emahlathini.Zenziwe ngosayizi abaningi, kusukela kumasaha amancane kagesi ahloselwe ukusetshenziswa ekhaya nasengadini, kuya kumasaha amakhulu “agawula amapulangwe”.Amalungu amayunithi onjiniyela bezempi aqeqeshelwe ukusebenzisa amasaha, njengoba kunjalo nabasebenzi bokucima umlilo ukuze balwe nemililo yasehlathini futhi bavuthele umlilo wezakhiwo.

Izinhlobo ezintathu eziyinhloko zokulola ama-chainsaw zisetshenziswa: ifayela eliphathwa ngesandla, i-chainsaw kagesi, ne-bar-mounted.

Isaha likagesi lokuqala lasungulwa ngu-Stihl ngo-1926. Amasaha anentambo atholakala ukuze adayiselwe umphakathi kusukela ngeminyaka yawo-1960 kuya phambili, kodwa awazange abe yimpumelelo kwezohwebo njengohlobo oludala olusebenzisa igesi ngenxa yobubanzi obulinganiselwe, ukuncika ekubeni khona isokhethi kagesi, kanye nobungozi bezempilo nezokuphepha bokuthi i-blade iseduze nekhebula.

Esikhathini esiningi sasekuqaleni kwekhulunyaka lama-21 amasaha ahamba ngophethiloli ahlala ewuhlobo olujwayeleke kakhulu, kodwa abhekane nokuncintisana namasaha asetshenziswa ngamabhethri e-lithium angenantambo kusukela ngasekupheleni kwawo-2010 kuya phambili.Yize amasaha amaningi angenazintambo emancane futhi elungele ukusika uthango nokuhlinzwa kwezihlahla kuphela, u-Husqvarna no-Stihl baqala ukukhiqiza amasaha asayizi aphelele okusika izingodo ekuqaleni kwawo-2020.Ama-chainsaw asebenza ngebhethri kufanele agcine ebona ukwanda kwesabelo semakethe e-California ngenxa yemikhawulo yezwe ehlelelwe ukuthi iqale ukusebenza ngo-2024 ezintweni ezisebenza engadini ezisebenza ngegesi.
