Kumayambiriro kwa 1980s China molanada adadzutsa mtundu wa khomo, kuwomba kwambala ndi mitundu ina yokhazikika kuchokera kunja. Kugawika portal kwagwiritsidwanso ntchito kwambiri pantchito zambiri, ndipo zakwaniritsa zotsatira zabwino. Chifukwa cha zovuta zabwino za kuwonongeka kwa portal, scafting iyi sinalimbikitsidwe ndipo imagwiritsidwa ntchito. Mafakitale angapo achipata adamangidwa ku China, ndipo zinthu zambiri zimakonzedwa malinga ndi mapulani ochokera kwa ogulitsa akunja. Kandapusa kwambiri ndi malo omwe amagwiritsidwa ntchito kwambiri mu mtundu watsopano wa scafting, koma amangogwiritsidwa ntchito kumadera ena ndi ma projekiti.
Kuyambira mu 1990s, mabizinesi ena apakhomo adaperekanso matekinoloje akunja ndipo adapanga kulongosola mitundu yatsopano, monga boroto scaffold, crabfold scaffold, nsanja yodutsa, ndi mitundu yosiyanasiyana ya mafelemu. Podzafika chaka cha 2013, panali akatswiri opanga zoposa 100, makamaka ku Wuxi, Guangzhou, Qingdao ndi malo ena. Mwaukadaulo, makampani osindikizira China ali kale ndi kuthekera kokonzanso ndikupanga zatsopano zatsopano. Komabe, msika wapabanja sunapangitse, ndipo makampani omanga alibe chidziwitso cha kuwulutsa kwatsopano.
Ndi kutuluka kwa njira zambiri zamakono ku China, mtundu wachangu-Steener Scael Scaffold Scaffold Scaffold Scaffold Scaffold Scal walephera kukwaniritsa zosowa za ntchito yomanga. Ndi ntchito yofunika kwambiri kukulitsa ndikulimbikitsa kugwiritsa ntchito kuwulutsa kwatsopano. Kuchita kwatsimikizira kuti kugwiritsa ntchito kulembera kwatsopano sikuti ndi kotetezeka pomanga, komanso kusala kwa msonkhano ndi kusamva. Kuchita bwino kwa msonkhano komanso kusonkhana kwachulukirachulukira kawiri. Mitundu yosiyanasiyana yomanga igwiritsire ntchito makina osiyanasiyana pazolinga zosiyanasiyana. Ambiri mwa mafelemu a Bridge amagwiritsa ntchito scaffold ndi mbale, ndipo ena amagwiritsa ntchito portal portal. Zambiri mwa kapangidwe kake kake kake kake kamene kamagwiritsa ntchito molimbika.
