I-E4004A- IUchungechunge LwesitayelaUmshini Wezinsika uklanyelwe ukusebenza ngempumelelo kwemisipha eminingi ye-pectoral ngenkathi kunciphisa ithonya langaphambili lemisipha ye-deltoid ngephethini yokunyakaza ewohlokayo. Esakhiweni somshini, izingalo zokunyakaza ezizimele zenza amandla asebenze kahle ngesikhathi senqubo yokuqeqesha, futhi ukwakheka kwazo kwesimo kuvumela abasebenzisi ukuthola uhla oluhle kakhulu lokunyakaza.

Isihlalo Esilungisekayo
●Iphedi yesihlalo elungisekayo ingabeka isikhundla sesifuba sabasebenzisi abahlukene ngokuya ngosayizi wabo ukuze kufezwe ukuzivocavoca okuphumelelayo.

I-Ergonomics Enhle
●Ama-elbow pad adlulisela amandla ngqo emisipheni ehlosiwe. Ukujikeleza kwangaphandle kwengalo kuncishisiwe ukuze kuncishiswe ukucindezeleka kwamalunga ehlombe.

Isiqondiso Esiwusizo
●Ibhodi lokufundisa elisendaweni efanelekile linikeza isiqondiso sesinyathelo ngesinyathelo mayelana nesimo somzimba, ukunyakaza kanye nemisipha esetshenziswayo.

Ngamakhono okucubungula ezimboni akhula ngokukhula, ekwakhiweni kwesitayela sesembozo esiseceleni, hlanganisaIfa Lamasiko Elingabonakali - Ukuluka, I-DHZwaqala umzamo wokuqala wokuhlanganisa izinto zendabukoIzinto zaseShayinangemikhiqizo,Uchungechunge Lwesitayelayazalwa ngalokhu. Vele, i-biomechanics efanayo kanye nekhwalithi yomkhiqizo ethembekile kusabalulekile. Izici zesitayela saseShayina nazo ziyimvelaphi yegama lochungechunge.
