Akukwazi ukusho ukuthi abanikazi bokuphenya bangenasisekelo, ngoba kwezinye izimo banesibopho sokusetshenziswa. Isibonelo, uma kungumbuzo wokweba ukudoba, okubandakanya ukulungiswa okuthembekile kwenduku yesikhathi esithile eside ukuze kutholakale kahle ukuhlanza. Ngaphezu kwalokho, ngalolu khetho, izandla kufanele zihlale zikhululekile, njengoba nje kudingeke ukuba uphathe isikebhe. Yiqiniso, umnikazi wokuqala wokupenda ngezandla zakhe uqobo kungenzeka, kodwa ezweni lanamuhla, asetshenzisiwe, okungahlinzeka ngenduduzo enkulu.
Kuye ngendlela yokunamathiselwe, izinhlobo ezintathu zemikhiqizo zihlukile. Abaningi abanamacala okuphenya bahlelwa esikebheni ngenxa yemishini ekhethekile efana ne-clamps. Lezi zindlela zitholakala ikakhulukazi ezigumbini zokhuni, amaplastiki kanye ne-aluminium. Uma kwenzeka isikebhe esine-inflatable, ukuqinisa kungenziwa kuphela nge-transom. Futhi uthengise imikhiqizo ekhonjiwe nezikuluvu noma izikuluvu. Kulesi simo, kudingekile indawo ebanzi yokubanzi okwanele. Amamodeli, ahlanganisa ukulungiswa kweglue, asetshenziselwa izikebhe ezinamapulisi e-PVC.
Namuhla, iningi labakhiqizi likhiqiza abanikazi ngokupenda, okwenziwa ngezinto ezihlukahlukene. Ama-copolymers, i-steel, i-polypropylene ne-aluminium alloys yayisetshenziswa kakhulu. Uma ukudoba kwenziwa emanzini olwandle, khona-ke izinto eziphikisana nokubola zidingeka. Ngokuqondene nama-aluminium alloys, abakhethiwe kaningi ngalabo bantu abangabonakali okubaluleke kakhulu kuwo. Ngokomandla, izinto zanamuhla ezingezona zensimbi cishe azikho ngaphansi kohlobo lwazo zendabuko. Nakuba ezimweni ezikhonkolo lapho kudingeke khona ukuphikisana okukhulu, ukusetshenziswa kwezakhiwo zensimbi kusengcono.
Noma yibaphi abanikazi bokuphenya babhekana ngokuyinhloko ngokuthi kungenzeka ukuthi bashintshe i-angle edingekayo emthambekeni wenduku, kanye nokukwazi ukushintshanisa nge-axis ngokuqondile. I-slope iyakwazi ukuhluka ngezinga elingamashumi ayisishiyagalolunye, kodwa inqwaba yamamodeli ayisekeli lokhu kungenzeka. Ngenxa yendawo enkulu yesenzo, kuyokwazi ukuvumelanisa nanoma yiziphi izimo zomzimba othile wamanzi. Ngokuqondene nokujikeleza eceleni kwe-axis, ikuvumela ukuba uthathe izintambo zezinduku kude nezinhlangothi ngezindlela ezihlukile.
Abanikazi abafanelekayo bokuphenya, asetshenziselwa isikebhe, kufanele babonakale bejabule futhi babe nesethi yokulungisa. Kuyinto efiselekayo ukugwema amamodeli ase-static, ngoba angenza ukudoba kube yinto engokoqobo yangempela. Njengomthetho, imikhiqizo yenziwa ngokucabangela izidingo zezinhlobo ezithile zokudoba. Kukhona futhi umehluko, kuye ngokuthi uhlobo lwenduku ethintekayo. Noma kunjalo, iningi labanikazi bavumela ukusetshenziswa cishe noma yikuphi okukhethwa kukho. Kule ndaba, uma uthenga, udinga ukucacisa ukusebenza kokusebenza.
