Ukuphakama okuphezulu kakhulu kwe-scaffolding ngaphandle kwe-outriggers (ukucushwa okuzimele) kunqunywa kakhulu yizidingo zokuzinza, kanye nemikhawulo ebalulekile etholakala ezindinganisweni zobunjiniyela kanye nemithethonqubo yokuphepha:
-
Umkhawulo Wesilinganiso Sobubanzi Besisekelo Kuya Kubude
Izicabha kumele zinamathele ku-Isilinganiso sobubanzi bokuphakama kuya kwesisekelo esingu-4:1Ngokwesibonelo:- Ububanzi besisekelo bungu-1.5m → Ukuphakama okuphezulu = 6m(19.7 ft)
- Ububanzi besisekelo bungu-2.4m → Ukuphakama okuphezulu = 9.6m(31.5 ft)
Lokhu kuvimbela ukugoba ngaphansi kwamandla omthwalo noma omoya.

Imingcele Eqondene Nezinto Ezibalulekile
- Izinhlelo zensimbi zohlaka lwe-H: Ngokuvamile kuvaliwe ku-9–12m (30–40 ft) uma usebenzisa i-diagonal bracing kanye nokuxhumeka kohlaka oluqinile.
- Izikulufo ze-aluminium: Umkhawulo ophansi we-~ 7.5m (24.6 ft) ngenxa yokuncipha kokuqina kwesakhiwo uma kuqhathaniswa nensimbi.

Izidingo Ezibalulekile Zokuphepha
Ukuphakama okungaphezu5mKudingeka wonke umuntu:- Izibalo zesakhiwo eziqinisekiswe ngunjiniyela
- Ukuhlolwa kokuqondanisa okuqondile okuqhubekayo (ukubekezelelana ≤1/200 kokuphakama)
- Ukukhishwa kwemithwalo enamandla (isb., ama-hoists) ngaphandle kokuzinza okwengeziwe.
⚠️ Ukuthobela imithetho yesifunda :
- INew Zealand iyalela isitifiketi sobunjiniyela bezakhiwo ezingaphezu kwamamitha ayi-5.
- Izindinganiso zase-UK (HSE) ziyakwenqabela izicafu ezizimele ezingenazo izinsimbi >9.6m kungakhathaliseki ububanzi besisekelo.
