Ubu bwoko bwa scafold bugizwe ahanini nibintu nyamukuru, ikadiri yambukiranya, umusaraba wa diagonal, ikibaho cya scafold, base base, nibindi.

Port scafold nimwe murwego rukoreshwa cyane mubwubatsi. Kuberako ikadiri nyamukuru iri mumiterere y "umuryango", yitwa portal cyangwa portal scaffold, izwi kandi nka Eagle frame cyangwa gantry. Ubu bwoko bwa scafold bugizwe ahanini nibintu bikuru, ikadiri yambukiranya imipaka, ikariso ya diagonal, ikibaho cya scafold, base base ishobora guhindurwa, nibindi. Porte scafold nigikoresho cyubwubatsi cyakozwe bwa mbere na Amerika mumpera za 1950. Kuberako ifite ibyiza byo guterana no gusenya byoroshye, kugenda byoroshye, ubushobozi bwiza bwo gutwara, gukoresha umutekano kandi wizewe nibyiza byubukungu, byateye imbere byihuse. Kugeza mu myaka ya za 1960, Uburayi, Ubuyapani nibindi bihugu byagiye bikurikirana kandi biteza imbere ubu bwoko bwa scafold. Mu Burayi, Ubuyapani no mu bindi bihugu, ikoreshwa rya portaf scafold nini nini, rifite hafi 50% yubwoko bwose, kandi ibigo byinshi byumwuga bitanga imiyoboro ya sisitemu zitandukanye byashizweho mubihugu bitandukanye.

Kuva mu myaka ya za 70, Ubushinwa bwagiye bukoresha uburyo bwa portaf scafold kuva mu Buyapani, Amerika, Ubwongereza ndetse no mu bindi bihugu, bwakoreshejwe mu iyubakwa ry’amazu maremare kandi bugera ku musaruro mwiza. Ntishobora gukoreshwa gusa nk'imbere n'inyuma yo kubaka inyubako, ariko kandi nk'igisate cyo hasi, inkunga yo kumurika ibiti na mobile scafold. Ifite imirimo myinshi, nuko nayo yitwa scafold-imikorere myinshi.

Mu ntangiriro ya za 1980, bamwe mu gihugu n'ababikora batangiye kwigana portal scafold. Kugeza mu 1985, abakora 10 portal scaffold bashizweho bikurikiranye.

Ibi byagize ingaruka zikomeye mu kuzamura ubu buhanga bushya.

Mu myaka ya za 90, ubu bwoko bwa scafold ntabwo bwari bwarigeze butera imbere kandi ntabwo bwakoreshejwe cyane mubwubatsi. Inganda nyinshi za gantry scafold zarafunzwe cyangwa zihindurwamo umusaruro, kandi ibice bike gusa bifite ubuziranenge bwo gutunganya byakomeje gutanga umusaruro. Niyo mpamvu, birakenewe guteza imbere ubwoko bushya bwa portal tripod hamwe nuburyo bwububiko bwigihugu cyacu.
