Choyikamo chopanda boltchakhala chodziwika kwambiri m'zaka zaposachedwa chifukwa cha kusinthasintha kwake komanso kusavuta. Ma racks awa alandiridwa kwambiri m'mafakitale osiyanasiyana, kuphatikiza malo osungiramo zinthu, ogulitsa, ngakhalenso ntchito zogona. Kumvetsetsa nthawi yomwe idadziwika komanso chifukwa chake akupitiliza kutchuka kumatha kuwulula zabwino zomwe amapereka ndikufotokozera kufalikira kwawo. Magwero a ma racking opanda bawuti amatha kuyambira chapakati pa zaka za m'ma 1900, ndikuyambitsa zida zachitsulo zosinthika. Komabe, sizinali mpaka zaka za m'ma 1970 pamene kukwera kwa boltless kunayamba kugwiritsidwa ntchito kwambiri. Nthawi imeneyi yakhala ikupita patsogolo kwambiri pakupanga ndi kupanga makina opangira ma racking awa. Anapangidwa makamaka kuti athetsere malire a machitidwe opangira ma racking omwe amafunikira bolt ndi nati. Kupangidwa kwa mashelefu opanda boltless kunasintha makampani osungiramo katundu popereka njira ina yabwino komanso yosinthika.
Chimodzi mwa zifukwa zazikulu za kutchuka kwamashelufu opanda mabotolondikosavuta kukhazikitsa. Mosiyana ndi machitidwe ojambulira achikhalidwe, kukwera kwa boltless sikufuna zida zambiri kapena ukatswiri kuti asonkhanitse. Izi zimawapangitsa kukhala osavuta kwa ogwiritsa ntchito chifukwa amatha kukhazikitsidwa mwachangu ndikusinthidwa pazosowa zosungirako. Kupanda ma bolts ndi mtedza kumathetsanso chiopsezo cha ngozi chifukwa cha zotayira zotayirira, kuonetsetsa kuti njira yosungiramo yotetezeka komanso yodalirika.
Chinanso chomwe chikukulitsa kutchuka kwa ma racking opanda bolt ndiko kusinthasintha kwake. Chifukwa cha mapangidwe awo osinthika, mashelufuwa amatha kusinthidwa mosavuta kuti agwirizane ndi maonekedwe ndi makulidwe osiyanasiyana. Kusinthasintha kumeneku kumathandizira kugwiritsa ntchito bwino malo ndi scalability, kupanga ma racks opanda bolt oyenera ntchito zosiyanasiyana. Kuonjezera apo, kukwera kwa boltless kungathe kusokonezeka mosavuta ndi kukonzanso, kupatsa ogwiritsa ntchito mwayi wokonza dongosolo losungiramo zinthu monga momwe zosowa zimasinthira pakapita nthawi. Kusinthasintha uku kumapangitsa kuti ma racking opanda bolt akhale abwino pazokonda zamalonda komanso zogona.
Mwachidule, rack yopanda bolt yakhala yotchuka m'zaka zaposachedwa chifukwa cha kuphweka kwake, kusinthasintha, komanso kuphweka kwake. Akula kuchoka pamalingaliro osadziwika bwino kupita ku njira yosungiramo zinthu zodziwika bwino m'magawo osungiramo zinthu, ogulitsa ndi malo okhala. Kukula kwa ma racking opanda bolt mzaka za m'ma 1970 kudakhala gawo lofunika kwambiri pantchito yosungiramo zinthu, kupereka njira yabwino komanso yosinthika yosinthira machitidwe achikhalidwe. Ndi kufunikira kosinthika, njira zosungirako zosavuta kugwiritsa ntchito zomwe zikupitilira kukula, sizosadabwitsa kuti ma racking opanda bolt akukhala otchuka kwambiri ndipo akuyembekezeka kukhalabe chisankho chodziwika kwa zaka zikubwerazi.
