Ama-cranes wesitolo esiphansi yimishini emincane yokuphatha impahla esetshenziselwa ukuphakamisa noma ukuhambisa izimpahla. Imvamisa, umthamo wokuphakamisa usukela ku-300kg kuya ku-500kg. Isici esiyinhloko sokuthi umthamo wayo wokulayisha unamandla, okusho ukuthi njengoba ingalo ye-telescopic inwebeka futhi iphakamise, umthamo womthwalo uyancipha. Lapho ingalo ye-telescopic isusiwe, umthamo womthwalo ungafinyelela cishe ngo-1200kg, okwenza kube lula ukuthola imisebenzi elula ehambayo, okuyiyo elondolozwa kanzima futhi elula. Njengoba ukuphakama kukhuphuka, umthamo womthwalo unganciphisa ku-800kg, 500kg, njll. Ngakho-ke, ama-cranes aphathekayo kagesi alungele ukusetshenziswa emihlanganweni yokucobelelana. Isisindo sezingxenye zezimoto asisinda kakhulu, kepha kunzima kubantu abazophakamisa ngesandla. Ngosizo lwe-crane encane, izingxenye ezisindayo ezinjengezinjini zingaphakanyiswa kalula.

Mayelana namamodeli wokukhiqiza wamanje, sinamamodeli ajwayelekile ayi-6, ahlukaniswe ngokuya ngokucushwa kwemishini ehlukene. Nge-Hydraulic Mobile Crane, amanani entengo aphakathi kwe-USD 5000 ne-USD 10000, ehlukahluka ngokuya ngomthwalo womthwalo odingwa yikhasimende kanye nokucushwa kwemishini. Ngokuphathelene nedizayini ephethe umthwalo, umthwalo omkhulu uvame ukuvame amathani ama-2, kepha yilapho ingalo ye-telescopic isesimweni esibuyisiwe. Ngakho-ke, uma udinga i-crane encane futhi elula ye-crane, ungabheka i-crane yethu yesitolo esincane.
