I-crane ye-tower crane inezincazelo ezilandelayo:
Ubukhulu bobude obungasekelwe - amafidi angu-265 (amamitha angu-80) I-crane ingaba nobude obungaphezu kwamafidi angu-265 uma iboshelwe esakhiweni njengoba isakhiwo sikhuphuka eduze kwe-crane.
Ukufinyelela okuphezulu - amamitha angama-230 (amamitha angama-70)
Amandla okuphakamisa aphezulu - amathani ayi-19.8 (amathani angu-18), amathani angama-300 (i-metric tonne = tonne)
I-Counterweights - amathani angama-20 (16.3 metric tons)
Umthwalo omkhulu ongawuphakamisa u-crane ungamathani angu-18 we-metric (39,690 pounds), kodwa i-crane ayikwazi ukuphakamisa isisindo esingaka uma umthwalo ubekwe ekupheleni kwejib.Lapho umthwalo usondela ku-mast, isisindo esiningi i-crane ingasiphakamisa ngokuphepha.Isilinganiso samathani angama-300 sikutshela ubudlelwano.Isibonelo, uma u-opharetha ebeka umthwalo ngamamitha angu-30 (amafidi angu-100) ukusuka ku-masti, i-crane ingaphakamisa umkhawulo wamathani angu-10.1.
I-crane isebenzisa ukushintshwa komkhawulo okubili ukwenza isiqiniseko sokuthi u-opharetha akalayishi kakhulu i-crane:
I-switch load enkulu iqapha ukudonsa kwekhebula futhi iqinisekisa ukuthi umthwalo awudluli amathani ayi-18.
Iswishi yesikhathi sokulayisha yenza isiqiniseko sokuthi u-opharetha akeqeli isilinganiso semitha yethani le-crane njengoba umthwalo uphuma ku-jib.Ukuhlanganiswa kwekhanda lekati kuyunithi yokubulala ingakala inani lokuwa ku-jib futhi izwe lapho kwenzeka isimo sokugcwala kakhulu.
Manje, kungaba inkinga enkulu uma enye yalezi zinto iwela endaweni yomsebenzi.Ake sithole ukuthi yini egcina lezi zakhiwo ezinkulu zimile.
