Izici Eziyinhloko:
Isakhiwo:

Ama-Girder Amabili: Umklamo wama-girder aphindwe kabili uvumela ububanzi obubanzi kanye nomthamo omkhulu wokuphakamisa uma kuqhathaniswa nama-crane e-girder eyodwa.
Uhlelo Lwenqola: Isiphakamisi sihamba eduze kwamabhande, okuvumela ukuphakamisa okuqondile kanye nokunyakaza okuvundlile.
Umthamo Wokuphakamisa:

Ngokuvamile, ama-crane amabili athwala imithwalo enzima, ngokuvamile adlula amandla ama-crane athwala imithwalo eyodwa.
