Suwnica trawersowa służy do:
a
lifting hazardous loads
podnoszenia ładunków niebezpiecznych
b
lifting loads using an electromagnet
podnoszenia ładunków za pomocą elektromagnesu
c
lifting ladles containing molten metal
podnoszenia kadzi z ciekłym metalem
d
lifting long loads (e.g. reinforcing bars, pipes)
podnoszenia długich ładunków (np. prętów zbrojeniowych, rur)
Correct answer
Why?
A lifting beam (trawersa) supports a long load at several spaced points, helping it stay balanced and reducing bending. This makes it suitable for pipes and bars. Using a lifting beam does not necessarily mean using an electromagnet.
