Question #512
A crane girder is:
Dźwigar suwnicy to:
a
the maximum load mass the crane can lift
maksymalna masa ładunku, jaką może podnieść suwnica
b
a beam forming part of the crane's load-bearing structure
belka, będąca elementem ustroju nośnego suwnicy
Correct answer
c
a set of levers for controlling the hoisting mechanism of a gantry crane
zestaw dźwigni do sterowania mechanizmem podnoszenia w suwnicy bramowej
d
a support element of the runway foundation or track
element podporowy podtorza lub torowiska
Why?
A girder (dźwigar) is a load-bearing beam of the crane bridge. It is part of the moving crane, not a runway support. The maximum load mass that can be lifted is the lifting capacity (udźwig), not the girder.
