Question #667
The overload limiter on an overhead crane should disable:
Ogranicznik udźwigu w suwnicy powinien wyłączyć:
a
the hoisting mechanism in the upward direction
mechanizm podnoszenia w kierunku "góra"
Correct answer
b
the hoisting mechanism in the downward direction
mechanizm podnoszenia w kierunku "dół"
c
only the bridge travel mechanism
wyłącznie mechanizm jazdy mostem
d
all crane mechanisms
Wszystkie mechanizmy suwnicy
Why?
The overload limiter (ogranicznik udźwigu) prevents an excessively heavy load from being raised. Lowering must remain possible so the load can be set down safely and the overload removed. Disabling every mechanism would prevent this lowering as well.
