Question #635
Combining overhead crane motions means:
Kojarzenie ruchów suwnicy to:
a
attempting to activate hook raising and lowering simultaneously
próba jednoczesnego uruchomienia podnoszenia i opuszczania haka
b
the ability to stop a load from swinging
umiejętność wygaszenia rozkołysanego ładunku
c
a basic mistake made by novice overhead crane operators
podstawowy błąd początkujących operatorów suwnic
d
simultaneously activating the movement of two mechanisms
jednoczesne załączenie ruchu dwóch mechanizmów
Correct answer
Why?
Combining motions (kojarzenie ruchów) means operating two mechanisms simultaneously, such as bridge travel and trolley travel, where the instructions permit it. Raising and lowering the same hook are opposite directions of one mechanism, so they do not constitute combined motions.
