Question #473
Where are anti-drop supports installed?
Gdzie montowane są łapy oporowe?
a
on the crane access platform
na podeście suwnicy
b
on the bottom flange of the end carriage
do pasa dolnego czołownicy
Correct answer
c
at the ends of the runway
na końcach torowiska
d
on the starting resistors
na opornikach/rezystorach rozruchowych
Why?
Anti-drop supports (łapy oporowe) attach to the bottom flange of the end carriage (pas dolny czołownicy), above the rail and near the travel wheels. This lets them support the structure after wheel or axle failure. Runway ends carry end stops (odboje), not anti-drop supports.
