On a newly delivered STS crane to one of our clients, some “strange” vibrations in the trolley were causing issues with operating the crane.
After a root cause analysis performed by STARKON in cooperation with FEDEM, the issue was found in the eigenfrequency of the trolley steel structure. The solution would be for the operator cabin to change this eigenfrequency.
STARKON’s team changed the steel structure of the trolley by adding 3 tons of steel reinforcements. The result was as expected: the vibrations are gone.
