Claims

[Scope of utility model registration request]

In a crane that moves on two running rails having curved sections arranged side by side along a quay, the distance between the wheels running on the inner rail of the curved section is smaller than the distance between the wheels running on the outer rail. A traveling device for a crane, characterized in that:
