Rails with high lateral strength, developed for cranes. The wide held base flange (B) ensures that the surface pressure exerted by the load on the ground is low. Since the rail height (H) is low, there is no risk of rail tipping due to connection weakness. Even in the case of high lateral loads, the cradle loads are low. Since the side surfaces of the cork are wide, it is the most suitable rail type for the operation of guide roller systems. Since its vertical strength is low, it is necessary to support the gold from the top. For this reason, it is placed on a steel beam or on a continuous (continuous) base. Its connection to the ground is provided by ties. It is definitely not boiled to the ground.
