Steuerbare Einwirkungen auf Kranbahnen

Controlling the actions on crane gantries.

When analysing the actions on a crane gantry, there is some leeway on the crane side, but the actions that may be applied to an existing crane gantry are fixed unless constructional changes are made. In particular, when new cranes, often with higher safe working loads, are to be mounted on existing crane gantries, the loadbearing reserves should not be sought solely in the gantry, but instead primarily in the crane itself, or rather its parameters.
Changing the crane parameters and adapting the crane design, e.g. longer wheelbase, horizontal guide wheels, softer buffers, etc., are better for the crane gantry. The horizontal forces acting on the crane gantry constitute the principal effects, and significant savings are possible here. But the risks must also be addressed.
Advice and case studies plus damage and practical experience, including the mistakes that frequently occur in design and calculations, add up to a new approach to the design of crane gantries for overhead travelling and portal gantry cranes.
