The entire weight may be considered as concentrated at this point. Horizontal deflection is measured for workstation bridge cranes and workstation jib booms. Other advantages to box girders is the ability to design the girder depth to improve hook height, and the lower weight of the box reduces the structural requirements of the runway design by lowering the crane loads on the runways and support columns. Design calculation for rail wheels and associated trolley track supporting structure ? The vertical and horizontal displacement can cause changes in the design of the crane and also impact the working of the device. Each wheel gets some fraction of weight when we use a crane to lift and move the load. 2. The gantry girder is subjected to bending in vertical plane as well as in horizontal plane along with twisting., the design calculations are simplified by providing a channel at the top flange of the girder, and neglecting the bottom flange for transverse load computations. At that time all the factors related to traffic are used under one term like equivalent single axle load. This video demonstrates the Tekla Tedds Crane gantry girder design calculation.

This means that certain types of loads will produce higher side loads on the crane than it is designed to take Sail Area of Load 2.5 X 8 = 20m² (Sail Area) The rail must be situated directly over the inner web of the box girder, so that transverse flexural stresses in the top flange plate are avoided, as shown in Figure 12e. Point loads occur when relatively high weights are concentrated on a small bearing area. If you try to pick something up with the end of the crane hook, the load is not centered and would be “point loaded”. The box girder crane is an overhead travelling crane that uses a box girder as the crane bridge. Abstract– Double bridge girder overhead cranes are used for heavy duty applications in the industry. The structure must be strong, stable, and cost-effective. Brake 1. Based on above discussion, design of girder is a complex task for the designer.
