Abstract
This research aimed to study the design of the overhead crane of a small fishing boat maintenance factory according to the building and functional requirements of the project based on the ASME B30.2-2005 Standard. The results of the study showed that the design of the runway with steel structure BS: 5950: 2000 grade s460 provided vertical and horizontal deflection values of 4.96 and 16.62 respectively that did not exceed the allowed deflection. It is strong enough for use in construction when the stresses on the beam bridge were analysed by the finite element program compared with the strength of the reinforced steel providing a safety value of 1.83.
Highlights
15 meters and the crane must be able to carry a load of 20 tons and the design must comply with the requirements
The vertical and horizontal actual deflection was calculated from (1) and (2), respectively, which was acceptable only if the result was no more than the permitted deflection as calculated from equation (3)
The design of the beam cross-section used for deflection analysis is as follows: The figure is shown in Fig. 3: Table 2
Summary
15 meters and the crane must be able to carry a load of 20 tons and the design must comply with the requirements. The design calculation is shown in Table 1., requirements. The main structure of the crane is iron with BS: 5950: 2000 grade S460 and has high strength per weight unit.
