Whilst in discussion with other group members, improvements to the design of the feet of the crane were purposed. The original design, featured to the left of the image below, required the area of ground immediately beneath them to be level. It is highly unlikely that level ground could be located in an earthquake disaster zone and thus the feet were redesigned, as featured to the right of the image below, and were fitted with rounded rubber (or similar) stoppers at their base.
This new design allows the crane to be placed in a greater variety of locations and increases the ease at which the crane may be assembled, as the symmetry of the new feet mean that they do not require orientating. The image below shows a close up of the new design integrated into the crane structure.
Finally, below is the revised crane structure in its entirety. This design will require farther design alterations, and the next purposed change will be to replace the main solid square beam with an "I" beam. This will increase strength whilst decreasing overal weight. The altered design incorporating this change will be produced, along with any other recomended changes, once the stress analysis has been completed.
