Conclusion

The actual crane design was good but the beams that were going to be used did not have standard dimensions. This made it difficult to get an accurate costing of the beams and would have meant a factory would not have been needed to manufacture the customised beam designs. The use of actuators for the sidebars would help the crossbar to move horizontally but not much tought was given as to how they were going to be fixed to the beams. Overall the basic design of the crane was good but there was not enogh time to think about the more detailed parts of the crane such as the pins and screws.
