Scaled Construction Equipment

The main objective of the project is to repair and improve the tower crane that was designed by the MET capstone group from last year [1]. After it was assembled and used over the summer, several issues were found. The secondary objective is to design and fabricate a scaled crawler crane that can be mounted onto a barge or crawler tracks attachment. The cranes will be used as an educational tool and must replicate the operations of a crane as realistically as possible.
