Spider Cart Transporter

Project Summary

Safran currently uses and sells a large transportation cart to move jet engines around preparation areas and into the test cell of an engine center. The current transportation cart was designed in the 1980s and still functions properly today, but a modernization is desired. The new cart design needs to have an electric drive system, it needs to be more maneuverable, it needs to be created with easy to access off the shelf components, and it needs to have the same engine to cart interface as the original design. Finally, this cart will be globally distributed and used outside which means the cart must be designed to withstand a variety of harsh weather conditions.

Design Goal

Our goal for this design is to redesign the SPIDER transporter cart to be more modern. The cart needs to be self-propelled, electronically controlled, more maneuverable, and have safety features to protect operators and the surrounding environment. Our phase of the project focused on the design of the cart frame, drive motor system, control system, and battery system.
