Integration of Diesel Motor within a Shuttle Car for the Mining Industry

MJ Engineering was tasked with integrating a diesel motor and electric generator in place of a battery pack or cable reel of a mining shuttle car. The customer, who provided a specific set of specifications, needed the diesel motor packaged within the shuttle car’s existing 55 ¾” x 68″ x 32 ¾” reel compartment. We also faced the added challenge of having to ensure that the new motor/generator system was easy to maintain in the harsh and unforgiving mine environment.

To accomplish these tasks, MJ Engineering used a number of different design and engineering processes. We first designed a proper motor/generator mounting frame. Using the natural frequency of the motor/generator we were able to determine which frequencies to avoid so we could design the most stable mounting frame. Then we focused on designing a drive system linking the motor to the generator. Utilizing our outstanding design team we were able to eliminate the need for a battery pack or cable reel within the mining shuttle car. After all this work was completed, MJ Engineering was able to supply the client with 3D CAD models and CAD drawings of the final design.
