A huge thank you to all of the generous sponsors who helped make these upgrades possible: One Firefly, MetalWorks, Bullseye, American Fasteners, and SolidWorks.
The top of the carts, weighing approximately 400lbs when fully loaded, had to be manually raised and lowered throughout the 2017 season. To conquer this obstacle the team decided to design and build a linear lift over the course of the 2017 offseason. The upgrade consists of four 50lbs gas springs and two 250lbs linear actuators. The linear actuators are wired into a switch which allows them to be driven up or down with the press of a button. The system is powered by an FRC 12-volt battery.
