500 Series Trolley

The Trolley is the carrying mechanism for every 500 Series system. Each trolley contains four skewed Drive Wheels that ride on the Drive Tube. As the Drive Tube rotates, the trolley is propelled along the system. Each trolley also contains four Load Wheels that ride on the load rail. These wheels are part of the supporting mechanism for the trolley/carrier assembly. There are also four Guide Wheels, which insure the trolley stays square on the load rails while in motion.
