500i Series Trolley

The Trolley is the drive mechanism for every 500i Series system. Each trolley contains four skewed Drive Wheels that ride on the Drive Tube.

As the Drive Tube rotates, the trolley is propelled through the system.

Each trolley also contains 4 Load Wheels that ride inside the load rail.

These wheels are part of the supporting mechanism for the trolley/carrier assembly.

There are also 4 Guide Wheels, which insure the trolley stays square on the load rails while in motion.
