Transfer panel

This is a panel that uses transfers balls to move material or objects around machines, places, etc. When using multiples units they can formed different configurations and can pivot to a certain degree. It has at the bottom pull latches and pivot pins to provide attachment between units. It's is not ideal ( my drawings skills are limited) but I would like to see somebody to improve upon the idea and help others that operate machines (like me ) to have a better system for handling heavy materials and objects
