Continuous Improvement, Safety and ‘Thinking outside the box’

As a big fan of continuous improvement I'm always in the market for examples of great innovation, so how about this one?

The operators of this machine feed the bricks into the machine via gravity, there are no moving parts, and the path is laid as the machine moves, it’s amazing!

Is this is an example of a great idea providing safety and getting operational improvement as a by-product or operational improvements bringing safety as a by-product?  Or is it a case of inherent safety through good design?  Or is it all three?

Whatever the driver it is still fantastic!
