Typically you see a feeder and dispenser system at the back of a trailer not at the front? 

What happens here

This video features a Belmont HDT-12 trailer, specifically highlighting its unique design where a conveyor belt moves material to the front rather than the traditional rear. A representative explains the advantages of this front-feeding mechanism, such as improved weight distribution and the ability to work with a dedicated lift gate for machines. This is a product demonstration, not a DIY project.
