chair or basket?



I had seen this guy and his DIY creation several times before
it was not clear to me the purpose of this front mounted apparatus 

with him paused to take a call
I saw an opportunity to snap a photo and ask some questions

my Spanish is good enough to hear him change the topic from what ever to "el americano con camara"
there was some exchange
he was flattered by the notion of his photo being taken and my interest in his contraption

turns out it is for work!

I wonder what he carries and how well it works
