I understand the impetus behind developing this product, but find the approach patronizing. The quality of poorly built haitian structures is directly tied to the cost of building materials and lack of a building code. Anyone who can afford to use such a machine can surely afford to hire a structural engineer and offer rudimentary training to laborers.
"Code" is a scam. We either know how to build with quality and safety in mind or we don't. "Code" is language used for municipalities to "charge" people/owners for their use of their own property and be "paid" for doing very little. You either "labor" or you do not "labor".
Yeah, nice idea but not realistic. Hydraulic motor and honda engine?? What happens when the hydraulic couplings get filled with crud? More expense. Plentiful and cheap manpower should be doing the work of the engine - why not just a shaft with several hand-cranks, employ four guys to work the shaft - nothing to fail, gives people jobs, the guys can take turns loading the machine and turing the shaft, same team moves the machine around etc. Make it affordable for a small company of goodness sake, and fixable.
The problem is, as the video pointed out, the shovel method does NOT mix the concrete properly. It never has. I deployed to Haiti and witnessed first hand the consequences of decades of poor concrete construction in every city, Port au Prince, Jacmel, Les Cayes, and Jeremie to name a few. The mix must be kept at a steady rate and maintained for at least 15 minutes. 2 cubic yards can weight up to 4,000 lbs and there's no way a human team is going to be able to sustain or crank such weight for 15 straight minutes. Do you want 120,000 fatalities or safe homes because you believe that an extra 10 men should be attempting to mix 2 tonnes of concrete - and still can't do it properly. So please, do not criticize this design given its benefits. The hurricane that hit the country last year, fuel was widely available and if the hydraulic coupling are washed and kept clean (with the plugs that are provided), they will provide years of service. Labour is still extensively used as shown in the video. So you really do not know what you're talking about.
This new video is getting great reviews. I just met with a group that is building homes in Haiti, and they are impressed.
I am poor, can you place one in my back yard. Next to the Rolls is fine

I wonder if you can hand crank this?
Can you please send me a quote.
great
