Don Eloy Alfaro in 1920 started his oxcart factory in Sarchi, and on January 18, 1928, Don Juan Kümpeln  sold him much of the machinery that was at La Hacienda La Eve. The genius of Don Eloy allowed the installation of  an efficient hydraulic energy system that generates 12 horsepower, powered by a nearby river called Trojan, which sets in motion all the machinery required in the workshop. From its founding until now, Eloy Alfaro Factory is known for its excellence in ironwork necessary for the production of carts, especially for the branding of the wheels. You could say that it is a complete factory because here is the axis lathed, also lathed the wheele center mass, sand everything that makes the hardware. This is the only factory of carts in the country that has worked and keeps working with hydropower.
