1) Easy for installation : the machinery is designed for "DIY" (do it yourself) type. It is not necessary to dispatch engineers for installation works. Kung-Yu will provide Installation Manual and Operation Manual. 2) Easy for maintenance :No complicated electronic control panel. The local engineers/operators can do the job well. 3) Mobil style : the machine set can be easily removed from place to place. The transportation cost of concrete products are expensive. In stead of one big machine, the client can have some small l ones and put them in different location or even at the construction site. 4) Very Reasonable prices.
