4S-2000 Ltd., in cooperation with its French partner, continues the research and development of cutting machines for building industry. During the project, after a thorough analysis of the market, a few prototypes were created, which form the basis for the development of successful market products. Based on Scandinavian experience, the realization of a ball screw lifting device is in process in cooperation with a Hungarian partner to help loading trucks. The development is beyond the final prototype before series production; production can start in the next period. Our latest project is the research and development won in the tender of the National Office for Research, Development and Innovation 2019-1.1.1-Market RDI - "Support for Market-Driven Research and Development and Innovation Projects" under the name "Creation of a special volume-changing rotating machine". The object of the development is a special-shaped ball pump, which has many advantages in comparison with conventional pumps.
