Already in the 1980s, Putzmeister started developing mobile, computer-aided handling systems. The first system (HFH) was ready in 1986 and was characterised by highly flexible and computer-aided operation. This was followed by the development of the SKYWASH Robots, which were controlled by sensors. These new technologies and devices were the precondition for the new generation of technology at Putzmeister, which led to the EBC master control and the development of Ergonic® modules, which
could be guided by a joystick.
