Title: Innovations by Inventor Markus Schäfer
Introduction
Markus Schäfer is a notable inventor based in Asbach / Hussen, Germany. He has made significant contributions to the field of construction machinery, holding three patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is for a self-propelled construction machine and method for working ground pavements. This invention features a machine frame equipped with at least three travelling devices and a hydraulic drive system. The hydraulic drive system includes a controllable hydraulic motor with variable displacement volume and a hydraulic pump. Additionally, it incorporates a working device, such as a milling drum, designed for ground pavement operations. A detection device monitors fluctuations in the longitudinal speed of the construction machine, allowing a control unit to adjust the displacement volume of the hydraulic motor accordingly. This ensures that the natural frequency of the hydraulic drive system is modified, maintaining a constant drive speed.
Another patent by Schäfer focuses on a self-propelled construction machine, particularly a road milling machine, stabilizer, recycler, or surface miner. This machine features a work roller and edge protectors on both sides. The hydraulic system allows for the raising and lowering of these edge protectors using a single main directional control valve, enhancing the machine's operational efficiency.
