The industrial company WROPOL Engineering has been operating since 1985. Our specialty is the implementation of special designs of technological machines based on hydraulic drives. Since the company's inception, our main focus has been on hydraulic drives, actuators and power units. These components serve as compact drives for equipment and machines. We test the drives on BISON hydraulic presses that we manufacture, such as those for briquetting biomass, metal chips and sawdust.
