The Strassmayr RWK FR crack-sealing machine is designed for easy preparation and dosage of special sealing compounds for the cracks, joints or road edges. The design of this unit allows easy assembly on any platform. The main tank walls are filled with thermal oil, allowing to work with sealing materials heated up to 180˚C. The horizontal mixer and heated grill located on the top of the boiler are ensuring constant delivery of the sealing compounds to the applicator lance without the risk of blocking the mixer operation while adding fresh blocks of material.
