Scorpion HD is the solution of U.Emme for the forestry sector dedicated to frontal coupling on large Skid-Steer Loaders, Wheel Loaders, Backhoe Loaders and Telehandlers. Two models of different working sizes equipped by two layers of anti-wear steel on the edges include sides on which 2 integrated slides are designed for running on the ground. The rotation movement is transmitted from a piston engine to a helicoidal rotor via a 5.5 cm high performance HTD pre-drilled belt, protected by a bolted plate. The internal supports of the rotor are equipped with a «labyrinthe» to protect the swivel bearings from impurities. A valve block equipped by a priority valve for oil flow regulation, anti- shock and anti-cavitation protects the engine even from the most hard uses.
