•  Both for mechanized towing and manual handling.
•  Six patented rubber wheels “Bertoli”, can be partitioned, with rhomboidal distribution:
  >    Two central fixed ø 300 x 75, with load-bearing function, with built-in hermetically grease-sealed hubs.
  >    Two (one on each head) ø 150 x 45, pivoting and twinned, with balancing function and with threadguards.
  >    Our particular system of fork swivelling on vertical hub, allows to distribute the load on two ball bearings, and guarantees a great handling and long life. The rounded form of the rubber ring makes better all these characteristics.
  >    The rubber rings are belted with multiple layers of special rubberized canvas, to guarantee non-deformability and long life.
  >    Natural rubber ring studied and made to obtain more elasticity, long life, minimum traction effort.
  >    Imperforabile
  >    Acid, oil, solvent proof
  >    Trace proof
  >    Thermal resistance from + 180°C a – 45°C.
