The Henderson BlackBelt handles it all with ease. Rip-rap. Rubble. Gravel. Sand. Boulders. Asphalt. The BlackBelt has a 54" wide pure belt delivery system that is both tough and high temperature tolerant.
   The LSBT "Load Sense Belt Tensioning" drive system adjusts the belt tension, depending on carrying torque requirements and prevents belt slippage on the drive drum.  No chains to jam or break. A low center of gravity gives the BlackBelt unbelievable stability on and off the road. The more extreme the load the better the BlackBelt likes it!
  Available in one foot increments up to 52 feet long.  The floor is AR400 for extra support and extreme impact resistance.
