By adding a Spanco TrackBoss™ Enclosed Track Tractor Drive to your crane system, you can motorize the pushing, pulling, and positioning of overhead loads:

  • Convert your push-pull manual bridge cranes to power-driven cranes.
  • Convert your monorail systems from manual to power.
  • Convert your push-type manual trolley hoists to motor-driven trolleys.

TrackBoss Tractor Drives are particularly useful for workstation cranes when the operator can’t stand next to the load because of obstacles, such as large production machinery or worktables. 

Our tractor drives can also speed up cycle times when moving heavier loads, larger loads, or awkwardly shaped loads. Additional applications include workstation cranes with longer spans, or wherever manual movement of loads is challenging.
