Extended speed range


Operating mode:

  • Allows quicker lift and lower with loads lower than nominal load
  • With loads less than 20% of capacity, the hoist can lift up with twice the rated speed
  • ESR is a variable-frequency drive control, where the allowed speed is calculated by the value of the load in the hook


  • The entire power of the rolling bridge can be used all the time
  • Heavy Loads - Rated Speed
  • Light loads - Speed up to 200% of rated speed
  • Maximized productivity - reduces the duration of a work cycle and waiting times.
  • Does not require the over-dimensioning of mechanical and electrical components.
  • Significant time savings if most of the loads being handled are below 20% of the nominal load
  • Particularly advantageous for high lifting heights
