Electronic Anti-Sway System

Our economical and lightweight electronic anti-sway system is superior to any of the mechanical or hydraulic anti-sway systems available.

Our economical and lightweight electronic anti-sway system is superior to any of the mechanical or hydraulic anti-sway systems available.
The sensor-less electronic anti-sway system works in all weather conditions with no maintenance required.

Advantage of the sensor-less electronic anti-sway system:
Compared to the mechanical system Compared to the electric system with sensor
  • Lighter weight
  • No need for the hydraulic mechanical structure and piping work for hydraulic cylinder type
  • No need for the motor and mechanical structure for sheave open/close type
  • No need for maintenance of hydraulic system and mechanical structure
  • No need for an expensive sensor
  • No need for imaging processing equipment and special computer
  • Available for all weather conditions
  • No need for sensor maintenance
