  • Sway Reduction with EXPERTOPERATOR™

    PaR Systems' EXPERTOPERATOR™ allows for the manipulation of payloads in a swing-free manner. EXPERTOPERATOR™ permits both novice and expert crane operators to reduce payload swing by 85-95%.

    Expert crane operators skillfully time crane maneuvers in order to quickly eliminate load swing. EXPERTOPERATOR™ is a hardware module that intercepts pendant commands - converts them into expert commands - and then issues the modified commands to motor drives. Cable sway is eliminated, permitting all operators to perform like experts.




  • Safety - Load sway prevention reduces risk of equipment damage and personnel injury.
  • Productivity - Hundreds of operator studies demonstrate that cycle time improves by 10 to 40%.
  • Precision - Accurate load placement is simple because operators focus on positioning rather than swing correction.
  • Service Life - Maintenance costs and downtime are reduced by decreasing mechanical and structural stress.
  • Personnel - Novice operators perform as well as experienced counter parts, reducing the need for extensive training.


  • Sway Elimination over entire hoist range with complicated rigging configurations.
  • Sensor less technology does not require encoders, zone sensors, or other length measurement devices and no operator input.
  • Seamless integration into existing hardware platform.
  • Simple - No operator input.
  • Compatible with existing VFDs, radio and tethered pendants with continuous or multi-step functionality.
