Anti-Sway Crane Controls

Crane Motion Controls

Anti-sway technology enables crane operators to skillfully maneuver cranes safely and efficiently. PAR Systems’ anti-sway technology, EXPERTOPERATOR™, is a hardware module that converts pendent commands into expert commands issued to motor drives. This permits all crane operators to perform like experts. Hook sway is eliminated, efficiency and safety are increased.

Increase Productivity & Cycle Time by up to 40%

EXPERTOPERATOR™ anti-sway crane control system allows for the movement of payloads in a swing-free manner- permitting crane operators to reduce payload swing by 85-95%. Using this technology operator studies have proven increased safety of personnel and equipment, cycle time improvements up to 40%, more accurate load placement, reduced crane maintenance and extended crane life.

How it works.

EXPERTOPERATOR™ works by intercepting operator commands, then modifying those commands into what a seasoned expert would generate. The modified commands are then issued to the crane. This allows novice operators to drive as proficiently as their experienced counterparts, moving loads safely in a swing-free, efficient manner.


  • Increase Productivity: Hundreds of operator studies demonstrate that cycle time improves by 10% to 40%.


  • Compatibility: Seamlessly works with existing VFDs, radio and tethered pendants with continuous or multi-step functionality.


  • Seamless Transition: This retrofit solution integrates into your existing hardware platform with typical installation time of 1 day.


  • Increased Accuracy: Accurate load placement is simple because operators focus on positioning rather than swing correction.


  • Maintenance Reduction: EXPERTOPERATOR is the only anti-sway technology that does not require sensors of any kind, even with complicated rigging configurations.


  • Increased Safety: Load sway prevention reduces risk of equipment damage and personal injury.


  • Minimal Training: Novice operators perform as well as their experienced counterparts, reducing the need for extensive training.

Maximize crane lifting operations with our complete platform of crane motion controls.

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.

​​SAFEMOVE Collision Prevention
SAFEMOVE™ enhances an operator’s ability to make complex moves safely and avoid collisions between payloads and surrounding equipment. Virtual safety zones can be easily configured throughout the workspace, and quickly enabled and disabled. SAFEMOVE can limit crane motion in multiple regions throughout the workspace and can be used in conjunction with EXPERTOPERATOR technology.
​​CRANEVISION Side Load and Snag Detection
CRANEVISION™ is a combination of advanced motion control and machine vision technologies. Vision-based crane manipulation helps the operator avoid side pull and snag conditions for safer crane operations. With CRANEVISION™ the crane is made safer and smarter. Dangerous conditions, like off-center hoists and snags, can be detected and appropriate action taken to avoid accidents.
AUTOMOVE Automatic Positioning
AUTOMOVE™ allows for automatic and precise payload positioning utilizing standard crane controls. Automatic motion can be initiated and monitored by an operator. AUTOMOVE builds on the foundation of PAR’s proprietary anti-sway technology, which permits cranes to move without payload swing.

Our expert crane controls greatly reduce sway to make even a novice look like an EXPERTOPERATOR.
