Displacement Closed-Loop Synchronous Winch Unit

The displacement closed-loop synchronous winch unit, developed and manufactured by the SuGong team, can precisely display the lifting height of each winch on the control system’s touchscreen. Users can also intuitively grasp the relative height differences between the lifts of each winch.

On the touchscreen, users can select either to simultaneously raise and lower all winches in a coordinated manner, or to independently control the lifting and lowering of any single winch. The touchscreen displays the lifting and lowering speeds of each winch in the form of bar graphs and numerical values.

When all winches are linked and move simultaneously, the control system defaults to using the position height of one winch as the reference height. All other winches then use this reference height as their baseline and follow it in a closed-loop, synchronized manner.

On the touchscreen, users can set an allowable relative height error. When the actual height error exceeds this allowed range, an alarm prompt will be issued. Users can also set an unallowable relative height error on the touchscreen; when the actual height error surpasses this unallowable range, the system will trigger a shutdown protection.

On the control system’s touchscreen, the dynamic load tension of each hoist is displayed in the form of bar graphs and numerical values.

On the control system’s touchscreen, the average theoretical weight of each lifting point of the lifted workpiece is displayed in the form of a horizontal line and numerical values.

Users can set the maximum and minimum allowable load forces on the touchscreen, and the system will issue an alarm notification once the load exceeds this range.

Users can also set the maximum allowable tensile force and the minimum allowable tensile force on the touch screen, and the system will initiate a shutdown protection if the actual tensile force exceeds this range.
