To deal with the poor operational and low reliability existing in the tradition lifting sling

a self-leveling lifting sling has been developed. It can automatically regulate the movement tendency of the main lifting point based on the current pose of suspended cargo

to achieve leveling suspended cargo; Meanwhile

it also can automatically calculate the barycenter of suspended cargo to adjust the final postion of the main lifting point

thus reach the suspended cargo leveling. Eventually

the design of lifting sling control system is based on these two above control strategies.
