Abstract
A system includes multiple lifting devices, where each lifting device includes a drum to draw in or let out a line, and a motor and transmission coupled to the drum to apply a torque thereto. A grouping module groups the lifting devices for synchronized operation in lifting a shared load. A load distribution management module monitors an amount of weight carried by each of the grouped lifting devices and provides feedback to a user to enable more optimal distribution of the shared load amongst the grouped lifting devices.
