  • Patent number: 10843905
    Abstract: A hoist support system includes a rail assembly having a rail along which a motor assembly is translatable by actuation of a motor of the motor assembly. The motor assembly is adapted to support a hoist and is communicatively coupled to a control system. The control system is adapted to measure motion of a slung load coupled to the hoist and to determine whether and to what extent the slung load is swinging or otherwise unstable. In response to such measurements, the control system transmits control signals to the motor of the motor assembly to change the position of the motor assembly along the rail and attenuate the motion of the slung load.
