A load beam for an aerial vehicle comprises an elongate beam with a radial slot and a lug extending from the radial slot. A hook is pivotably connected to the lug. There is a first arm pivotably connected to the beam and a second arm pivotably connected to the beam. The first arm may be pivotably connected to a first mount and the second arm may be pivotably connected to a second mount. A pivot axis of the first arm relative to the elongate beam may be substantially parallel to a pivot axis of the first arm relative to the first mount. A pivot axis of the second arm relative to the elongate beam may substantially parallel to a pivot axis of the second arm relative to the second mount.
