A device has lift arms (42) with links (46, 46D) connected to the ends of a loadspreader (40) or the links (46, 46D) swivelly connected to the lift arms (42) and aligned to hook special containers (20D). The lift arms (42) are pivotally connected to a hub (44, 44B) to swing vertically. Each hub is mounted to rotate on a vertical support shaft (38) central between the ends of the loadspreader (40) or hooking and lifting links (46, 46D) for each end of a load. A hydraulic cylinder (48) connects each lift arm to its hub to lift and lower the arms (42) together to lift and lower the loadspreader (40) substantially level. The hubs (44, 44B) can be rotated relatively horizontally to move the loadspreader (40) sidewise parallel and/or turn it to align a load. A rotary crane (18) carries the lift linkage about a support pivot with parallel positioning control to translate the loadspreader over a circular area and with control to extend or retract the loadspreader sideways.
