Automatic handling control appts. used in hostile environment - uses light beams to transmit control signals to gantry crane

摘要

Containers, for example of radioactive material are carried on trucks to a position (p) where they are automatically lifted individually by a grapple on a telescopic jack depending from a trolley (11) on a mobile gantry (10). The grapple trolley and crane are programmed for automatically picking up containers, transferring them to and stacking them in the stacking area (4). Control signals and feedback of completed movements for sequencing subsequent movements are achieved by light/laser beams and mirrors.
