Abstract

A locking device for handling/lifting equipment for use in nuclear reactors uses differential heating by electrc heaters to deflect the operating arms of the locking device from the 'in' and 'out' positions and vice versa. Used for lifting or locking device in a nuclear reactor and provides a simple robust method of operating a locking device suitable for use in hot atmospheres under radioactive conditions and in contact with non lubricating fluids.
