The spent fuel casks in the shield cover can be transported and hoisted into the designated shaft according to the orders with the help of cask handling overhead crane. If necessary, the spent fuel casks are hoisted out of the shafts according to the orders, and handled into the shielded transfer casks through the transfer hoisting hole or transported to the loading position and returned the remaining fuel element to the reactor core by the method of suction.

High temperature gas cooled reactor adopts advanced CAE simulation analysis and reliability design, by means of redundant design, to guarantee the safety and reliability of complex mechanical structure.
It adopts independent detection and positioning system and adopts high-precision matching mode in mechanical structure, which guarantee the crane positioning accuracy within ±3mm.
Through bottom plate alignment device and special lifting device, the complex transfer process of the spent fuel casks is realized.
Through the advanced control system and the application of intelligentized control program, it can realize dynamic display and image automatic switching. It also has the functions of remote operation monitoring and automatic operation.
