Swivel Joint TKSJ-200
Swivel Joint TKSJ-200
A device for guaranteed safe, remote operation of nuclear power
Swivel joints are used as shown below in related operations at facilities such as nuclear power research institutes, nuclear fuel offices, and radiation treatment research and development facilities (pharmaceutical companies).
They are especially used as handling equipment for the hot cells installed in nuclear fuel reprocessing plants, waste analysis facilities, and radiation treatment research and development facilities.
For handling equipment, generally a master-slave type for handling large-scale radioactive substances and a tong manipulator for handling small-scale radioactive substances are installed in parallel or individually.
The ball sockets we use are compatible with the models most commonly used in industries dealing with radioactive materials within Japan, and we handle all components in the overall system: ball sockets (corresponding to various types of radiation seal specifications: corresponding to the shield wall thickness), tong manipulators, boots (with airtight mechanisms), boots mounting cell rings, boots mounting and removal jigs etc., and we also handle equipment and consumables.

Swivel joint
The Swivel joint is a part that supports the operation of the tong manipulator.
The spherical ball joint mechanism is capable of 3-dimensional range of operation with an elevation angle of ± 45 °.
Also, depending upon the thickness of the radiation-resistant wall, a ball socket specification can also be used.
The standard of radiation protection material is lead, but other materials can be used depending upon your needs.
However, it is necessary to consider the γ ray transmittance of the material, as shown below.
Since radiation energy intensity varies depending on the radio isotope to be handled, shielding specifications need to be taken into consideration.
