This animation shows how to mount and dismount the VAX Module 2 during the maintenance.
The robot is to double actuate the internal mechanism in order to reach and seize the bellow. In the next step, a chain clamp has to be open to untighten the connection. Then, the chain clamp is pivoted back. Now, when the bellows is untightened, it can be compressed. In the last step, the Module has to be disconnected from the services. The procedure is the same as for Module 1, only the size of connections differs. Firstly, a chain clamp is open to untighten the connection. Later, a dedicated mechanism inside Module 2 compresses the vacuum components to liberate the connection.
The Module 2 is ready for removal and transport. (Video: CERN)
