1. Status of MobiDICK 4 Vinícius Barbosa Schettino 1

2. Introduction MobiDick is a testbench used to provide full certification of the super-drawers during maintenance periods The system is currently in it’s third version, and the goal is to have a fourth one ready to use for the long shutdown, in 2013 The motivation to this new version is that it should be smaller and lighter, while using new technologies. It will provide better movability and make the system more reliable 2
