The SAMUS collimator cart is a support for shielding blocks and the vacuum assembly of the Tevatron beam tube as it passes through the D0 End Iron. It slides on linear bearings mounted in the SAMUS toroid as the End Iron moves in and out. There are two collimators designed for the D0 experiment, designated North and South, each identical except for the shimming of the tungsten center blocks, and thereby the relative position of the Tevatron tube. This report contains calculations of the stresses during installation as well as the installed configurations. To support the analysis of the installation case, loads were simulated on the cart held in a mock-up of the lifting fixture
