<p>PURPOSE:To facilitate precision position-adjustment for installation of under- floor equipment by applying an air bag and holding the equipment movable. CONSTITUTION:A car 4 which travels on wheels 6 is equipped with a lifter 8 to control the height of a table 9. A rack 11, on which the under-floor equipment 3 is held, is provided over an air bag 14. The car 4 is moved under the bracket 2 of the under frame 1 of the rolling stock, and the table 9 is lifted by means of the lifter 3. When the air bag 14 is inflated by air, the equipment 3 becomes easily movable, facilitating precision adjustment of installation positioning.</p> |
