PURPOSE: A table lift for detecting a mineral sample box on a high place is provided so that after approaching to a shelf, on which a mineral sample box is placed, regardless of the height of the shelf, operations are performed using a worktable, a chair and a shelf, which are installed on a table lift. CONSTITUTION: A table lift comprises a bottom frame(10), a worktable(20), a link member(30), a cylinder(60) and a lever(70). A plurality of moving members(110) are formed on the bottom or the side of the bottom frame and a foldable chair(80) and a table(90) are installed on the top of the bottom frame. The worktable is horizontally located on the top of the bottom frame. The link member is installed between the bottom frame and the worktable in order to raise the worktable. The cylinder is extended by the working fluid, which is supplied from a hydraulic pump(71) to lift the link member. The lever operates the hydraulic pump to supply the working fluid to the cylinder. |
