摘要

Device for lifting and orienting track grids comprises a threaded spindle (2), and a clamping plate for attaching to the base (14) of each rail (15) and having threaded bores (6, 7) penetrated by the threaded spindle. The symmetrical longitudinal axes (9, 10) of the threaded bores to a vertical (11) run toward the under side (14a) of the rail base at an angle (phi 1) which is identical to the sum of the +/- angle (alpha ) of the rail inclination and the lateral inclination (phi 2) of the track grid to a horizontal (17) when in the final lifting position the threaded spindle with its symmetrical longitudinal axis is perpendicular. Preferred Features: The clamping plates are made of high-grade steel or constructional steel (ST 37-ST54).
