The invention is characterised in that carriage comprises two rectangular plates attached back to back with intermediate washer means and with 45° bent edge portions, whereby a resilient spring action of the central portion of each plate will be allowed when one or several of the wheels in the wheel pairs in connection to each corner of the carriage will pass unevenness on the linear track or a build up layer on the same track, whereby the wheels in each pair of wheels will rotate around shafts being mutually adjusted and bear during a permanently resilient action on each track, respectively.</p> |
