FIELD: transport.SUBSTANCE: proposed trolley has bearing structure features preferred elongation along translation and bearing hollow guide secured at its bottom and along said translation. Note here that gates comprise bearing structure including bearing base to be secured to ground and bearing element secured to said base, at least, one pair of support wheels fitted on bearing element to run in aforesaid guides to take up, in fact, the weight of gates. At least, one guide wheel fitted on bearing element to revolve in vertical axis in said guide to counteract gated deflection perpendicular to their translation. Note here that bearing structure comprises two stamped plates, each including beating wall and bottom wall extending continuously from bearing wall by means of, in fact, rectangular flexure. Note also that bearing walls are rigidly jointed together by fasteners to make bearing element. Note also that two bottom walls are directed in opposite directions to make bearing base on ground. Note also that every bearing wall of stamped plate has two first holes aligned with appropriate first holes on the other wall to make to seats of first pairs of bearing wheels. It has also second through holes aligned with that of the other wall to make second set for guide wheel for it to rest on second bearing revolving means.EFFECT: simple, cheap and reliable design.13 cl, 10 dwg |
