Patent AT-E40068-T1: [Translated] SUPPORT DEVICE FOR ROBOT WITH PORTAL CARRIAGE MOVABLE ON RAILS.

The invention relates to a robot carrier structure constituted by a portal wagon (10) movable on rails (12, 13) and supported at its flanks by two carriages (20, 20 min ) each comprising two wheels (21, 22) longitudinally coupled by motion transmission means (25, 28, 30; 26, 29, 31) actuated in synchronism by an electric motor (27). The two electric motors (27) of the two carriages (20, 20 min ) further are so connected as to constitute an electric axis. n<??>Each wheel (21, 22) has a structure adapted to ensure a high adherence to the rail (12, 13), particularly due to the provision of a pair of rings (45, 46) of elastomeric material engaging the rolling surface (47) of the rail (12, 13).
