The invention relates to a robot carrier structure constituted by a carriage (10) movable on rails (12, 13; 12 min , 13 min ) and supported on four wheels (20, 22; 21, 23) two of which (20, 22) are mounted on a driven shaft (25, 25 min ) and two (21, 23) are idler wheels.
<??>Each drive wheel (20, 22) has a structure adapted to ensure a high adherence to the rail, particularly due to the provision of a pair of rings (45, 46) of elastomeric material in engagement with the rolling surface (47) of the rail (12, 13). Engagement means (43, 44) movable laterally on the rail (12, 13) are provided to increase the adherence of the drive wheels (20, 22). |
