ABSTRACT:
A conveyor system (10) with a suspended rail (11) on which run trolleys (12) having an upper drive wheel (13) and lower bucking rollers (15,16). The wheel and the rollers are rigidly fixed relative to one another. Each trolley (12) has a geometry such as to cause a rotation moment around the upper wheel (13) when the trolley traverses sloped sections of rail to increase the force of contact or traction of the driving wheel (13) on the rail. The rail (11) has a cross section of variable thickness along its length so that the distance between the wheel and the rollers is uniform on the curves between straight horizontal and sloping sections.
