Abstract (en)
[origin: EP0488475A1] A conveyance system (10) with suspended rail (11) comprises trolleys (12) with an upper drive wheel (13) and lower bucking rollers (15,16). The wheel and the rollers are supported rigidly so as not to have reciprocating translation movements. Each trolley (12) has a geometry such as to cause a rotation moment around the upper wheel (13) when the trolley negotiates sloped sections of rail so as to increase the force of contact of the driving wheel (13) on the rail. The rail (11) has a cross section of variable height along its extension to allow holding uniform the distance between the wheel and the rollers despite curves for changing altitude. <IMAGE>
