Curves can be with tapered rollers or cylindrical.
The drive is transmitted with chain loops and the gear motor is typically in a central position.
The driven tapered rollers permit the design of flat curves with reduced dimensions, guaranteeing the regular load movement. For the straight section it is recommended to maintain the same “EL” width of the curves, compatible with the standard length of taper rollers.
The tapered rollers with belt transmission are introduced in the section “Rollers for belt driven conveyors”.
