Abstract: A handrail drive for a passenger conveyor includes a drive belt that does not emcompass either the main drive shaft or the handrail drive shaft. In a particular embodiment, the drive belt includes a plurality of outwardly extending teeth and is formed from a reinforced elastomeric material. The teeth are engaged with complementary toothed extensions on the main and handrail drive shafts. Two pairs of deflection rollers maintain contact between the drive belt and drive shafts and an adjustable spring maintains tension in the drive belt.
