    Abstract: An escalator handrail drive arrangement includes a drive belt (26) mounted within a drive housing (35). Pressure rollers (30) are mounted in pairs and pivotally attached to the drive housing. The pressure rollers bias a handrail (22) against the drive belt. The pressure roller arrangements are mounted at each axial end. A spring (44) biases the pressure roller arrangements against the handrail, with the spring being centered along the axial length of the pressure rollers. This spring is preferably mounted within the drive housing such that no additional space is required outwardly of the drive and roller arrangement to accommodate the spring.
