Abstract
The present invention is a linearly actuated rotating handrail system for escalators and moving walkways. The system includes a worm band or a handrail, having a first friction device on one side, a dragging device formed by a second friction device and coupled to the first friction device to drag the worm band in the displacement direction. The pressure device includes a first layer of kinematic support, formed by a crank, an articulated shaft, a driving connection rod, shafts and driven cranks. There is a second layer formed by traction rollers. The application of pressure to the worm band or handrail and its balanced distribution over the different pressure rollers is carried out by slides actuated by a distributor, tightened by an elastic system. The elastic system transmits the tension by a beam.
