Wheel-swivel

Most often, lifting wheel sorters are used in combination with two wide belt conveyors: the first one ends at the pick-up point, and the second one starts immediately after the pick-up point. In the gap between the conveyors there are rollers, the width of which is equal to the width of the conveyor. Between the rollers there are wheels having a drive and turned transverse to the direction of movement of the conveyor or at an angle to it; the wheels are located below the surface of the conveyor belt.
When the box reaches the gap between the conveyor belts, one of two things happens: the transverse wheels remain stationary, and the box continues to move forward – along the rollers to the next belt conveyor or the transverse wheels first rise, dragging the box along with them, and then, rotating, remove it from conveyor.
