Handling device allowing the vertical transfer of loads between two levels. The loading of the totes in the device is synchronously made, when soft carriages take place. The unloading is made when those carriages wrap themselves up. The generated relative movement allows also the loads moving on a receipt conveyor. The loadings and unloadings can be made either on the same side (C version) or on two opposite sides (Z version). This device is also available in stainless steel version for clean environments like food industries.
