A belt tension-reducing device is provided, which includes a support member; a pliable central wheel assembly configured to engage a both downwardly and upwardly moving portions of the conveyor belt; first and second outboard roller assemblies positioned to engage the downwardly and upwardly moving portions, respectively. A second effective rolling radius of the pliable central wheel assembly at a contact point with the upwardly moving portion of the conveyor belt can be greater than a first effective rolling radius of the pliable central wheel assembly at a contact point with the downwardly moving portion of the conveyor belt to reduce stresses on the belt in a vertical shaft. The belt tension-reducing devices can be arranged in a stacked configuration within the vertical shaft.
