ABSTRACT:
A belt take-up for a conveyor is provided with an internal compression spring to adjustably bias the bearing support tube to control tension on the conveyor belt. A scale on the bearing tube can provide a readout of the tension. A load cell can be employed to control a circuit to stop the conveyor motor when extreme high or low tensions of the belt are sensed.
