Conveyor Chains are made of from high tensile strength steel. They are used to handle variety of materials like fuel and grains. In case there is overflow of material at discharge end, built in overflow device throws it out and if it is beyond acceptable limit, the limit switch stops the motor. Moreover for any reason, if speed of motor varies beyond tolerance limit, the sensor probe at tail end immediately gives signal to zero speed switches and switch stops the motor thus assuring complete safe operation.
