Abstract

A method of tensioning a conveyor element of a conveyor. The method includes generating, with a proximity sensor, an output signal indicative of the conveyor element being under-tensioned, receiving the output signal from the proximity sensor, and activating a solenoid-controlled valve to an open state in response to receiving the output signal from the proximity sensor. The method also includes driving, with a pump, a piston of a cylinder while the solenoid-controlled valve is in the open state, pushing, with the cylinder, a take-up bar including a second portion of a ratcheting mechanism to engage with a first portion of the ratcheting mechanism of a locking plate, and imparting, via the locking plate, a locking force on the take-up bar. The method further includes overcoming the locking force and moving the shaft of the conveyor away from a centerline of the conveyor with the take-up bar when the locking force is overcome.
