  • Patent number: 10793366
    Abstract: A tensioning system for a conveyor element of a conveyor. The tensioning system including a hydraulic apparatus, a locking plate, and a take-up bar. The hydraulic apparatus includes a cylinder having an extendible piston. The take-up bar is coupled to the cylinder and coupled to a shaft of the conveyor. The take-up bar moves the shaft of the conveyor in a forward direction away from the centerline of the conveyor when overcoming a locking force from the locking plate.
    Type: Grant
    Filed: November 22, 2019
    Date of Patent: October 6, 2020
    Assignee: Joy Global Underground Mining LLC

  • Patent number: 9932177
    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.

  • Patent number: 9757730
    Abstract: A breaker pick retainer system for a breaker includes a holder that defines a pick aperture and a pin aperture, and a breaker pick received in the pick aperture of the holder and including a pin receiving feature aligned with the pin aperture. The breaker pick retainer system including a pin received within the pin aperture of the holder and seated in the pin receiving feature of the breaker pick for maintaining the breaker pick within the holder. The breaker pick retainer system further including a resilient plug received within the pin aperture for sealing the pin aperture. The plug inhibits removal of the pin from the pin aperture.
