Abstract: A conveyor includes an endless belt, a boot end supporting a portion of the endless belt, a support structure, and a bridge. The endless belt includes a first run and a second run, and the first run extends along a conveyor axis. The support structure includes an end spaced apart from the boot end, a plurality of frames, and a plurality of idler rolls. The frames are spaced apart from one another and aligned with one another in a direction parallel to the conveyor axis. The idler rolls support another portion of the endless belt. The bridge extends between the boot end and the end of the support structure. The bridge is movable in a direction parallel to the conveyor axis relative to at least one of the boot end and the support structure.

Abstract: In combination a loader unit and haul unit for use in a block caving mining operation. Each of the loader unit and the haul unit comprise a removable bucket, which can be used for loading ore. In use the bucket carrying a load of ore can be transferred from the loader unit to the haul unit so that the haul unit can transport the ore from a loading site to a crusher. The loader unit and haul unit have a respective longitudinal axis extending from the fore end to the aft thereof, and the bucket is elongate with a longitudinal axis. In use when the bucket is mounted to the loader unit the longitudinal axis of the bucket is disposed orthogonally to the longitudinal axis of the loader unit. When the bucket is transferred to the haul unit, the bucket is placed upright on the haul unit with the longitudinal axis of the bucket parallel to the longitudinal axis of the haul unit.

Abstract: A tensioning mechanism for a conveyor system includes a first end including a drive unit, an anchor structure, a continuous belt extending at least partially between the drive unit and the anchor structure, a first carriage, and a second carriage. The first carriage is coupled to the drive unit and supports a portion of the belt. The first carriage is supported for movement relative to the drive unit to adjust a tension in the belt, and the first carriage is movable between the drive unit and an intermediate position. The second carriage is releasably secured to the anchor structure and supports another portion of the belt. The second carriage is supported for movement relative to the anchor structure between a first position and a second position. A distance between the first end and the second carriage defining a take-up length, and movement of the second carriage changes the take-up length.

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.

Abstract: A conveyor for a mining system. The conveyor includes a sprocket, a chain, a drive mechanism, a hydraulic cylinder, and a controller. The chain is associated with the sprocket and has a top chain portion and a bottom chain portion. The drive mechanism is coupled to the sprocket and is operable to drive the sprocket. The controller includes a processing unit and a memory. The controller is configured to receive a first signal related to a characteristic of the drive mechanism, receive a second signal related to a reaction force of the sprocket, calculate a tension of the top chain portion based on the first signal and the second signal, and generate a control signal for controlling a position of the hydraulic cylinder based on the determined tension of the top chain portion.
