A weightlifting block and associated methods of use are provided. The weightlifting block includes rotatable platforms mounted to interior surfaces of sidewalls of the weightlifting block. Wheels are attached to the bottom surface of the platforms. An activation lever is rotatably connected to the platforms and is configured to lift the platforms from an active position to an inactive position, wherein the wheels extend past a bottom edge of the sidewalls to allow for the weightlifting block to be rolled to a desired location. The activation lever may then be disengaged to retract the wheels on the platform back into the weightlifting block.

Weightlifting equipment and methods

Systems and methods are provided for a diagnostic system for a machine with a combustion engine and a variable geometry turbocharger that includes a vane position sensor. The diagnostic system includes a controller configured to calculate a learned span value of the turbocharger based on the output of the vane position sensor during a diagnostic procedure and a reference vane position sensor value. A plurality of learned span values are calculated each during a different one of a plurality of diagnostic procedures performed over a period of time and a first regression analysis to predict an expected learned span value at a defined future time using the calculated learned span value and the plurality of stored learned span values. An alert message is generated when the expected learned span value is indicative of a potential future fault of the turbocharger.
