  • Publication number: 20170334414
    Abstract: A system includes a sensor and a controller. The sensor is configured to detect sliding of a wheel of a vehicle. The controller is configured to communicate with the sensor and a traction motor operatively connected to the wheel such that the traction motor selectively applies forces in at least one direction to the wheel during operation. The controller is further configured to direct the traction motor to apply a motoring slide reducing force to the wheel when the sensor detects sliding of the wheel resulting from a frictional braking force.

  • Publication number: 20170334415
    Abstract: A system includes a plurality of wheels, a braking system, and one or more sensors. The plurality of wheels includes a guardian wheel and at least one non-guardian wheel and is disposed on a wheeled vehicle. The braking system is operatively connected to the guardian and non-guardian wheels and applies a first braking force to the at least one non-guardian wheel and a second braking force to the guardian wheel. The second braking force increases a slide risk of the guardian wheel beyond a slide risk of the at least one non-guardian wheel. One or more sensors disposed within the wheeled vehicle detect sliding of the guardian wheel allowing a corrective action to be taken to prevent sliding of the at least one non-guardian wheel.

  • Patent number: 9821417
    Abstract: The present disclosure is directed to systems and methods for removing or installing a pitch bearing of a wind turbine. The method includes installing a first pulley block at an up-tower location of the wind turbine and configuring a second pulley block with the pitch bearing. A pulley cable is routed from a ground location over the first pulley block to the second pulley block such that the second pulley block is configured to slide along the pulley cable. The method also includes rotating the pitch bearing to a tilted position. Thus, the method further includes lowering or lifting the pitch bearing in the tilted position so as to prevent the pitch bearing from colliding with the tower.

  • Patent number: 9822670
    Abstract: A power generation system may include: a first gas turbine system including a first turbine component, a first integral compressor and a first combustor to which air from the first integral compressor and fuel are supplied. The first integral compressor has a flow capacity greater than an intake capacity of the first combustor and/or the first turbine component, creating an excess air flow. A second gas turbine system may include similar components to the first except but without excess capacity in its compressor. A turbo-expander may be operatively coupled to the second gas turbine system. Control valves may control flow of the excess air flow from the first gas turbine system to at least one of the second gas turbine system and the turbo-expander, and flow of a discharge of the turbo-expander to an inlet of at least one of the first integral compressor and the second compressor.
