A flange manipulating device for installing and removing flanges includes a bar that is flat. Each of a pair of first holes that is positioned through the bar is positioned proximate to a respective opposing end of the bar. A coupler is coupled to and centrally positioned on the bar. Each first hole is configured to selectively align with a respective second hole that is positioned in a flange. The first hole and the respective second hole are configured to insert hardware, such as a bolt to couple to a nut, to couple the bar to the flange. The coupler is configured to couple to a tool, such as a wrench, to position the tool to selectively applying torque to the bar. The bar is configured to transfer the torque from the tool to the flange to selectively install the flange on and remove the flange from a threaded pipe.

The improved sleever bar comprises a bar, a removable nut and a fixed nut. The fixed nut is permanently attached to the bar at a fixed position. The removable nut is attached to the bar such that the position of the removable nut is adjustable. In a first function of the improved sleever bar, the improved sleever bar aligns the first object with the second object such that the center axis of each of a first plurality of holes is aligned with the center axis of a hole selected from a second plurality of holes such that a nut and bolt selected from a plurality of nuts and bolts can be used to secure the first object to the second object. In a second function of the improved sleever bar, the improved sleever bar separates the first object from the second object.

A method and apparatus for aligning an input shaft of a wind turbine generator with an output shaft of a wind turbine are disclosed. Preferably, the method includes placing a push plate of a wind turbine alignment tool into pressing contact with a selected support flange of a wind turbine generator identified by a misalignment measurement device. With the push plate positioned, an indexing means of the wind turbine alignment tool is advanced along an adjustment link member of the wind turbine alignment tool to impart an alignment force onto the selected support flange to align the input shaft of the wind turbine generator with the output shaft of the wind turbine. The method preferably concludes by rechecking the alignment of the input shaft of the wind turbine generator with the output shaft of the wind turbine.

A flange alignment pin is disclosed. An example flange alignment pin includes a pin with a tapered centering shoulder, at least one wrench flat, and a pin shaft having a threaded portion. The example flange alignment pin also includes a pin nut with a tapered centering shoulder, at least one wrench flat, and a threaded portion configured such that the threaded portion of the pin nut is threaded onto the threaded portion of the pin shaft.

A gasket insertion cradle with a bottom frame portion configured to align a gasket between opposing flanges of a flange assembly and capable of being removed from the flange assembly by simply rotating the frame portion free once the gasket is within ring grooves of the opposing flanges. Gasket insertion devices may have a top portion hinged to the cradle and configured to secure a gasket between the top portion and the cradle during installation.

The invention relates to an expandable device adapted to forcibly separate spaced components having generally parallel opposed surfaces defining a cavity therebetween, the expandable device having a jaw assembly with a pair of opposing jaws and actuating mechanism for opening the jaws, the actuating mechanism including a separating member configured to be driven between the jaws so as to push apart the jaws such that the jaws are openable between a contracted configuration where the jaws are receivable in the cavity to an expanded configuration where the jaws are forced apart by the actuating mechanism such that the outwardly directed surfaces of the jaws are engageable with the opposed surfaces and exert oppositely directed forces thereon. The invention also relates to an apparatus configured to carry at least one the expandable device, and an assembly comprising two of the apparatus.
