Abstract: A locking device (100) is operable to lock a tool (150) in an opening. The locking device includes a base (104) positionable with respect to a lifting member (152) of the tool when a first end of the lifting member is positioned within the opening. The locking device also includes a lift (106) coupled to the base for movement relative to the base. The lift includes an interface portion (110) coupleable to the lifting member such that the lifting member is moveable with the interface portion in an extraction direction of the opening when the lift is moved from a first position to a second position relative to the base.

Abstract: An alignment apparatus for aligning inlet guide vanes in a turbine having a turbine axis includes a tool body, a positioning block secured to the tool body, and a plurality of alignment pieces secured to the tool body. The positioning block may be affixed to the tool body such that when the positioning block is engaged with a leading edge of one of the inlet guide vanes, at least a portion of the alignment pieces is parallel to the turbine axis. The alignment pieces may be manually displaceable from the OFF position to the ON position into engagement with the inlet guide vanes to align one or more of the inlet guide vanes.
