Various embodiments include apparatuses for performing maintenance on a gas turbine bearing area, along with related methods. One apparatus can include: a set of rails sized to couple with the gas turbine and rest coaxially with a bearing adjacent the gas turbine, the set of rails for supporting a portion of a housing of the bearing; a first platform spanning between the set of rails; a lifting device coupled to the first platform for engaging an inlet bellmouth of the gas turbine; and a second platform suspended from the set of rails sized to accommodate an operator.
