Abstract

A system (40) for supporting a shaft (32) inside a turbine (16) includes a support member (42) having load and counterweight portions (48), (50). A fulcrum (52) is between the load and counterweight portions (48), (50), and the load portion (48) is configured to fit inside the turbine (16). Nests (44) are connected to the support member (42) between the load and counterweight portions (48), (50), and the nests (44) are configured to rigidly connect the shaft (32) to the support member (42). A counterweight (46) is connected to move along the support member (42) only on the counterweight portion (50) of the support member (42). A method for supporting a shaft (32) inside a turbine (16) includes inserting a support member (42) inside the turbine (16) and connecting the shaft (32) to the support member (42). The method further includes connecting a crane (54) to a fulcrum (52) on the support member (42), lifting the support member (42) and shaft (32) with the crane (54), and moving a counterweight (46) on the support member (42) to change a horizontal angle of the support member (42).
