Abstract
A system for supporting a shaft inside a turbine includes a support member having load and counterweight portions. A fulcrum is between the load and counterweight portions, and the load portion is configured to fit inside the turbine. Nests are connected to the support member between the load and counterweight portions, and the nests are configured to rigidly connect the shaft to the support member. A counterweight is connected to move along the support member only on the counterweight portion of the support member. A method for supporting a shaft inside a turbine includes inserting a support member inside the turbine and connecting the shaft to the support member. The method further includes connecting a crane to a fulcrum on the support member, lifting the support member and shaft with the crane, and moving a counterweight on the support member to change a horizontal angle of the support member.
