A lift efficiency improvement mechanism is provided for use with a service wedge configured to be removably installed in an access slot of a turbine casing. The lift efficiency improvement mechanism includes a connector element, which is connectable with the turbine casing proximate to the access slot and a manually transportable lift efficiency improvement device, which is supportably coupled to the connector element and movably coupled to the service wedge. The lift efficiency improvement device is configured to urge the service wedge to move relative to the access slot responsive to corresponding operator control movement.
