Abstract
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.

A lift efficiency improvement mechanism for use with a service wedge configured to be removably installed in an access slot of a turbine casing, the lift efficiency improvement mechanism comprising:
- 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 being configured to urge the service wedge to move relative to the access slot responsive to corresponding operator control movement.
A lift efficiency improvement mechanism for use with a service wedge configured to be removably installed in an access slot of a turbine casing, the lift efficiency improvement mechanism comprising:
- a connector element, which is connectable with the turbine casing proximate to the access slot;
- and
- a force multiplication device, which is supportably coupled to the connector element and movably coupled to the service wedge,
- the connector element and the force multiplication device being manually transportable, and
- the force multiplication device being configured to urge the service wedge to move relative to the access slot responsive to corresponding operator control movement.
A method of improving lift efficiency of a service wedge configured to be removably installed in an access slot of a turbine casing, the method comprising:
- disposing a connector element in connection with the turbine casing proximate to the access slot;
- manually transporting a lift efficiency improvement device to the connector element;
- supportably coupling the lift efficiency improvement device to the connector element;
- movably coupling the lift efficiency improvement device to the service wedge;
- and
- employing the lift efficiency improvement device to urge the service wedge to move relative to the access slot.
