ABSTRACT:
An engaging lever lock for rotor turning gear in a steam turbine includes a selectable lock that is disposed to hold the lever at its engaged position and control circuitry for activating the selectable lock. With a first embodiment, the selectable lock includes an electromagnet. On the other hand, with a second embodiment, the selectable lock includes a plunger-pin arrangement that is activated by a solenoid to extend into a hole formed in the lever, and is biased toward a retracted position away from the hole by a spring which is disposed around the pin between the plunger and the solenoid.
