The electric powered continuous STL could be a preferred selection in low-range to midrange torque applications when a continuous turning operation is required and/or when manual operating has limited possibilities.

Advantages:

- Easy engagement and disengagement even with residual forces present
- Turning function is indexed turning with fully manual control
- Controlling is done fully locally, with provision for instruments for status detection (interlock)
- Fully independent from external power sources
- Low maintenance overtime with increased personnel safety
