Heavy-duty lock drive with 22 electric actuators
For a large lock system, S+R supplied 22 heavy electric actuators that move loads in the range of around 1,000 kN together.

Concrete solutions show how S+R approaches projects.
These examples show industry, technical challenge, solution route and result.
Project examples
From load case to matching assembly.
The value lies in the technical translation: existing interface, environment, force, stroke, sensors, service and repeatability.
