Linear Technology Technical route
S+R supplied four electric actuators rated at around 350 kN each, with robust mounting, weather protection and sensors for safe end-position monitoring of the bridge movement.
Real-world infrastructure project
Bridge drive: four electric actuators of around 350 kN each for two movable bridges
Two movable bridges are opened and closed by four electric actuators of around 350 kN each - weatherproof, controlled and serviceable over the long term.

Operational safety & weatherFocus
Initial situation
Why a catalogue-only answer would not have been enough.
Movable bridges combine high individual forces, continuous outdoor use and safety requirements. The drives have to guide reliably, detect end positions safely and remain serviceable over long periods - in any weather.
Result
The bridges can be moved in a controlled way; the drives are designed for outdoor duty, safe end-position monitoring and long-term serviceability.

Building blocks in the project
Proven principles, adapted to load case and interface.
The product ranges remain technical starting points. What matters is how spindle, motor, protection class, sensors, mounting and service access work together in the actual project.
Next step
Your project can often be assessed with a few technical details.
Helpful inputs include force, stroke, speed, installation space, environment, voltage, control, quantity and existing drawings or photos of the interface.
