How Does a Screw Drive System Work?
In simple terms:
- The motor spins a long threaded rod.
- The carriage grips the threads.
- As the rod rotates, the carriage travels.
- The attached door arm moves the garage door.
Why Screw Drive Systems Are Popular
- Fewer moving parts
- Smooth operation
- Lower maintenance than chain systems
- Strong lifting capability
However, the carriage pull assembly experiences wear over time.
What Are the Signs of a Failed Carriage Pull?
