Spiralift technology
The Spiralift is the basic component of some of the best world-renowned platform lifts such as orchestra, stage and piano lifts.
This technology uses two bands of intertwining stainless steel to form a strong and stable column.
- The Spiralift requires relative low-power electric motor drives thanks to its very high mechanical efficiency.
- Spiralift units can be configured easily in modular designs to suit any platform geometry and building architecture.
- Multiple units can be linked to the same drive train and fully synchronized.
Main features
