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.
