We install stage lifts in the stage floor, which can be used to elevate any element from under stage. Many times are used in orchestra spectacles.

It is based on spiral columns that allow elements to rise to the stage very quickly and safely with no need of unused space in the bottom and without drilling holes in the ground because the body can be stored in a column at a maximum space of 60 cm.
