Winding Drum Drive

Winding Drum Elevator

Time tested, technology improved.

Based on early elevator lift assemblies, the Symmetry Winding Drum Elevator utilizes heavy duty aircraft cables attached to a rotating drum. The drum is attached to a variable speed motor to move the elevator car and ensure ‘smooth’ stops and starts.

With our advanced electronics package and in-house design engineered software and controller, the Symmetry Winding Drum Elevator is the smoothest and quietest drum drive on the market for home elevators.
