Chained Winding Drum Below – How Does It Work?
The Winding Drum drive is popular for home elevators. The motor/gearbox is typically located at the top of the rail system, but it can also be located on a lower level, between the rails. This allows easier access to the motor, and a reduction in required ceiling height on the upper landing.
The drums and motor and gearbox reside between the rails, typically at the lowest level. The hoisting cables are secured to the cab and travel over pulleys and down to the drums. As the drums wind the cables, the cab moves upward. As the drums spool out the cable, the cab moves downward
The winding drum systems do not require a machine room as the motor/gearbox is located inside the hoistway. This space savings is a benefit in home design. The winding drum units also run quieter than other home elevator drives.
