The ONA 40 is the precise answer to one of the most widely used gear units in the Orona portfolio: the O140. This drive unit was particularly common in machine-room-less systems – compactly installed in the shaft head, directly above the elevator cabin. A proven solution that, in many cases, is now technically outdated.
With the ONA 40, existing Orona systems can be modernized in a targeted and compliant manner – without compromising on quality, installation, or safety. A true upgrade for a widely used platform.
Suitable for elevator systems with O140 gear units from Orona:
- Modernization projects without a machine room
- Systems with limited space in the shaft head
- Operators looking for an independent alternative to the original manufacturer
- Elevators with requirements for energy-efficient and quiet drive technology
