 For the compact gearless ZETATOP series, Ziehl-Abegg is now offering a machine frame also for the 1:1 suspensions. The system is designed for use in existing machine rooms.
More and more gearless drive machines are being used when modernising elevator plants. That can be attributed especially to the technical advantages such as energy efficiency, low-noise operation and the low maintenance expenditures.
During modernisation, the drives are still being predominantly installed in machine rooms. And that often involves installations with 1:1 suspensions, i.e. with relatively large rope clearance.

For the compact drives from the SM200 series, Ziehl-Abegg is now offering a machine frame for the 1:1 suspensions, which can be easily adjusted to the local circumstances. For instance, diverting pulleys with different diameters are available, the length of the machine frame can be adjusted onsite and the rope distance can be adjusted without any great effort.
The upshot is that Ziehl-Abegg can now provide a compact drive package for modernisation from a single source, comprising the gearless elevator machines with mechanical hand release for the brakes, the ZETADYN elevator frequency inverter for installation in the machine room or in the elevator control as well as the advantageous machine frames with the corresponding pulleys.
