Central locking System (ZFS)

Modular structure

The modular central locking system unit ZFS offers diverse configurations with only a few components, which take into account every customer requirement. With the ZFS and a wide pallet of compatible castor series, the user can structure his own mobility requirement individually and differentiate in the market with regard to security, ergonomics and design.


The free configuration of the ZFS, according to design, makes possible a safe full locking of all 4 castors of an operating resource or a low-cost partial locking for operating resources which are also castor functionally-stable with 2 locked castors. In both cases it is ensured mechanically that the castors are simultaneous locked or freely running. Known faulty applications are excluded as a result of this and provide for maximum efficiency.


Independently of the full or total locking selection, operation can be realized on one sided or on both sides. In this way individual ergonomics requirements are taken into account. The coding of the operating pedals in color is self-explanatory and signals the system status directly and unambiguously.


The simple and almost tool-free shortening of the transfer bar linkage enables dimensions to be realized almost without restrictions – within the framework of typical sizes of manually-shifted operating resources.


Different weights of the operating resources and their mobility requirements in rolling resistance, swivel characteristics, locking quality, as well as design demands, are correspondly handled by the great number of usable castor series.
