THOR E2 – equipped for the future

THOR E2 is one of the most advanced and unser friendly lift controls right now. Based on a Linux operating system, it hardly knows any limits, from the graphic user interface via the intuitive operation and automatic error analysis through to the optional cloud connection.

And as you've come to expect from Weber, this control system is naturally also based on the CANopenLift standard (CiA 417), which has won through in lift engineering.

The THOR E2 computer has a modular design and is extremely compact.


Weber Lifttechnik GmbH specializes in the production of lift control systems based on CANopen CAI 417. The easy integration of CANopenLift modules and their safe data exchange were decisive for the assertion of this bus standard in lift engineering. The system is rounded off by an automatic module recognition and its uncomplicated parameterization facility.


The system knows virtually no limits where the software is concerned. Be it as a group lift, special hospital lift or as a car lift, the THOR E2 will feel right at home in every area. Special requirements can be implemented, too.

Visualization and intuitive operation

The self-explanatory user interface on the 5.45-inch touch display is one of the centerpieces of the THOR E2. The visualization makes the operability a whole lot easier.

  • Visual display of signals and movements
  • Jump directly to the desired menu items using the search function
  • Search function for parameters and terminals
  • Malfunctions, reports, parameters, functions in plain text and with help texts
  • All the parameterization directly at the processor, including the CANopen components
  • Mirroring of the original user interface of CANopen and DCP components, e.g. (Ziehl, Abegg, Brunner & Fecher, Fuji, Bucher iCon, etc.)


Your customers are based all around the world. Which is why German, English, Dutch, French, Swedish and Greek are already integrated ex factory.


With the EnergyIQ option, you'll acquire an energy-efficient lift control technology that saves the user money while also being a good contribution to climate protection.

Fast and faultless installation

Plug & use means installation cost savings for you. Install the preconfigured control elements, plug in the cables, start up – it couldn’t be easier!

Modular production:

  • Short delivery periods
  • Consistently high quality
  • Good price-benefit ratio

This way of manufacturing has the advantage that basic modules can be produced in larger quantities, and then expanded with other modules to meet the customer’s requirements.
