We develop instruments and systems for municipal public transport trolleybuses. Our engineering solutions offer increased operating safety, ensure passenger comfort and lower operating costs.

Display of instantaneous vehicle speed and other operating information

Display of instantaneous vehicle speed and other operating information

The TTU-32 display unit is used in connection with the recording unit as a tachograph.

Besides the instantaneous speed and the total driven distance, the display unit also displays other information like, e.g. time, temperature, pressure, battery charge, used and recuperated energy, etc. It is also able to run and evaluate a vehicle's brake test.

Together with a speed sensor, it may be used as a simple speedometer.

We offer several speedometer designs with digital or analogue, rectangular or circular displays.

Trip recording unit

Trip recording unit

The TTZ-62 is a recording unit used to record the operation of municipal public transport trolleybuses.

The most significant monitored value is speed. Based on recorded data of speed over time, it is possible to analyse the smoothness of travel, i.e. the driving qualities of drivers.

Other monitored values are the vehicle lighting usage, temperature inside the vehicle, measuring energy consumption with separate readings for heating and additional motors, recuperation, turn indicators, retarder use, etc.

Tachograph data analysis

Tachograph data analysis

We provide T62win and N62win software for evaluating and adjusting data analysing features

The software is simple, intuitive and very user friendly. The advantages are intuitive controls with context-sensitive help, graphical or tabular representation of data, statistical processing of operating parameters, etc.

Earth-leakage monitoring for trolleybuses

We manufacture earth-leakage monitors for electric buses and trolleybuses. Trolleybuses with our monitors operate throughout Europe. A timely warning of possible electrical shock increases the safety of passengers and drivers.
