LEITNER is an ISO 14001 accredited organization and maintains an environmental management system. Sustainability plays an important role across the group, as is particularly evident from the synergies between the individual companies. Ropeways are not the only systems for which the LEITNER direct drive has proved to be an innovative and sustainable technology. In 2003, the direct drive provided the technical foundation required for LEITNER to enter the renewable energies sector with LEITWIND wind turbines. Here, the drive is used in reverse operation as a generator. Today more than 183 ropeways and 365 wind turbines are already using this drive system.
The world’s only gearless drive system for ropeways enables significant cost savings. The LEITNER DirectDrive works using a synchronous motor with an output shaft that is directly linked to the pulley wheel. In contrast to conventional planetary gear drive systems, absolutely no engine oil is required and it consumes approximately five percent less energy. The logical next step up from DirectDrive is the LeitDrive frequency inverter. It converts the mains voltage and regulates the speed of the motor, ensuring the system has the power it requires This new technology is especially environmentally friendly. The waste heat can be used for heating and hot water.
Two chairlifts from LEITNER in LAAX demonstrate that modern systems can be really comfortable and powerful as well as economic and sustainable. With LEITNER direct drive, solar installations, CO2-free power and local timber, Weisse Arena Bergbahn AG has adopted a comprehensive and sustainable approach.
