ZF in Concrete Mixers

In driveline technology for truck mixers ZF is extending its lead in the world's market. Vehicle manufacturers from the USA to China put their trust in the high quality of ZF mixer transmissions. ZF fulfills this demand through continual product innovation.

ZF presents the new generation of the ECOMIX range type CML 10 (Concrete Mixer Lowspeed) for concrete mixers up to 16 m³ drum capacity and an output torque up to 72,000 Nm. Mixer transmissions ECOMIX II are based on the achievements of the first Ecomix generation, however, they are smaller, lighter, tougher, more flexible, quieter, more noise reduced and easier to service.

The Ecomix II transmission series CML in comparison to previous models with PLM is approx. 24 % lighter and 50 % shorter. However, the special design of the new mixer transmission range Ecomix II also offers a wide range of further advantages. Thanks to a tough bearing concept it was possible to significantly increase the output bearing strength, which leads to less sensibility at off-road operation. The use of patented Elastomer units from ZF Boge Elastmetall allows an increase of the axial run-out at drum bottom and an increase of misalignment of the drum. With the new bearing concept the installation angle is no longer dependent on drum size and drum filling. An installation angle up to 20° is always possible. Acoustic and mechanic descoupling of drum and vehicle frame leads to considerable noise reduction during operation and improved driving comfort.

Serviceability has been improved thanks to an adapted, weight-optimized, low-speed-hydro motor and separate oil for transmission and hydrostatic as well as an improved accessibility. Instead of the previous sealing collar, a cassette seal is used. This makes the transmission tougher and the lifetime of the motor is increased. The compact light design offers the vehicle manufacturer more freedom in design and facilitates the assembly.
