ZF ECOMIX II – Low-maintenance operation for concrete mixers

With the CML (Concrete Mixer Lowspeed) series, ZF presents the second generation of the ECOMIX range for concrete mixers up to 16 m³ mixing capacity and an output torque of up to 90,000 Nm. Mixer transmissions ECOMIX II are based on the achievements of the first ECOMIX generation, however, they are smaller, lighter, tougher, more flexible, quieter, easier to service and more efficient.

The ECOMIX II transmission series CML in comparison to previous models are approx. 25 % lighter and 40 % shorter (fig 02). However, the special design of the 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 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 decoupling of drum and vehicle frame leads to considerable noise reduction during operation and improved driving comfort (fig 03).

Serviceability has been improved thanks to an adapted, weight-optimized, low-speed-hydro motor and separate oil for transmissions and hydrostatic as well as an improved accessibility. The new concept offers also a higher efficiency which leads to fuel and cost savings for the operator. The compact and light design offers the vehicle manufacturer more freedom in design and facilitates the assembly.
