The mobile Mix Master Duplex DFA


Can be attached to wheel loaders, forklifts, excavators and telescopic loaders. 

Using the hydraulic filling bucket, you can fill the mixer yourself by driving into the rubble, gravel or sand pile or other mixing components. 

Binders such as water and cement are added after closing the filling bucket. Mixing can take place while travelling to the point of use. 

Depending on local conditions, the concrete can be emptied to the side via the discharge chutes on the left and right.

Using a wheel loader, for example, the mix can also be emptied onto a truck bed or trailer via the hydraulically folding filling bucket.
