TWINSTAR 4Z28

The truck mixer pump TWINSTAR 4Z28 is the suitable choice for flexibility, dynamism and reliability. Thanks to the boom in 4 sections with "Z" folding type this model has been designed for small jobsites, usually for residential building. The TWINSTAR 4Z28 has a minimum boom opening of 6.3 m only, suitable for urban construction sites with difficult access thanks to the stabilization front and rear "telescopic horizontal" type.
Perfect assembly on truck 4 axles with wheelbase 4.200 - 4.500 mm.
Drum high load capacity with elliptical bottom with nominal capacity 8,5 m³.
