The truck mixer pump TWINSTAR 3Z21 is the suitable choice for flexibility, dynamism and reliability. Thanks to the boom in 3 sections with "Z" folding type this model has been designed for small jobsites, usually for residential building. The TWINSTAR 3Z21 has a minimum boom opening of 5.4 m only, suitable for urban construction sites with difficult access thanks to the front outriggers  "horizontal" opening. Perfect assembly on truck:
- 3 axles with wheelbase 3.500 mm.
- 4 axles with wheelbase 4.250 - 4.550 mm.
Drum high load capacity with elliptical bottom with nominal capacity 8 . The pumping group G7 designed to optimize the best relation among suction and concrete pumping that realize max theoretical concrete output max 80 m³/h and pressure on concrete up to 80 bar.
