Key Features
Capacity & Mixing
Two Core Volumes
Pick the capacity that matches your route density and batching tempo — without changing the STU build approach.
Agile Cycles — Mechanical Jack
Nominal 12.7 m³ | Geometrical 19.930 m³ | Capacity in water: 13.040 m³ | Drum speed 0–14 rev/min | Fill: 15"/m³ | Unload: 15"–40"/m³ | Weight empty: 5,000 kg | 180° swivelling chute with mechanical jack
Maximum Output — Hydraulic Jack
Nominal 14.7 m³ | Geometrical 22.800 m³ | Capacity in water: 14.316 m³ | Drum speed 0–14 rev/min | Fill: 15"/m³ | Unload: 14"–40"/m³ | Weight empty: 9,700 kg | 180° swivelling chute with hydraulic jack for lifting
Drum & Wear Protection
Anti-Wear Steel Construction
30MnB5 anti-wear steel drum walls and mixing blades — engineered for demanding daily cycles.
30MnB5 Anti-Wear Steel
Drum walls and mixing blades: 4 mm 30MnB5 steel (HB 200/220) for maximum abrasion resistance.
2× Ø280 mm Rollers
Heavy-duty drum support rollers for smooth, reliable rotation under load.
Discharge & Site Workflow
Controlled, Clean, Confident
Designed to keep discharge controlled and clean — especially under real site pressure. The 12.7 m³ uses a mechanical jack; the 14.7 m³ uses a hydraulic jack for chute lifting.
Mechanical Jack Discharge
180° swivelling chute + support + mechanical jack. Anti-wear plate on discharging hopper. 2× inspection manholes + ladder.
Hydraulic Jack Discharge
180° swivelling chute + support + hydraulic jack for lifting. Anti-wear plate on discharging hopper. 2× inspection manholes + ladder.
Polystone Chute Extensions
2 lightweight Polystone extension chutes with holders for extended reach on both models.
Water & Additives
Consistency Is a System
600L pressurized steel water tank with additive handling capability.
600L Pressurized Tank
Pressurized steel water tank with level indication for consistent mix management — standard on both models.
Configurable Additive Tank
40L additive tank standard on 14.7 m³. Available by specification on 12.7 m³.
