LM-S4000 highlights
The LM-S4000 tops the synchronized rotary range with a 4.0 m³ batch and the stronger Yuchai 4108 engine. It is built for contractors who need transit-mixer volumes but keep working beyond the reach of a batching plant.
Same 270° synchronized rotation and bidirectional driving as the rest of the range, with bigger water tanks, a heavier frame and a 2,350 mm discharge height suited to truck-mixer loading and formwork pouring.
- 4.0 m³ per batch — the largest in the rotating-cab range
- Yuchai 4108 engine, 91 kW / 124 hp
- 950 L water tank for continuous large pours
- 270° synchronized rotation with 180° fan discharge
- Bidirectional driving on narrow and steep sites
- Electronic hydraulic weighing system (±0.5%)
