Compare configurations
Compare concrete mixer truck axle configurations
| Configuration | Axle configuration and mixer capacity | Delivery pattern | Route fit | Main advantage | Selection limits and trade-offs |
|---|---|---|---|---|---|
| 4×2 Concrete Mixer | Compact two-axle mixer configuration for lighter project requirements | Smaller batches and short-distance concrete delivery | Urban sites and access-constrained projects | Compact chassis and site approach | Drum and legal-load requirements beyond the confirmed chassis |
| 6×4 Concrete Mixer | Three-axle driven-tandem configuration for balanced mixer duty | Routine plant-to-site ready-mix delivery | Urban and regional construction routes with suitable access | Balances mixer capacity, traction and manoeuvrability | Sites without enough manoeuvring or discharge space, or batches above the approved mixing and vehicle limits |
| 8×4 Concrete Mixer | Four-axle configuration for a larger approved mixer and concrete load | Higher-output construction and infrastructure delivery | Planned routes and pour sites accepting a longer vehicle | Supports a higher-capacity mixer within legal mass limits | Narrow access or routes with restrictive axle and dimension limits |
Choosing mixer capacity for the delivery route
A mixer's rated mixing volume and its geometric drum volume are different figures. Compare the concrete quantity you need to deliver with the rated mixing volume; the drum's total geometric space does not establish the permitted load. The completed truck's mass and axle limits govern how much concrete it can carry. Choose the axle configuration and final capacity within the approved chassis and project limits.
Review the delivery route's journey time and gradients alongside the water-system requirements. The truck must reach the site and discharge in the space available.
