On the truck mixer market, semi-trailer models are gaining in importance all the time. High payloads and the ability to switch the tractor vehicles rapidly from one semi-trailer to another are the main reasons why they are being used increasingly often for concrete transport. If the operating company already has suitable tractor vehicles, they become even more cost-effective. Semi-trailers are also extremely manoeuvrable in urban areas. Their specifications can include a number of special features as options, including anti-lock braking (ABS), an electronically controlled brake system (EBS) and a Road Security System (RSS).

The semi-trailer has particular advantages in countries that impose severe vehicle axle-load limits, such as Belgium.
