Liebherr twin-shaft mixers are particularly suitable for high outputs of pre-mixed concrete and are available in sizes of 3 to 8 cu yd. Their compact design is a particular advantage if used in mobile mixing plants and for construction sites with limited space. The well-built mixing equipment can, depending on size, process aggregates up to 7 in. without difficulty. That is especially important for mass-concreting projects such as dams, roads or bridges or other larger RCC pours, which require high-quality mixed concrete.
