Liebherr Twin-Shaft Concrete MixersAvailable in sizes ranging 3 to 8 cubic yards, a compact design suits the Liebherr twin-shaft concrete mixers to use with mobile plants and on sites with limited space, says the manufacturer. Fed on site by a dry-mix plant, the twin-shaft mixer is installed on a trailer for quick transport and placement. Mixed concrete is then discharged onto a high-speed conveyor belt, feeding either a holding hopper or directly into a truck. Depending on mixer size, aggregates up to 7 inches can be processed, and a standard recipe requires only 30 seconds of mixing time. The 3-cubic-yard twin-shaft model has a single electric motor; the larger models have two.

The R 9200 excavator matches haul trucks with payloads up to 154 tons.
