Liebherr crawler concrete pump for bored piling foundations

Liebherr's newest crawler concrete pump the THS 110 D4f-K features a maximum concrete output of 133 yd³/h (102 m³/h) powered by a six-cylinder engine an is equipped with a powerful pump unit, known for its smooth operation and powerful suction. An open hydraulic circuit guarantees reduced system maintenance requirements. Additional structural details also contribute to optimum serviceability. High importance was afforded during the design phase to ensure that wear parts could be replaced quickly and easily. The smooth surfaces of the pump housing are easy to clean and the shape of the concrete hopper, devoid of edges and projections, minimizes the accumulation of concrete residue and soiling. An extensive standard scope of delivery for the crawler concrete pump includes for example, a 500-liter capacity water tank with water pump, as well as a lockable toolbox.

The THS 110 D4f-K crawler concrete pump is particularly suited for applications in which pumping of the concrete is constantly being relocated around the building site. The operation of the crawler track-mounted concrete pump is maneuvered via remote control.

Besides the THS 110 D4f-K, the range of Liebherr crawler concrete pumps encompasses two more models - the smaller THS 80 D4f-K and the larger THS 140 D4f-K with maximum concrete outputs of 93 yd³/h (71 m³/h) and 177 yd³/h (135 m³/h) respectively. A typical application for crawler concrete pumps is the supply of concrete to drilling equipment for bored piling foundations. Deep holes are drilled into the earth and then filled with concrete following extraction of the drill. Crawler concrete pumps are employed alongside the drilling equipment at the various operation points, while the concrete hose remains permanently connected to the drilling equipment.
