Liebherr has launched a new truck-mounted concrete pump, the 37 R4 XXT. The German-built pump has a four-section, roll-fold distributor boom has a reach of 37m, and can be equipped with pump units featuring three different outputs ranging from 125 m³/h to 163 m³/h.

Built with a pump type THP 140 H, this equipment also features a Liebherr-patented XXT-narrow outrigger. It was unveiled at the World of Concrete event in Las Vegas.

The boom is extremely torsional-resistant, which ensures reduced vibrations when manoeuvring the boom during onsite applications.

A well-balanced weight distribution is achieved by channelling the concrete line extremely close to the boom on both left and right-hand sides, while pressure loss is reduced over the entire length of the distributor boom due to the generous 275 mm radius of the pipe bends.

Moreover, the pipe bends are predominantly of the same type, minimising the need to stock diverse replacement parts. Numerous design-related features optimise servicing tasks by simplifying the replacement of wear parts.

Liebherr is sole market provider of the exceptionally sturdy and low-torsion patented XXT-narrow outrigger. The front and rear support arms are secured directly to the pedestal of the distributor boom, through which the forces are channelled directly into the supports, completely bypassing the boom.

All four support arms are pivot-mounted to allow maximum flexibility and a particularly extensive working range of the distributor boom with narrow support configurations, a feature which is invaluable on construction sites with restricted access.

Chassis from various manufacturers can be used for the truck-mounted concrete pump in accordance with customer requirements.

These rugged and durable concrete pumps from Liebherr are developed and produced in Germany, and feature exclusively high-quality components from renowned manufacturers.
