Liebherr 47 M5 XXT Truck-Mounted Concrete Pump
Liebherr claims its updated 47 M5 XXT truck-mounted concrete pump offers added customer value. In-house development and optimisation of the mast is said to have been at the forefront of the latest model version. An array of other new design features will, says Liebherr, simplify the replacement of wear parts for more efficient servicing.

The 47 M5 XXT pump’s new 47m, five-section multi-fold distributor boom is said to be extremely torsion-resistant, ensuring that vibrations are reduced to an absolute minimum when unfolding the boom on the building site. To ensure a balanced weight distribution, the concrete pipeline is configured close to the boom on both left- and right-hand sides. Minimal pressure loss over the entire length of the distributor boom is guaranteed by the pipe bend in the concrete pipeline featuring a radius of 275mm.

Moreover, the pipe bends used are predominantly of the same type, minimising required storage of various wear parts. As a whole, the compact boom package – with no overhang at the rear of the vehicle chassis – in correlation with the truck-mounted concrete pump design, lends the overall vehicle an articulate and tidily-arranged appearance.

Patent protected, and therefore said to be the only one of its kind available on the market, 718 Liebherr's XXT narrow support is low torsion and extremely robust. The front and rear outriggers are secured directly onto the boom pedestal of the distributor boom, ensuring that all forces bypass the boom completely and are channelled directly into the outriggers. Four pivoting outriggers guarantee maximum flexibility and an extremely wide swing range of the distributor boom when supporting in a narrow configuration. This can prove decisive when working on building sites with restricted access.

The truck-mounted 47 M5 XXT can be equipped with two high-pressure pump units featuring varying performance outputs. Pump unit 140HL conveys up to 140 m³/h concrete, whereas the 160HL is capable of up to 160 m³/h concrete.  Depending on respective customer requirements, the 47 M5 XXT can be arranged on a four-axle chassis from selected manufacturers, including MAN or Mercedes.

A wide range of optional accessories and equipment is available for the 47 M5 XXT. This allows the customer to opt for extra storage compartments, for example, or a second diesel tank or an additional access point on the left-hand side of the vehicle. A magnetic rotating flash provides added safety and a pneumatic pinch valve on the end hose prevents concrete spillage when repositioning the boom.

    Several aspects factor into choosing the proper concrete dowel drill - Randy Stevens. The concrete paving industry has seen significant changes to dowel drilling equipment over the years. Many years ago only hand-held models existed and when the first hydraulic drills were launched over 30 years ago, these increased production and reduced labour needs. Since that time pneumatic drills, have come to market and these are driven by air compressors, which are common on many worksites while the units also have l
