Liebherr to introduce concrete pump and hydraulic drive unit at World of Concrete
The Powerbloc drive unit is the first hydraulic system designed exclusively to power concrete pumps
Equipped with the popular five piece multi-folding mast, the 42 M5 XXT has an unfolding height of under 28.2 feet and a vertical reach of 135 feet. The low unfolding height and great mobility of the pump give the machine great boom flexibility and support in a compact unit.
In addition, Liebherr's XXT outrigger support system offers versatility in setting up the pump. It is safe and stable in any position thanks to the direct load transfer. A redesigned rear end permits easy access to the pump for operation and maintenance.
Meanwhile, the Liebherr Powerbloc is the new drive unit for the pump system. With this new design, all hydraulic switching and measuring elements are completely integrated, which eliminates numerous hydraulic hoses and other parts. This is a one-of-a-kind drive unit in the concrete pump world, as the Powerbloc is powered by a semi-closed hydraulic circuit, which supplies all drives with hydraulic energy. As a result of this new design, the oil volume is significantly reduced.

The all-new CASE TR340B compact track loader — operating at 90 horsepower with a 3,400-pound rated operating capacity — is the most powerful radial-lift CTL in the CASE lineup. Its all-new 8-inch LCD display improves on industry-leading CASE visibility with a new backup camera that is viewable in both forward and reverse operation. The display also showcases critical operating information and "trip" details. All-new electro-hydraulic controls, managed through the display, make it easier than ever for operators to dial CASE CTLs into specific application demands. All new cab controls and joysticks make the new TR340B easy to own and operate.
Industries such as construction, mining, energy, utilities and forestry, face many challenges when it comes to tracking assets and employees. Equipment often has to be transferred between locations, or monitored while it is dormant during off seasons. Lone workers may have to travel long distances or visit multiple sites during the course of their activities. And, all of this is further complicated today with shifting supply chains and economic realities putting further strain on the bottom line.
