Liebherr 42 M5 XXT concrete pump options Powerbloc drive that may be changed in 2.5 hours
The brand new Liebherr 42 M5 XXT truck-mounted concrete pump debuts the corporate’s Powerbloc drive unit, which it says combines the very best options of open and closed hydraulic programs. Liebherr unveiled the pump on the World of Concrete this week in Las Vegas.

The pistons, in flip, are related to hydraulic cylinders which might be powered with excessive strain oil, which supplies the power to pump concrete.
Typical hydraulic programs function both an open or closed circuit design. Though Liebherr has sometimes used an open design on its concrete pumps, it says the sort of system additionally takes up extra space, requires extra oil and weighs extra. A closed circuit setup addresses these issues however incorporates extra elements and is subsequently extra advanced, says the corporate.

And the Powerbloc may be rebuilt after which utilized by house owners as stand-by spares.
The unit additionally has 90 p.c fewer hydraulic traces, Nichols provides: “There are mainly two predominant traces, a feed and return, and the remaining is difficult piping.”
The Powerbloc additionally frees up deck house on the truck deck, house that can be utilized for hauling different gear, Nichols says. Will probably be customary on all Liebherr concrete pumps going ahead.
