Liebherr USA, Co. Showcased Machines at Demolition Austin
Liebherr USA, Co. Construction Equipment division were once again at the National Demolition Association’s Live DEMOlition event at this year’s annual convention. Liebherr featured three machines at this hands-on event – the R 946 LC and R 936 LC crawler excavators and the LH 22 M mobile material handler – as well as the L 556 XPower wheel loader.
The R 946 is the perfect machine for either second- or third-member demolition tools, with a hydraulic system that makes for easy transitions. At the push of a button, the summation of the bucket hydraulics and additional auxiliary hydraulics needed for a second member shear is done. The R 946 also features casting in all high stress areas to reduce the risk of failure in heavy demolition applications.
The R 936 crawler excavator weighs 38 tons, making it one of the biggest reduced tail swing excavators available in the market. It is also designed for working in small spaces. With a tight swing radius, this machine is ideal for urban and bridge demolition applications that require precision. This machine can be outfitted with demolition guarding that protects the machine super structure and cylinders.
The LH 22 M crawler excavator has a compact design, which makes it well suited for deployment on demolition sites. The latest engine and hydraulics technology, developed in-house by Liebherr, is built in on the LH 22 M Industry to deliver exceptional fuel efficiency outstanding material handling performance. Its reach of 36 ft (11m) is further enhanced by a variety of optional attachments that complement the machine’s power and performance in every application.
Equipped with the innovative XPower driveline, the L 556 XPower wheel loader delivers quick working cycles, high tipping loads and high machine uptime, which lead to increased handling capacity and higher productivity. The XPower driveline with Liebherr-Power-Efficiency achieves up to a 30% reduction in fuel consumption when compared to conventional travel drivelines. At highest efficiency, this reduces operating costs and increases profitability. The XPower driveline brakes automatically and the service brake acts only as a support and is subject to minimal wear.
Wheel spin on the L 556 wheel loader is prevented through continuous tractive effort control of the XPower driveline, combined with automatic self-locking differentials. Productivity is increased and tire wear reduced by up to 25%.
The L 556 XPower has safe and easy engine accessibility for daily checks. Critical maintenance points on the loader can be reached quickly, providing faster turnarounds and higher uptimes. And with a width of 9.6 ft (3m), length of 30 ft (9m), and weight of 27.5 tons, the machine’s profile is designed for the necessity of road transport.
