The latest Liebherr earthmoving machines arrive in North America

LIebherr

Liebherr will debut new-to-market excavators, dozers and intelligent assistance systems at Conexpo 2020 in March. 

The manufacturer plans to showcase an extensive selection of earthmoving and construction equipment at its outdoor booth. As well, the company’s product range of components for mechanical, hydraulic and electric drive systems will also be on display in the south hall of the Las Vegas Convention Center. 

Altogether, Liebherr’s products will fill more than 4,900 square metres of floor space. For its earthmoving division, Liebherr plans to introduce several machines to North America at the trade show. 

Gen 8 crawler dozers from Liebherr

Liebherr is introducing its latest Generation 8 dozers to North America at Conexpo 2020 with the new PR 736. 

Equipped with features that enhance operator comfort, grading characteristics and new standard grading systems, the PR 736 Generation 8 is a do-it-all machine for grading and mining. 

The PR 736 is powered by a 217 hp Liebherr diesel engine belonging to the EVO series. 

The dozer meets Tier 4 Final emission standards, and its exhaust is cleaned by a combination of a diesel oxidation catalyst and a selective catalytic reduction and particle filter. 

The machines’ operating weight is up to 25.5 tonnes. To cover a large application range, various blade versions with capacities from 4.1 to 5.56 cubic metres as well as many rear equipment options are offered.

Gen 8 crawler excavator 

The Generation 8 crawler excavator series is made up of seven models ranging from 22 to 45 tonnes, including: the R 922, R 924, R 926, R 930, R 934, R 938 and R 945. 

The R 926 and the R 938 will be exhibited for the first time in North America at the Liebherr booth. 

The highlights of the new crawler excavator generation include higher engine power, a heavier counterweight for improved bucket capacities and minimal fuel consumption. 

A new equipment concept with a modified piece at the top of the boom is an innovative new feature. 

This leads to better performance and equipment forces with reduced operating weight of the machine. Another feature is the optimized load curve, which yields reduced fuel consumption. 

The machines have been specially designed to provide extra comfort and safety for the operator, as well as optimum ergonomics and performance on the job site. 

Assistance systems 

Liebherr will present four wheel loaders at the show. This includes an L 566 XPower with power-split travel drive. Liebherr installs the drive as standard on its large XPower wheel loaders. 

The system combines short loading cycles with optimal hydrostatic drive with the mechanical drive, the benefits of which come into effect over long distances and up hills. 

The L 566 XPower is also equipped with numerous new assistance systems, which Liebherr is showing for the first time in North America at the exhibition. 

More from ConExpo:

These include active personnel detection, adaptive working lighting, an integrated tire pressure monitoring system and the weighing system with Truck Payload Assist. The L 566 XPower also has the new joystick steering for wheel loaders. 

The largest Liebherr wheel loader, the 32.6 tonne L 586 XPower, will also be at the exhibition stand. With a power split XPower drive, it delivers high performance and enormous fuel savings. 

The L 538 represents the Liebherr medium-sized wheel loader range. 

The loader  is equipped with parallel kinematics for high holding forces in the upper lift arms area. It is ideal for working in heavy-duty industrial applications such as in recycling with high dump buckets.

The Liebherr 920 Litronic wheeled excavator 

The Liebherr A 920 Litronic wheeled excavator on exhibit at the show has an operating weight of 18.3 to 21.3 tonnes and an engine output of 175 hp. The Liebherr wheeled excavator is particularly suitable for road, canal and pipeline construction as well as for classic earthmoving work and is characterized by high mobility and versatility. The strong undercarriage as well as the outriggers at the rear and front ensure stability and safety every time the machine is used. 

This enables the A 920 Litronic to carry out all work reliably, precisely and productively, even under full load. 

A 922 Rail Litronic 

The A 922 Rail Litronic rail-road excavator has an operating weight between 20.4 to 23.4 tonnes and an engine power of 163 hp. The excavator can be operated as a dual-purpose machine either on the road or on railway tracks. 

Thanks to the mobile undercarriage, it is possible to move the railroad excavator quickly. 

On either side of the excavator’s undercarriage a rail travel drive is mounted, which brings the tires to rail level. By using the inside wheels of the dual tires, the machine is able to travel on the tracks. 

Depending on the application requirements, the A 922 Rail can be equipped with a rail guide for normal and wide broad-gauge railways or with a friction wheel rail guide for narrow gauge railways.
