Liebherr to display range of equipment and components at Bauma China

During Bauma China 2018, Liebherr will show a range of equipment and components. The Liebherr stands at the Shanghai New International Expo Centre (SNIEC) will be located outdoors (booth No. B12) and indoors in hall N4 (booth No. 524).

From November 27 to 30, Liebherr will display eight pieces of equipment for multiple industries and applications. The Liebherr outdoor booth will feature the R 966 and R 920 crawler excavators, the A 920 mobile excavator, the L 550 wheel loader, the PR 776 crawler tractor, the R 9100 B mining excavator and the HTM 804 QING truck mixer as well as the LTM 1300-6.2 mobile crane. Liebherr will present various components of mechanical, hydraulic and electrical drive systems and control technology at its indoor booth.

Mining Excavator R 9100 B
The mining division of the Liebherr Group presents the new R 9100 B mining excavator for the first time at Bauma China 2018. The new model replaces the R 9100, which has been on the market since 2012. This B-version has gone through a strong upgrade and improvement process. It is therefore expected to clearly deliver an incredible performance.

The Liebherr R 9100 B presented at Bauma China has an operating weight of 113 tonnes (125 tons) and is equipped with a 7.5-cubic-metre (9.8-cubic-yard) Evo backhoe bucket combined with the Liebherr Ground Engaging Tools. The Liebherr D9512 diesel engine delivers a performance of 565 kW (757 hp).

Crawler Tractor PR 776
The PR 776 is Liebherr's largest crawler tractor and will be on display in China for the first time. The machine falls into the 70 tonnes category and was introduced at Bauma Munich in 2016. It is designed for tough mining and quarry operations. It has a maximum operating weight of 74 tonnes and is equipped with blade capacities of 18.5 cubic metres (semi-U blade) or 22 cubic metres (U blade).

A unique feature in this machine class is the infinitely variable hydrostatic travel drive, which is used for all crawler tractors from Liebherr. The modern drive concept of the new PR 776 offers extremely efficient and safe operation to customers.

The PR 776 crawler tractor is powered by a 565-kW (768-hp / 759-hp) Liebherr 12-cylinder diesel engine.

Wheel Loader L 550
At the trade fair Liebherr exhibits the wheel loader L 550, an example of its expanding wheel loader product range for the Chinese market. Due to the hydrostatic driveline, Liebherr says that the L 550 consumes up to 25 percent less fuel compared with conventional wheel loaders under the same conditions. The optimum weight distribution of the machine increases the productivity at work, because larger buckets can be used to handle more material with each loading cycle.

The Liebherr wheel loader L 550 that will be on display is powered by a 140-kW / 190-HP diesel engine.

Crawler Excavator R 966
The 70-tonne-class R 966 will also be on display. Its optimized hydraulic system together with intelligent operating modes allows it to work at maximum productivity, whether in earthmoving or quarry operations. It features a V8 diesel engine with high torque even at low speeds. Additionally, it is equipped with a Liebherr bucket and tooth system, which guarantees easy penetration and simple extraction, where digging and breakout forces of 308 kN and 354 kN ensure fast and efficient working cycles.

Crawler Excavator R 920
The Liebherr R 920 crawler excavator will be on display at the 2018 Bauma China. The R 920 has an operating weight of 21 tonnes and an engine output of 110 kW / 150 hp. Equipped with the latest hydraulic system, it is suitable for light and heavy tasks. It also features an automatic centralized lubrication system and intelligent energy management, which increases productivity.

Mobile Excavator A 920 with Likufix
The A 920 Litronic wheeled excavator meets the requirements of exhaust emissions level IIIA / Tier 3 / China 3 and is ideally suited to construction sites with long driving distances.

Liebherr also demonstrates the advantages of Liebherr LIKUFIX system which enables attachments to be changed quickly and easily from the comfort of the operator's cab.

Truck Mixer HTM 804 QING 
The Liebherr HTM 804 QING truck mixer, which holds 8 cubic metres, provides easy and comfortable operation. The double-pole joystick enables the operator to control the drum directly while observing the concrete discharge. The height adjustment of the concrete discharge chute can be operated very easily.

Mobile Crane LTM 1300-6.2
The Liebherr LTM 1300-6.2 displayed in Shanghai is the successor to the LTM 1250-6.1. Its telescopic boom has been extended by 6 m to 78 m. Its load capacity has also been increased. It is designed as a simple folding jib crane and is the smallest luffing jib crane on the market providing crane operators with a low cost entry point into the luffing jib crane class.

A unique concept for the superstructure drive unit has been used on the LTM 1300-6.2. Instead of the twin-engine concept normally used on cranes in this class, the 300-tonner is powered by a single engine with a mechanical shaft. A mechanical shaft ensures particularly high efficiency and thus guarantees the economy of the new concept in terms of fuel consumption.

Components
At Bauma China 2018, Liebherr will focus on components for the tunnel construction segment, focusing on their new gearbox series and electric motors.

Components by Liebherr have been proven themselves in tunnelling projects around the world for several years now. For example, slewing bearings with a diameter of up to 9,000 mm, which keep turning cutterheads in India, Africa, the U.K. and China. Also axial piston units have shown their value in tunnelling applications. Liebherr hydraulic pumps are used, for example, in medium-sized tunnel boring machines for hard and soft rock with a diameter of up to six meters.

All individual Liebherr components are characterized by their particular robustness, reliability, availability and long life expectancy. the company says that they are perfectly matched to each other according to customer requirements and can be used as an integrated drive system, for example for the cutter head in tunnel boring machines.
