Liebherr Introduces New Diesel Engine for Mobile Harbour Crane Fleet
Jun 3 15
The Liebherr Group has introduced the new 12-cylinder Liebherr stage IV/Tier 4 final diesel engine for its mobile harbour crane, or LHM, fleet. The smaller crane models LHM 120, LHM 180 and LHM 280 will be equipped with a stage IV/Tier 4 final 400 kW engine. The bigger crane models LHM 420, LHM 550, LHM 600 and the new giant LHM 800 are available with a stage IV/Tier 4 final 725 kW diesel engine. Both diesel engine versions can be boosted with the Pactronic hybrid drive system for up to 100% extra power. For the latest European Union emission standard stage IV and Tier 4 final of the US Environmental Protection Agency respectively, Liebherr has intensively optimised the whole combustion process. Compared with other solutions, Liebherr developed a simple but effective solution that reduces the nitrogen oxides (NOx) emissions while cutting operating costs. An essential part of the new engine generation is the gas emission treatment. To simplify the system and to optimize exhaust gas after-treatment, Liebherr engineered the Selective Catalytic Reduction technology (SCR), which reduces particles to a minimum already inside the engine. This leads to economic advantages for the customer: As the particle emissions are already lower than the emission limits, no more reduction measurements are necessary. In this sense, the motor's characteristics in terms of power, efficiency and economy are further optimized. The newly designed SCR catalyst and all other system components such as injector, air- and AdBlue-pump contribute to a significant NOx reduction of approximately 98%. With the stage IV/Tier 4 final, Liebherr offers a standardized basic engine that can be adapted to the emission requirements in different markets and regions by minor modifications or by fitting exhaust gas after-treatment systems. Specifically, that means that the engines in the emission standards Tier 2, Tier 3 and Tier 4 have the same performance, the same parameters for the cooling system and the same interfaces for installation. That enables customers to substantially simplify their machine design by allowing engines with different emission standards to be exchanged in the same machine. That is an important advantage for any equipment that is used all around the world.
Liebherr Updates its 160 EC-B Flat-Top Crane and Unveils its Successor, the 172 EC-B 8 Litronic
Oct 16 14
Liebherr has updated its 160 EC-B flat-top crane and unveiled its successor, the 172 EC-B 8 Litronic. The crane's lifting capacity has been increased to provide users with increased performance. The crane's erection process has also been simplified even further. The redesign of the new 172 EC-B 8 Litronic Flat-Top crane has resulted in a major increase in performance in terms of its lifting capacity. Its lifting capacity has in fact been increased by 15% over the full length of the jib. The new Flat-Top crane will now hoist 2,100kg at the jib head with a radius of 60.0m and offers a maximum capacity of eight tonnes. This represents an increase of 250kg at the jib head over its predecessor. The modular concept and the compatibility of the tower systems among each other ensure that the crane is suitable for a wide range of uses. With the Liebherr 120 HC, 170 HC or 256 HC tower systems, free-standing hook heights of up to 71.4m can be achieved. Another new feature of the 172 EC-B is the new erection concept for the jib. The load hook and trolley remain on the jib pivot section during transport. That completely eliminates the erection work for the trolley. The hoist and trolley travelling ropes can also be reeved easily with little effort providing massive benefits particularly for jib erection in the air. Improved quick-release fastenings on the cab and switchboard platform allow the compact head to be split quickly to reduce the erection weights. And the quick-release electrical connections ensure that the switchboard and cab can be connected quickly without any errors. The Liebherr 37kW frequency converter hoist gear is included in the basic version and allows empty hook speeds of 135m/min. A 45kW frequency converter hoist gear is also available as an option. The frequency converter hoist gear is only used in 2-line mode. Hook heights of up to 328m and empty hook speeds of up to a maximum of 177m/min ensure that the crane is economical to use. The new 172 EC-B 8 Litronic is supplied with an advanced Litronic crane controller. Functions such as redundant load moment measurement, manipulation-proof commissioning and the monitoring of hoist gear brake with managed lowering in emergency mode provide a very high level of safety. Settings such as slewing gear modes and the trolley speed can be adjusted quickly and easily using the electronic monitor system (EMS). In crane mode, the increased sensor resolution of the new Litronic crane controller system also provides improved operating properties. The increased sensor resolution provides the basis for sensitive and precision operations even at high speeds. This results in enhanced crane operation comfort and much greater safety on site.
Liebherr-International AG Concludes an Agreement with Kamaz OJSC to Develop New Engine Line
Apr 2 14
Kamaz OJSC and Liebherr-International AG have concluded an agreement to develop a new engine line. The agreement builds upon and specifies the cooperation matters envisaged in the agreement concluded in 2013. Under the new agreement, Liebherr-International AG will assist Kamaz in developing the next generation of diesel and gas engines designed for the new family of Kamaz trucks and buses and stationery diesel and gas generators. For that purpose, Kamaz will set up modern production facilities in Naberezhnye Chelny. Liebherr will provide technical and consulting services regarding calculations, design, procurement, installation and launch of production equipment.
