Liebherr cranes meet stringent European VI c emission standards under real driving conditions.

Aiingen crane manufacturer is pleased with the good test results of the extensive PEMS test system (portable emission test system)

The emissions are equivalent to heavy long-distance trucks.

November 2019 eingen/donau (Germany)

Schwaben crane manufacturer and Germany TÜ A series of recent tests conducted by V NORD and engineering partner IAV automotive of Germany proved that even large liebherr cranes, such as the LTM 1160-5.2 of 5 bridge, with a road driving weight of 60 tons, actually meet the stringent European VI c emission standards for road driving.

While much of the public debate about diesel engines and their emissions has focused on trucks and cars, the issue of emissions has also been high on the agenda at crane maker liebherr. Compared with trucks, mobile cranes are subject to non-road standards whether on roads or on construction sites. Modern mobile cranes with a single engine concept have only one engine and can operate on roads and construction sites. All certified diesel engines installed on mobile cranes in the European Union, Switzerland and Norway after 2019 must meet European V emission standards. These requirements are similar to those of the European VI c highway standard.

overview of emission phase development

& other; We've been doing research for more than 20 years, and a significant portion of our r&d budget is devoted to reducing emissions. During this period, we have succeeded in reducing nitrogen oxides and soot particles, that is, fine dust, by about 97% in stages. Throughout the &; Dr. Ulrich Hamme, technical director of liebherr aiingen, said. Prior to the transition from our crane fleet emission standards to phase V, we conducted several months of field trials with ESB, a Biberach based crane leasing company, to observe and improve the performance of diesel particulate filters and urea dosing systems under realistic conditions. Throughout the &; Over the past few months, a number of PEMS (portable emissions testing system) tests have been conducted, from TÜ V NORD and IAV experts are also involved.

from TÜ VNORD and IAV experts are installing test equipment

Dr. Hamme sums it up this way: These measurements are another pioneering and forward-looking milestone in our steady development of crane engines and gearboxes, compared to modern trucks produced by well-known German manufacturers. Throughout the &; In practice, in the absence of a test bed, in other words only on a standardized typical road, including not only urban traffic but also rural and highway traffic, the Mercedes Actros 1842 with a load of 40 tons was compared with the LTM 1160-5.2 with a load of 60 tons of liebherr crane. From TÜ V NORD testers and experts with extensive PEMS measurement experience from the IAV monitored the entire trip around eingen and ulm. TÜ V NORD project manager Martin Goschü Dr. Tz says: The measurement ensures that everything works normally, the measurement system is carried out at the exhaust pipe, and the measurement results are recorded independently.

After three months of testing, Daniel Lü from IAV; Deritz presented the test results in eingen, and the assessment results showed a clear conclusion - the liebherr crane emissions for off-road emissions phase 5 are fully compliant with the European VI c PEMS standard under real driving conditions. & other; Cranes emit as much carbon dioxide and carbon monoxide as trucks do, and hydrocarbons are even lower than trucks get measured. Throughout the &; From TÜ Goschü of V NORD corporation; "Said Dr. Tz.

LTM 1160-5.1 on the way of measurement and comparison truck

Dr Hamme, general manager, said: Compared with trucks, the number of mobile cranes used worldwide is very limited, with each vehicle traveling only about 10,000 kilometers per year. Happily, PEMS test results show that in fact our emissions standards for mobile cranes are absolutely no less than those for long-distance trucks. It shows us that despite the short annual range, we are doing the right thing to make sure we are using the latest engine and gearbox technology. Coupled with an advanced and efficient emissions treatment system, our mobile cranes have now met this test status, which means we are setting the benchmark for cleanliness and the environment. Throughout the &;

Emission standards stage V: legislation on emissions from mobile machinery and equipment in the European Union (eu) regulation 2016/1628. The code includes the type of engine, emission limits, launch dates, durability requirements and a set of administrative guidelines for the current eu phase 5 emission standards for mobile machinery and equipment designed for non-road traffic.

successful test – IAV is explaining the PEMS test results

European standard VI c

The European standard VI c is an emission limit for trucks in the European Union based on the European parliament code for commercial vehicles. The fixed part of this code includes the testing of the vehicle in actual use.

{ PEMS test _8}

The PEMS system (portable emission measurement system) is a mobile emission detection device for actual driving. In order to determine PEMS emissions on public roads, in-service vehicle compliance procedures (emissions during use) were also used. For ISC testing, the vehicle was equipped with PEMS mobile emission measurement technology and tested for nitrogen oxide (NOx), carbon monoxide (CO) and hydrocarbon (HC) limits in actual road traffic.
