With more than 620,000 visitors from over 200 countries, bauma 2019, the world’s leading trade fair for construction machinery, building material machines, mining machines, construction vehicles and construction equipment, generated the best results in the exhibition’s 65-year history. The number of visitors rose by about 40,000 over the total produced during the previous event in 2016. More than 250,000 visitors came from countries outside Germany. The number of exhibitors totaled about 3,700 from 63 countries – likewise a record. With its unprecedented 614,000 square meters of space, the largest bauma ever held was once again a bauma filled with records.
Also for BU Power Systems this year’s bauma was an exciting and successful show. At bauma 2019 Perkins highlighted three hybrid power solutions through three engines, all at 75 kW (100 hp). To demonstrate modularity and flexibility, all three hybrid solutions were based on the Perkins® Syncro 2.8 litre.
The technologies shown were hybrid-electric, hybrid-mechanical and hybrid-hydraulic:
Hybrid-electric: There are several ways to incorporate the electric motor or generator, with Perkins preferred arrangement delivering excellent fuel saving benefits while moderating the installation impact and minimizing the cost impact on the machine. The flexibility of the system provides opportunities for further efficiency and functionality improvements in the whole machine through use of 48-volt electrics.
Hybrid-mechanical: This stores energy in a high-speed flywheel which can be delivered back to the machine. This is particularly useful in hybridizing machines that run a cyclic operation and need very intense bursts of additional power. Apart from the very quick energy release, the advantage over hybrid-electric is in installation size.
Hybrid-hydraulic: This stores energy in hydraulic accumulators. In some machines this can be the most practical and cost-effective hybrid solution as it easily integrates into existing machine hydraulic systems. Software and integration of machine systems are key to achieving great savings from this technology.
“For some machines and specific requirements such as mini excavators and compact wheeled loaders, full electrification of vehicles is already a practical commercial proposition,” said Matt Coleman, product director at Perkins. “It is possible to replace a diesel engine with lithium-ion batteries and an electric motor. However, the dynamics of the defining features such as battery durability, cost, recharging infrastructure and product support, do not immediately translate into an attractive fully electric proposition for all operators of construction machines. Since the customer value proposition is very diverse, the range of solutions is equally diverse. One size does not fit all. The technologies that Perkins is proposing offer practical benefits in terms of productivity and operating costs in a much shorter timeframe.”
