Business profile
Wacker Neuson’s long history of innovation began in the mid-19th century and more than 50 years ago the company heralded the power generation with its wireless rammer
T
hat invention was soon followed by the first gasoline-powered breaker engine recording 1150 impact
blows a minute. Today, Wacker Neuson’s BH 55rw (railway) gasoline demolition hammer stands out as an entry-level model in the process of effectively compacting railroad ballast. The model boasts 55 joules of single stroke impact energy at a rate of 1,350 blows per minute yet remains economical with low-emission impact. Maintaining the railway system involves special requirements for track construction because railroad ballast must always be re-treated. Tamping requires a fairly gentle force because the ballast cannot be damaged in the process. However, a certain percussion rate is required so that the ballast is properly compacted. Wacker Neuson, which also offers a global spare parts service, stepped up to this challenge and designed a gasoline-powered hammer specifically for track construction.
Robert Brauneis, product manager for worksite technology at Wacker Neuson, said: ‘It is an ideal combination of percussion rate and force for the special requirements on the track. Together with specialists from track construction, we precisely adapted the BH 55rw so that it provides ideal conditions for working on the track. Railroad ballast is optimally compacted but the ballast itself is not damaged during the work.’
Economic, safe and user-friendly In order to ensure this combination, all components of the BH 55rw are ideally adjusted to one another. The impact force of 55 joules that is gentle on the material is compensated for by the very high percussion rate of 1,350 blows per minute. Its simple percussion system allows for maintenance on site with a small grease gun over the central zerk fitting. The proven Wacker Neuson full-hood spring mounting, which provides for low hand-arm vibrations and optimally supports the operator during his work, together with a power- to-weight ratio of 24 kg, also contribute to track work functioning perfectly with the BH 55rw. Hand-arm vibration is under the limiting value of 5 m/s². This
allows for a continuous use up to eight working hours per day. Lighter and smaller than other demolition hammers, it’s designed for professional use and is noted for its compact size and ease of use. It also includes shanks for all common tools. The BH 55rw can also be refueled while the unit is in the vertical and horizontal positions. The Wacker Neuson Group includes the product brands Wacker Neuson, Kramer Allrad, Kramer and Weidemann. In 2012, the group achieved revenue of €1.1 billion and employed more than 4,000 people worldwide.
‘ECO’ for environmental protection and efficiency
The gasoline hammer BH 55rw is equipped with the WM 80 engine that stands out for its low consumption, excellent starting behaviour, high quality and long service life of engine components. The economical and low-emission WM 80 gasoline engine is perfectly suited for the unit and is extremely reliable. Thus, the hammer has been assigned the Wacker Neuson ECO seal – given to proven product solutions and entirely new products which are
particularly low in emissions as well as efficient.
Martin Lehner, chief technical officer
Wacker Neuson SE is responsible for purchasing, production, technology and quality. He said: ‘The fact that the issues of environmental protection and efficiency have been on the agenda for a long time at Wacker Neuson is confirmed
by some of our proven solutions.’ •
