The new manufacturing facility for compact 4-wheel-drive loaders and telescopic loaders at Kramer Company in Pfullendorf is one of the most modern factories in Europe. By selecting the continuous monorail hanger shot blast system RHBD-K Kramer is counting on the technical experience and know-how from Rösler.

Kramer-Werke GmbH, a subsidiary of Wacker Neuson SE, is one of the leading manufacturers of all-wheel drive construction equipment that is marketed under the name of Kramer Allrad. Kramer loaders are known for their modern design and first-class quality. To cope with increasing international demand for its products, in 2008 the company invested over 30 million Euro to build a brand new, state-of-the-art factory in Pfullendorf. The new production facility with an area under roof of 30,000 square meters was erected on a lot of 160,000 square meters. The building is equipped with an integrated paint system, a high rack warehouse and an office wing. Adjacent to the new building is a demo area for equipment demonstrations. This super modern facility is also equipped with a Rösler continuous monorail hanger shot blast system RHBD 15/16-K for de-scaling and de-rusting of different components like  castings, bent parts, forgings and welding fabrications prior to painting. The required surface finish is SA 2.5 or better.

An existing equipment system adapted to the specific customerrequirements

An important point in the customer’s decision for this shot blast concept was that Rösler had already built multiple machines of this type and had proven that they can be modified to specific customer requirements. For example the 26 meter long system had to be fitted into the new building.

The RHBD15/16-K blast system features an inlet and outlet vestibule allowing the blast cleaning of fist-size parts with a weight of around 1 kg up to components weighing 2 metric tons. Depending on the surface condition of the parts to be cleaned the speed of the monorail.

To allow manual touch up after the blast process in the mono rail shot blast machine Rösler installed a manual blast room adjacent to the outlet vestibule of the RHBD.  The system is completely encapsulated so that the noise level does not exceed 80 dB(A). Common blast media cleaning system reduces the cost by 30%

The blast media used in the manual blast room is cleaned and re-circulated by the highly efficient media classification system of the monorail blast system. Compared to the installation of two independent re-circulation and cleaning systems this combined blast media cleaning system costs 30% less. Another cost saving feature is the post filter system allowing the air from the dust collector to be so clean – free of dust – that it can be returned into the building resulting in significant energy savings. 

As an all-round supplier, Rösler GmbH is an international market leader in the production of surface finishing, shot blasting machines, painting systems and preservation lines  as well as process technology for the rational surface finishing (deburring, descaling, sand removal, polishing, grinding…) of metals and other components. Besides the German plants in Untermerzbach and Bad Staffelstein, the Rösler Group has branches in Great Britain, France, Italy, The Netherlands, Belgium, Austria, Switzerland, Spain, Romania, China, India, Brazil, South Africa and USA.system can be adjusted from 0.8 – 2 m/minute. The blast chamber is equipped with eight (8) blast wheels, type Hurricane H 42. The blast wheel speed can be adjusted by frequency inverters which guarantees optimum blast results for any surface condition. The blast wheels are mounted in groups of four on each side of the blast chamber. They are slightly canted in and against the direction of the parts flow. This wheel arrangement guarantees that the front and back side of the parts is also exposed to the blast stream.
